2.Glass Wafer Process

Wafer Cutting: blank wafer are ready through that thick sheets are water jetted and blocks are wire sawn

Ground Edge: the wafer edge is cylindrical grounded on the Edge Grinding Station.

Wafer Lapping: the wafer is lapped to appointed thickness.

Wafer Polishing: Polishing the wafer gives it the mirrored, super-flat surface required for the fabrication.

Wafer Cleaning: it is the removal of chemical and particle impurities without altering or damaging the wafer surface or substrate on multiple cleaning lines.

Wafer Inspection: inspect to various quality levels under the appropriate lighting condition in the Class 100 Clean Room.

Wafer Packaging: All wafers are packed in the single wafer containers.
