摘要:
A semiconductor structure and method of manufacturing a semiconductor device, and more particularly, an NFET device. The devices includes a stress receiving layer provided over a stress inducing layer with a material at an interface there between which reduces the occurrence and propagation of misfit dislocations in the structure. The stress receiving layer is silicon (Si), the stress inducing layer is silicon-germanium (SiGe) and the material is carbon which is provided by doping the layers during formation of the device. The carbon can be doped throughout the whole of the SiGe layer also.

The invention relates to a semiconductor structure and method of manufacturing and more particularly to a CMOS device with a stress inducing material embedded in both gates and also in the source/drain region of the PFET and varying thickness of the PFET and NFET channel. In one embodiment, the structure enhances the device performance by varying the thickness of the top Silicon layer respective to the NFET or the PFET.

A method and apparatus is provided for fabricating a damascene interconnection. The method begins by forming on a substrate an organosilicate dielectric layer, a capping layer on the organosilicate dielectric layer, and a resist pattern over the capping layer to define a first interconnect opening. The capping layer is etched through the resist pattern using a first etchant. The resist pattern is removed after etching the capping layer. The dielectric layer is etched through the capping layer using a second etchant different from the first etchant to form the first interconnect opening. An interconnection is completed by filling the first interconnect opening with conductive material.

Device structure embodied in a machine readable medium for designing, manufacturing, or testing a design. The design structure includes a gate electrode of a device, such as a field effect transistor, having an air gap or void disposed adjacent to a sidewall of the gate electrode. The void may be bounded by a dielectric spacer proximate to the sidewall of the gate electrode and a dielectric layer having a spaced relationship with the dielectric spacer.

A process for preparing an electronics structure involves coating a substrate stack with a sacrificial multilayer hardmask stack, developing a pattern in a resist layer coated on a topmost layer of the multilayer hardmask stack, transferring the pattern into the hardmask stack, blocking a portion of the pattern, and then transferring an unblocked portion of the pattern into the substrate stack. Electronics structures prepared with the process are useful to prepare electronics devices, such as computers and the like.
