Semiconductor Device with Low-Conducting Buried And/Or Surface Layers

Sensor Electronic Technology, Inc.

A patent family: one line of work, grouped by real continuity rather than by a technology label inferred from titles. 4 of these applications claim priority to application 61/561,989, filed Nov 21, 2011. A shared origin can cover several different claimed inventions, which is why members here may not share a title. In-force patents first, soonest term end first, then patent number. Expired patents follow, in the same order.
