发明名称 Methods of forming CMOS transistors using tensile stress layers and hydrogen plasma treatment
摘要 Methods of forming integrated circuit devices include forming a PMOS transistor having a SiGe channel region therein and then exposing at least a portion of the PMOS transistor to a hydrogen plasma. A tensile stress layer may be formed on the PMOS transistor. The exposing step may include exposing source and drain regions of the PMOS transistor to the hydrogen plasma.

主权项 1. A method of forming an integrated circuit device, comprising: forming a PMOS transistor having a SiGe channel region therein, said forming a PMOS transistor comprising adjusting a position of a substrate such that a crystallographic orientation of the SiGe channel region formed in the substrate is parallel to a <100> crystallographic orientation of the substrate; exposing source and drain regions of the PMOS transistor to a hydrogen plasma; and forming a tensile stress layer on the PMOS transistor, which applies tensile stress to the SiGe channel region, after said exposing.
