Devote myself to a semiconductor maker with my major

I discovered USJC when I was studying epitaxial growth, one of the thin-film crystal growth technologies in semiconductor manufacturing, and when I was looking for a job to make the most of what I had learned in my hometown. I heard that semiconductors manufactured by USJC are being used in products such as smartphones and automobiles, and I decided to work for USJC because I thought it would be a good way to work while feeling like I was contributing to society.

Responsible for playing a central role in the manufacturing environment where trial and error are welcomed! Responsible for playing a central role in the manufacturing environment where trial and error is welcomed!

My job is mainly to improve, manage and monitor production lines to make better products faster and at lower cost.
The manufacturing department I belong to is the center of manufacturing, producing semiconductors. Collaboration with other departments is essential for manufacturing. For example, in order to improve product yield, we may review the process of making a product or change the specifications of materials or equipment. We work with process development engineers, customer engineers, and manufacturing facility engineers from other departments to make improvements on a daily basis.
In addition, even though the production line is set up using the same process and equipment as before, it may not go well. In that case, identify the cause of the problem, resolve it, and stabilize the process. I feel a great sense of accomplishment when the product takes shape on the line I launched.

The work environment is very bright and open, and I feel that my opinion is accepted. Incidentally, I studied semiconductors at university, but I definitely learned more after joining the company. Even if you did not major in semiconductors when you were a student, if you are interested in working on your own, your supervisors and seniors will teach you carefully, so you can work in a safe and enjoyable environment.

As a member of "USJC," learn to put yourself in their shoes.

I was passionate about baseball in high school and ice hockey in college, and my motto has always been to act responsibly as a member of a team. Because of this experience, thinking from the other person's point of view, "What would he/she think if I said this?" and "What would he/she do if I did this?
Semiconductor manufacturing involves hundreds to thousands of processes, so it is essential to cooperate with many people, both inside and outside the company, and I feel that my job requires me to think, speak, and act from the perspective of others. Always remember this identity and grow into a person who is responsible as an engineer of "USJC."

Enriching Lives I'm always interested in these tiny chips.

I originally studied electrical and electronic engineering at university. As a student, I focused on experiments, subsequent results, and presentations. While I was looking for a job in electric field, I attended USJC briefing and immediately decided to join the company.
Semiconductors are very small, but they are used in various electronic devices. I was very interested in the fact that they are important components that play a major role in enriching people's lives in the world, such as IoT, 5G, and autonomous driving. In addition, as a member of UMC, a major foundry company that is currently the parent company of USJC even before the business integration, I decided to join USJC because I was attracted to the fact that I could work globally.

Process development covers from A to Z. Process development covers from A to Z.

In short, the main task of the process development department that I belong to is to examine and execute the process of turning what the customer has designed into a product. Process development has two main roles, one is to develop elemental technologies for the minimum basic unit that constitutes a semiconductor manufacturing process (e.g.,deposition, lithography, etching, CMP, cleaning, etc.), and the other is to develop integration technologies for forming integrated circuits on wafers by combining these elemental technologies. I am in charge of process development for thin film formation technology, which is elemental technology development. I work with those in charge of each process and integration to examine processing methods, and when required to investigate a problem, I investigate the cause and resolve it.
Specifically, a problem with increasing defects occurred in my project, and the person in charge of integration asked me to investigate the cause. Because the processes I am in charge of are intertwined with various processes, it is really difficult to determine when and in which process the cause occurs. There are many cases where my knowledge is not enough to know which approach to take, so I consult with my superiors and seniors and conduct experiments with advice. By examining the data and repeatedly consulting with my superiors and seniors, I identify the cause and consider improvement ideas. Then, in order to apply improvement ideas, I discuss them again with the person in charge of the relevant department, including quality control, and try to solve the problem by examining the effect and the risk impact on other processes.
However, there are few things that I can solve by myself, so I consult with my supervisors and seniors and get advice on how to improve things. Because it is necessary to discuss with each other as we proceed with our work, communication naturally increases, and the company culture is warm and welcoming.

I had grown into a "reliable senior."

I try to take notes on advice from my supervisors and seniors consistently since I joined the company. The reason is that technology is evolving every day in the semiconductor industry, but I often feel that the advice from my supervisors and seniors is just the history of semiconductor technology.
I keep such valuable advice as notes as I go about my daily work and feel that I am growing.
Also, my supervisors and seniors have been warmly watching my growth while teaching me in a clear and respectful manner since I joined the company, even though I did not major in semiconductors. In the future, I will step up to become a "reliable senior" who can pass on the historic technology I have inherited from my supervisors and seniors.
