Replacement Metal Gate Structures

International Business Machines Corporation

A patent family: one line of work, grouped by real continuity rather than by a technology label inferred from titles. 16 of these applications claim priority to application 14/667,085, filed Mar 24, 2015. 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.
