About Us

In 2024, we made two pivotal decisions: the expansion of our Gumi M Campus to support greater growth and the adoption of our new corporate name, CMTX. These were not mere changes in physical scale or branding, but firm commitments to prepare for the next decade built on the foundation of our past ten years.

Now, as we enter 2025, we face a new challenge. This year, CMTX is placing its full focus on R&D, not simply to accumulate technology, but to develop innovations that redefine markets and set new directions. Our goal is to become a benchmark company, one that leads and defines the industry, rather than follows it.

At the heart of this ambition are CMTX’s process technology, production efficiency, and quality stability, which we have continuously strengthened over time. Cost competitiveness is a measure of our true capability. It serves as both the foundation of technological progress and the starting point of customer trust. We are not a company that seeks to produce cheaply, but one that knows how to produce precisely and with excellence.

CMTX continues to evolve within a global supply chain closely connected to major semiconductor manufacturers, consistently meeting higher technological and quality standards. These challenges drive us to become an even more resilient and advanced technology company.

The year 2025 also marks a new responsibility for CMTX. We are preparing for an initial public offering (IPO) as part of our pursuit of transparent management and sustainable growth. At the same time, we are advancing initiatives in resource efficiency and responsible production. By progressively introducing a silicon recycling program, we aim to establish a resource-circulating manufacturing system that supports our long-term sustainability.

CMTX is a company whose tomorrow shines brighter than today, growing together with those who share our vision. We sincerely appreciate your continued trust and support.

Thank you.

We extend our heartfelt appreciation to everyone who has supported CMTX and visited our website.

As a global materials and components company, CMTX produces silicon parts for etching equipment, sapphire parts for deposition equipment, and ceramic parts used in semiconductor front-end processes. Since our founding in 2013, we have grown into a trusted partner across a wide range of industries, including semiconductors, displays, defense, and precision medical devices. We hold industry-leading expertise in silicon parts manufacturing (ring, electrode), from precision machining and lapping/polishing to hydrofluoric acid etching, and continue to lead the development of new products through sustained R&D investment, solidifying our position as one of Korea’s major silicon parts manufacturers. In addition, we possess world-class sapphire parts manufacturing technology (nozzles, injectors, etc.), recognized globally for its unmatched precision and quality.

Growth and Advancement

Since its founding in 2013, CMTX has focused its full capabilities on high-hardness precision component manufacturing for semiconductor equipment. Within just four years, we achieved remarkable growth within the industry (market).

In November 2017, we relocated to a new 3,000-pyeong headquarters in Gumi, Gyeongbuk, establishing a stronger foundation to lead the semiconductor industry.

Driven by continuous growth, CMTX has expanded its front-end manufacturing lines for silicon parts, invested in new production capacity, and acquired one of Korea’s few hydrofluoric acid etching licenses, becoming a fully integrated silicon parts manufacturer.

Our rapid rise stems from a shared vision among all employees, a steadfast commitment to customer trust, and proactive investment in R&D, product innovation, and new product development.

Staying true to our founding spirit, we will continue to challenge ourselves and grow, never ceasing in our efforts to repay the trust and confidence you have placed in us. CMTX aims to evolve as a materials and components company recognized by customers for its quality and agility.

Building the World Together

At CMTX, we take co-development with our clients seriously and value the time spent in genuine collaboration.

By collaborating with many companies on research and development projects under a co-growth policy that encompasses every stage from design and prototyping to mass production, we have earned recognition from numerous partners for our technological capability and reliability.

Our Corporate Culture

The CMTX family respects people and places trust in each other’s values. Every employee takes the lead in creating a corporate culture we would proudly recommend to our own children.

We are building a workplace where we work hard and enjoy life fully, a manufacturing company offering benefits on par with IT startups, and an organization that ensures equal opportunities for all through fair and objective thinking and through creative, proactive participation.

Every one of us believes that our society and nation can move forward only when we ourselves take the lead in fostering and practicing a transparent, fair, and clean culture, and we put that belief into action every day. Refusing to settle for the present, CMTX is preparing for a new era through continuous innovation: developing new materials and components, creating new products that enhance cost efficiency and yield, diversifying exports, and pioneering entirely new markets. Striving to become a truly enduring company, we will uphold our social responsibilities and help create a prosperous, livable, and inclusive world where everyone can grow together.

