Industry & Occupation
Classification
Summary
Manufacturing operator who forms fine patterns on semiconductor wafers through chemical and physical etching processes.
Description
Semiconductor etching workers operate dry etching or wet etching equipment based on resist patterns formed by photolithography to remove unnecessary parts and form circuit patterns. The primary work is in cleanrooms, involving adjustment of process parameters (such as gas flow, pressure, and time), equipment maintenance, periodic equipment calibration, and in-process quality inspections (CD measurement and defect inspection). When product defects or abnormalities occur, they analyze the causes and implement appropriate countermeasures. Safety management and chemical handling are also important parts of the job.
Future Outlook
With the growth of the semiconductor market, miniaturization technologies are advancing, and demand for etching processes remains stable. As automation and AI technologies advance, the value of workers skilled in equipment control and data analysis will increase.
