Abstract:
1. An integrated circuit device, comprising: a hybrid orientation substrate including an upper layer having a top surface with a first crystal orientation directly bonded over a lower substrate having a top surface with a second crystal orientation; a recrystallized region of the upper layer having the second crystal orientation of the lower substrate and being patterned into a form of a first fin having a top surface with the second crystal orientation and a sidewall surface with the first crystal orientation; and another region of the upper layer patterned into a form of a second fin having a top surface with the first crystal orientation and a sidewall surface with the second crystal orientation; the first fin sidewall surface defining a channel with a first carrier flow direction of a first FinFET, the second fin sidewall defining a channel with a second carrier flow direction of a second FinFET, and the second carrier flow direction being parallel or perpendicular to the first carrier flow direction.
