VIRTUAL WAFER TECHNIQUES FOR FABRICATING SEMICONDUCTOR DEVICES

VIRTUAL WAFER TECHNIQUES FOR FABRICATING SEMICONDUCTOR DEVICES

A method of fabricating semiconductor devices including epitaxially depositing a heavily doped substrate layer that is substantially free of crystalline defects on a lightly doped virtual substrate. The device regions of the semiconductor devices can be fabricated about the heavily doped substrate l...

Zusammenfassung:A method of fabricating semiconductor devices including epitaxially depositing a heavily doped substrate layer that is substantially free of crystalline defects on a lightly doped virtual substrate. The device regions of the semiconductor devices can be fabricated about the heavily doped substrate layer before the lightly doped virtual substrate is removed.
