Industry & Occupation
Classification
Summary
Job responsible for manufacturing and inspecting photomask originals in the semiconductor manufacturing process.
Description
Photomask original manufacturing workers produce and inspect master plates (photomask originals) for transferring semiconductor circuit patterns in a cleanroom. They perform a series of tasks from reading CAD data, applying resist, operating exposure equipment (steppers or aligners), development, etching, to inspecting fine defects. Important tasks also include setting equipment conditions, adjusting parameters, and process management to improve yield.
Future Outlook
With the increasing demand for semiconductors, the demand for photomask manufacturing technicians will remain stable. The adoption of next-generation technologies such as EUV masks and nanoimprint will increase the value of personnel with advanced specialized knowledge.
