Design | Ozone Generator

As the creator of the device, I take responsibility for every step of the process.: T.K Joined in 2016

#Joined the company as a new graduate
Engineering Positions positions

My job description: We design ozone generators. Our customers for these devices are electronics manufacturers and semiconductor manufacturing equipment manufacturers, both domestically and internationally. Our ozone generators generate ozone from oxygen using discharge energy. In semiconductor manufacturing processes, ozone is used for "cleaning" and "Deposition." In the "cleaning" process, it is dissolved in high-purity water and used as ozonated water. In the "Deposition" process, it is supplied to the reaction chamber where wafers are placed and used to deposit thin films. Our design responsibilities are very broad, starting with creating detailed specifications, checking drawings, selecting components, creating programs, and also involving operational checks, shipping Inspection, and maintenance. We meet with the designers of our customer manufacturers to create products that meet their needs in a near-customized manner.
Job satisfaction: What I find rewarding is the wide range of responsibilities I have. I can say that I built a world-class high-concentration ozone generator from scratch! As semiconductors evolve, the difficulty of orders increases, such as "cleaner ozone" and "more compact." How do we make that happen? I have in-depth discussions with the manufacturer's representatives, who are our customers. Trust is built through repeated conversations. When there are problems, they even say, "We want Mr. K, who built the device, to come and help." It's gratifying, but also nerve-wracking (laughs). But it feels good to fix Fault and see it working again. I savor the joy that only the creator can experience.
The difficulty of the job: My job responsibilities are broad, and the difficulty level increases year after year. This means I need to acquire broad technical knowledge while also having a deep understanding of cutting-edge technologies. Especially with maintenance, I'm usually working alone, so if I don't know the answer, I can't solve the problem. There have been times when I've been really stuck and called a senior colleague, pleading, "Please give me some advice on what to do." Every time I have an experience like that, I regret not having acquired more knowledge. But I try to take it positively, thinking, "There are still so many skills I can acquire! I can grow!" I'm happy to be a skilled engineer, and I'm overwhelmed with joy.

Leaving the company

Depending on the job, there may be overtime. After returning home, enjoy quality time with family.

The good points of the company: I'm from Kanagawa Prefecture. Before joining the company, I was worried about whether I could keep up with the Kansai style of communication, but my worries were unfounded. Everyone is very friendly and easy to talk to. I feel that this is especially true at our company. The day after I achieved a good time in my hobby of marathon running, someone I hadn't talked to much before approached me and said, "I heard you got a good time." That one comment sparked a new friendship, and we've been communicating regularly ever since. This company is full of friendly people.
