Hard Skills
IntermediatePhotoresist Coating ApplicationThe ability to apply a uniform layer of light-sensitive material to printed circuit boards or semiconductor wafers using techniques like spin coating or spray coating.
IntermediateUV Exposure CalibrationSetting and managing ultraviolet light intensity and exposure duration to transfer circuit patterns from a mask to the photoresist layer.
IntermediatePhotolithographic InspectionUtilizing microscopes and automated optical inspection (AOI) tools to detect defects like pinholes, bridges, or pattern misalignment in the photoresist.
FoundationalHazardous Chemical HandlingThe safe usage, storage, and disposal of developers, solvents, and photoresist chemicals in accordance with Safety Data Sheets (SDS).
FoundationalCleanroom Protocol AdherenceStrict compliance with environmental controls, gowning procedures, and contamination prevention measures to maintain air purity levels.
IntermediateTechnical Drawing InterpretationReading and understanding circuit layout blueprints and technical specifications to ensure correct alignment and orientation of patterns.
