  • Patent number: 7057237
    Abstract: A method is described for forming three or more spacer widths in transistor regions on a substrate. In one embodiment, different silicon nitride thicknesses are formed above gate electrodes followed by nitride etching to form spacers. Optionally, different gate electrode thicknesses may be fabricated and a conformal oxide layer is deposited which is subsequently etched to form different oxide spacer widths. A third embodiment involves a combination of different gate electrode thickness and different nitride thicknesses. A fourth embodiment involves selectively thinning an oxide layer over certain gate electrodes before etching to form spacers. Therefore, spacer widths can be independently optimized for different transistor regions on a substrate to enable better drive current in transistors with narrow spacers and improved SCE control in neighboring transistors with wider spacers. Better drive current is also obtained in transistors with shorter polysilicon thickness.

  • Patent number: 7005236
    Abstract: Maintaining photoresist thickness and uniformity over a substrate that includes various cavities presents problems, such as preventing distortion of features in the resist image close to cavity edges. These problems have been overcome by laying down the photoresist as two separate layers. The first layer is used to eliminate or reduce problems associated with the presence of the cavities. The second layer is processed in the normal way and does not introduce distortions close to a cavity's edge. A first embodiment introduces some liquid into the cavity before laying down the first layer while the second embodiment etches away part of the first layer before applying the second one. Application of the process to the formation of a cantilever that overhangs a cavity is also described.

Likewise, the second cascode current mirror includes a second output mirror transistor and a second output cascode transistor. The second switching transistor is interposed between the second output mirror and the second output cascode transistors. During assertion of a second control signal, the second switching transistor is turned on so the second mirror current can flow through the output node.

  • Publication number: 20060009001
    Abstract: Abstract of the Disclosure A method of forming a channel region for a MOSFET device in a strained silicon layer via employment of adjacent and surrounding silicon-germanium shapes, has been developed. The method features simultaneous formation of recesses in a top portion of a conductive gate structure and in portions of the semiconductor substrate not occupied by the gate structure or by dummy spacers located on the sides of the conductive gate structure. The selectively defined recesses will be used to subsequently accommodate silicon-germanium shapes, with the silicon-germanium shapes located in the recesses in the semiconductor substrate inducing the desired strained channel region. The recessing of the conductive gate structure and of semiconductor substrate portion reduces the risk of silicon-germanium bridging across the surface of sidewall spacers during epitaxial growth of the alloy layer, thus reducing the risk of gate to substrate leakage or shorts.

  • Publication number: 20050272188
    Abstract: A method of fabricating a CMOS device wherein mobility enhancement of both the NMOS and PMOS elements is realized via strain induced band structure modification, has been developed. The NMOS element is formed featuring a silicon channel region under biaxial strain while the PMOS element is simultaneously formed featuring a SiGe channel region under biaxial compressive strain. A novel process sequence allowing formation of a thicker silicon layer overlying a SiGe layer, allows the NMOS channel region to exist in the silicon layer overlying a SiGe layer, allows the NMOS channel region to exist in the silicon layer which is under biaxial tensile strain enhancing electron mobility. The same novel process sequence results in the presence of a thinner silicon layer, overlying the same SiGe layer in the PMOS region, allowing the PMOS channel region to exist in the biaxial compressively strained SiGe layer, resulting in hole mobility enhancement.
