I-PEX plays a leading role in world-class technology, having achieved the world's first PZT single-crystal thin film by optimizing plasma control, film composition, and other factors. As a result, we have attained excellent voltage performance, a low dielectric constant, improved heat resistance (covering a wide range of operating temperatures), and polarization formation during film deposition. The successful candidate will be responsible for the development of MEMS processes, including photolithography, etching, protective film deposition, and all related technical work, such as the examination of deposition processes (creation of conditions), flow, characteristic evaluation, and more. This will occur during the customization stage and transition to mass production based on our high-functional materials. In some cases, you may be required to step outside the chain of command and use research facilities, such as those at universities, for process development. To customize the process according to customer needs, you will work closely with the sales department to address customer requests.
