摘要： The present invention provides an interconnect structure (of the single or dual damascene type) and a method of forming the same, in which a dense (i.e., non-porous) dielectric spacer is present on the sidewalls of a dielectric material. More specifically, the inventive structure includes a dielectric material having a conductive material embedded within at least one opening in the dielectric material, wherein the conductive material is laterally spaced apart from the dielectric material by a diffusion barrier, a dense dielectric spacer and, optionally, an air gap. The presence of the dense dielectric spacer results in a hybrid interconnect structure that has improved reliability and performance as compared with existing prior art interconnect structures which do not include such dense dielectric spacers. Moreover, the inventive hybrid interconnect structure provides for better process control which leads to the potential for high volume manufacturing.

摘要： The present invention provides an improved CMOS diode structure with dual gate conductors. Specifically, a substrate comprising a first n-doped region and a second p-doped region is formed. A third region of either n-type or p-type conductivity is located between the first and second regions. A first gate conductor of n-type conductivity and a second gate conductor of p-type conductivity are located over the substrate and adjacent to the first and second regions, respectively. Further, the second gate conductor is spaced apart and isolated from the first gate conductor by a dielectric isolation structure. An accumulation region with an underlying depletion region can be formed in such a diode structure between the third region and the second or the first region, and such an accumulation region preferably has a width that is positively correlated with that of the second or the first gate conductor.

摘要： A method of manufacturing complementary metal oxide semiconductor transistors forms different types of transistors such as N-type metal oxide semiconductor (NMOS) transistors and P-type metal oxide semiconductor (PMOS) transistors (first and second type transistors) on a substrate (12). The method forms an optional oxide layer (52) on the NMOS transistors and the PMOS transistors and then covers the NMOS transistors and the PMOS transistors with a hard material (50) such as a silicon nitride layer. Following this, the method patterns portions of the hard material layer (50), such that the hard material layer remains only over the NMOS transistors. Next, the method heats (178, 204) the NMOS transistors and then removes the remaining portions of the hard material layer (50). By creating compressive stress in the gates (22) and tensile stress (70) in the channel regions of the NMOS transistors (NFETs), without creating stress in the gates (20) or channel regions of the PMOS transistors (PFETs), the method improves performance of the NFETs without degrading performance of the PFETs.

摘要： A method for manufacturing a device including an n-type device and a p-type device. In an aspect of the invention, the method involves doping a portion of a semiconductor substrate (200) and forming a gap (219) in the semiconductor substrate (200) by removing at least a portion of the doped portion of the semiconductor substrate (200).

摘要： A semiconductor structure of strained MOSFETs, comprising both PMOSFETs and NMOSFETS, and a method for fabricating strained MOSFETs are disclosed that optimize strain in the MOSFETs, and more particularly maximize the strain in one kind (P or N) of MOSFET and minimize and relax the strain in another kind (N or P) of MOSFET, A strain inducing CA nitride coating having an original full thickness is formed over both the PMOSFETs and the NMOSFETs, wherein the strain inducing coating produces an optimized full strain in one kind of semiconductor device and degrades the performance of the other kind of semiconductor device. The strain inducing CA nitride coating is etched to a reduced thickness over the other kind of semiconductor devices, wherein the reduced thickness of the strain inducing coating relaxes and produces less strain in the other MOSFETs.
