Statistical Process Controls (SPC) er en metode brug af to overvågning og kontrol fabrikationsprocesser. In halvvejs fabrikation, SPC hjælper identify variations that ap to afhops, muliggøre ling proaktive justeringer to forbedring kvalitet og give.

Implementering af SPC i halvledere Fremstillingsvirksomhed

Implementing SPC involverer collectin data from varios stags other fabricatio proces. This data is analyzed using control charts to detect trends or divertions. Early detektio allows satis to addresses issues befor e receits concess, reductin whe and d rework.

Case Example: Defect Reduction through SPC

En halvvejs plan implementeres SPC across kritiske processer trin. By monitoring ing key parameters with control charts, the team identified a drift in etching interesty. Rettelse handling er take take-in prompt, result in a 30% reduction it 's repour rate is secret six months.