We sincerely ask for your continued trust and encouragement.

Thank you.

For COMA Technology, 2020 was truly a year of innovation. From technological breakthroughs and production system advancement to organizational refinement, every capability we had prepared for years finally came to fruition.

A major milestone was our registration as a supplier of Samsung Electronics, which brought a sharp rise in sales and marked our growth into a company recognized for both its technological excellence and product quality.

In 2021, our mission is to prove our reliability through technology to the customers who have placed their trust in us. By proactively identifying customer needs and further elevating our quality standards, we aim to reinforce the confidence that comes with the name “COMA Technology.”

This year also represents an important step forward as COMA Technology acquires and establishes SELIG, a company specializing in silicon ingot production, broadening our business scope and creating a stronger foundation to lead the materials market. This is more than an expansion. It is a milestone in building responsiveness to front-end industries and establishing a fully vertically integrated competitive system.

Now, we must once again embrace our vision and mission: To lead with technology, earn trust through quality, and stand with our customers in sincerity.

I have complete faith in the strength of our team, and together, we will continue to take on new challenges. To our customers, we will repay your trust with even greater reliability.

Thank you.

When we first began our journey in 2013, with deep reflection and no small amount of fear, we could not have imagined how far we would come. Today, that first step has borne meaningful fruit, thanks to the trust and encouragement of so many. Four years later, COMA Technology marks another major milestone with the opening of our new headquarters in Gumi, Gyeongbuk.

Guided by the management philosophy of putting customer satisfaction first, our entire team has moved forward with an uncompromising commitment to technology and quality. As a result, we have grown into a specialized manufacturer of semiconductor equipment parts, equipped with Korea’s leading material processing technologies, and have climbed steadily upward on the foundation of our customers’ trust.

Our relocation to Gumi is far more than a simple move. It represents a strategic investment aimed at enhancing production efficiency and product quality, and it embodies our philosophy of technological excellence and quality management.

The decision by all our employees to relocate their families from Gwangju, Gyeonggi-do to Gumi was not an easy one. Yet their unified determination lifted us once again and turned a challenge into opportunity.

These achievements were only possible through the dedication and passion of our employees and their families, who persevered through difficult conditions. I extend my deepest gratitude, especially to those who moved their homes to Gumi and helped build this new beginning with us.

“A CEO’s struggle, heavy sense of responsibility, and weight of guilt”

I regard this relocation as a new starting point, an opportunity for innovation in productivity and quality, for organizational restructuring, and, above all, for renewing ourselves as a company that delivers even greater value to our customers. We are once again creating the foundation for a new leap forward.

With this relocation, COMA Technology will further advance its technological innovation and quality assurance systems, providing even more stable and competitive products. Through continuous R&D investment and production line improvement, we will realize value that exceeds customer expectations and boldly expand into new markets.

As always, I ask for your continued support and encouragement for COMA Technology’s second journey, our ongoing mission to turn the impossible into possible.

Thank you.

Today, with determination that may seem small but carries great weight, I mark the beginning of COMA Technology.

Before us lies a path no one has yet taken, but one that must be walked. With a deep sense of responsibility and resolve, I take this first step forward.

COMA Technology specializes in the precision processing and manufacturing of sapphire products that demand exceptional accuracy and durability. Armed with world-class processing expertise, my vision is to create a technology-driven company that meets every complex customer need, a company that transforms the impossible into possible.

With technology that inspires customers first, trust that draws customers to us first, and the conviction that our customers are our future, I will approach this business with honesty, determination, and persistence.

Before founding COMA Technology, I spent my career as an employee who went beyond merely working with a sense of ownership. I treated the company as truly my own. That mindset drove me to work harder, think deeper, and never give up, even in failure, until every problem was solved. With the same conviction, I aim to build a company where every individual feels genuine ownership and pride in their work.

Our first step may be small, but our dreams are not.

A company that speaks through technology, proves through results, and grows through trust.

We will become a technology-leading company that does more than manufacture parts. We will stand beside our customers, tackle challenges together, confront technical limits head-on, and turn possibility into reality.

The beginning will not be easy. But from the start, we will do things right.

We will take bold action and build a culture that values learning from failure. Through each cycle of challenge and trial, we will grow, and our technology will continue to advance.

I invite you to follow COMA Technology’s journey with your warm support and encouragement.

Thank you.
