发明名称 Semiconductor Device Structure With 110-PFET and 111-NFET Current Flow Direction
摘要 A FinFET comprises a hybrid substrate having a top wafer of (100) silicon, a handle wafer of (110) silicon, and a buried oxide layer between the top wafer and the handle wafer; a first set of fins disposed in the top wafer and oriented in a <110> direction of the (100) silicon; and a second set of fins disposed in the handle wafer and oriented in a <112> direction of the (110) silicon. The first set of fins and the second set of fins are aligned.

主权项 1. A method, comprising: forming a substrate comprising a top wafer of (100) silicon, a handle wafer of (110) silicon, and a buried oxide layer between the top wafer and the handle wafer, wherein the top wafer and the handle wafer are arranged such that a <110> direction of the (100) silicon of the top wafer aligns with a <112> direction of the (110) silicon of the handle wafer; forming trenches in the top wafer; forming trenches through the top wafer and into the handle wafer; and disposing fins in the trenches.
