Micrel 6 inch to Microchip 8 inch Fab Transfer

Frequently Asked Questions (FAQ)

Revision 2 – October 1, 2016

Why is Microchip making this change? The Micrel 6 inch

fabrication facility in San Jose is closing. The Microchip 8 inch

fabrication facilities will provide more capacity that will ensure

continuity of supply. Microchip’s fabrication sites have

improved defect control/inspections and more

efficient/diversified fab equipment.
