Abstract
An integrated circuit is described that comprises a PMOS transistor and an NMOS transistor that are formed on a semiconductor substrate. A silicate glass layer is formed on only the PMOS transistor or the NMOS transistor; and an etch stop layer is formed on the silicate glass layer. Also described is a method for forming an integrated circuit. That method comprises forming a PMOS transistor structure and an NMOS transistor structure on a semiconductor substrate, forming a silicate glass layer on only the PMOS transistor structure or the NMOS transistor structure, and forming an etch stop layer on the silicate glass layer.
