Industry & Occupation
Classification
Summary
Manufacturing operator responsible for the production process of phototransistor elements in a cleanroom, performing equipment operation and quality inspection.
Description
Phototransistor manufacturing workers are professionals who carry out the manufacturing processes of phototransistors using semiconductor wafers in cleanrooms. They handle equipment operation for each process, process condition settings, sample measurements, and defect inspections, from front-end processes such as cleaning, etching, photolithography, ion implantation, thin film deposition, and CMP, to back-end processes such as dicing, wire bonding, and packaging. They also perform daily equipment inspections and cleaning, propose process improvements, record and analyze quality data, and teamwork is required to maintain high yields.
Future Outlook
With the expansion of the semiconductor market, the expertise of phototransistor manufacturing workers will continue to be in demand. While automation and AI utilization advance, the demand for skilled technicians who handle finer processes, new material processes, and yield improvements remains high.
