My job description: We design ozone generators. Our customers are electronics and semiconductor manufacturing equipment manufacturers, both domestic and international. Our ozone generators use discharge energy to generate ozone from oxygen. Ozone is used in the "cleaning" and "film deposition" processes of semiconductor manufacturing. In the "cleaning" process, ozone is dissolved in high-purity water to produce ozone water. In the "film deposition" process, ozone is supplied to the reaction chamber where the wafer is placed to deposit a thin film. Our design work encompasses a wide range of tasks, from creating detailed specifications to reviewing drawings, selecting components, and creating programs. We also handle operation checks, shipping inspections, and maintenance. We work with our client's designers to create products that meet their needs in a near-custom-made manner.
Job satisfaction: My job is rewarding because of the wide range of work I do. I can say that I built the world's highest standard high-concentration ozone generator from scratch! As semiconductors evolve, orders are becoming more difficult, such as "cleaner ozone" and "more compact." How do we make these happen? I have in-depth discussions with the manufacturers who are our clients. Relationships of trust are built through repeated conversations. Even when there's a problem, they say, "We want Mr. K, who built the equipment, to come over." It makes me happy, but it also makes me nervous (laughs). But it feels good to fix the problem and see the equipment working again. I savor the joy that only a creator can have.
Difficulty of the job: Not only is the scope of my work broad, but it's also becoming more difficult every year. This means that I need to acquire a wide range of technical knowledge while also having a deep understanding of cutting-edge technology. Maintenance, in particular, is something I do alone most of the time, so if I don't understand the problem, I can't solve it. When I'm really in trouble, I sometimes call my senior and cry, "Please tell me what to do. Please give me some advice." With each experience like this, I reflect and think, "I should have gained more knowledge." I take it in a positive way, knowing that there are still skills I can acquire! I can grow! I scream with joy, thinking that this is the ultimate reward for being an engineer.

Leave work

Depending on the job, you may have to work overtime. After returning home, you can enjoy time with your family.

The good points of the company: I'm originally from Kanagawa Prefecture. Before joining the company, I was worried about whether I'd be able to keep up with the Kansai vibe, but my worries were unfounded. Everyone here is very friendly and talks to me. I feel like this is especially prevalent at our company. The day after I achieved a good time in a marathon, which is my hobby, someone I hadn't really spoken to before said to me, "I heard you achieved a good time." That comment led to us starting to communicate regularly. It's a company with a lot of friendly people.
