Abstract:
Methods of forming an electrically conductive path under a barrier oxide layer of a semiconductor-on-insulator (SOI) substrate and an integrated circuit including the path are disclosed. In one embodiment, the method includes forming an electrically conductive path below a barrier oxide layer of a semiconductor-on-insulator (SOI) substrate, the method comprising: forming a first barrier oxide layer on a semiconductor substrate; forming the electrically conductive path within the first barrier oxide layer; and forming a second barrier oxide layer on the first barrier oxide layer. The electrically conductive path allows reduction of SRAM area by forming a wiring path underneath the barrier oxide layer on the SOI substrate.
