    摘要: Hybrid orientation technology (HOT) substrates for CMOS ICs include (100)-oriented silicon regions for NMOS and (110) regions for PMOS for optimizing carrier mobilities in the respective MOS transistors. Boundary regions between (100) and (110) regions must be sufficiently narrow to support high gate densities and SRAM cells. This invention provides a method of forming a HOT substrate containing regions with two different silicon crystal lattice orientations, with boundary morphology less than 40 nanometers wide. Starting with a direct silicon bonded (DSB) wafer of a (100) substrate wafer and a (110) DBS layer, NMOS regions in the DSB layer are amorphized by a double implant and recrystallized on a (100) orientation by solid phase epitaxy (SPE). Crystal defects during anneal are prevented by a low temperature oxide layer on the top surface of the wafer. An integrated circuit formed with the inventive method is also disclosed.

    摘要: Dopants are implanted at relatively high energies into an unmasked first region of a semiconductor substrate through a thin layer of gate electrode material and a gate dielectric layer. Lower energy dopants are then implanted into the thin layer of gate electrode material. The first region is then masked off, and the process is repeated in a previously masked, but now unmasked, second region of the semiconductor substrate. A second (and usually thicker) layer of gate electrode material is then formed over the thin layer of gate electrode material. The layer of thick gate electrode material, the layer of thin gate electrode material and the layer of gate dielectric material are patterned to form one or more gate structures over the doped regions of the substrate. Source and drain regions are formed in the substrate regions adjacent to the gate structures to establish one or more MOS transistors.

    摘要: An integrated circuit includes one or more transistors on or in a semiconductor substrate. At least one of the transistors includes a gate electrode and source and drain structures. The gate electrode has a fully silicided gate electrode layer with a ratio of Ni:Si ranging from about 2:1 to about 3:1. The source and drain structures are located in openings of the substrate and adjacent to the gate electrode. The source and drain structures are filled with SiGe to produce stress in the transistor channel region.

    摘要: An integrated circuit is disclosed having symmetric and asymmetric MOS transistors of the same polarity, oriented perpendicularly to each other, formed by concurrent halo ion, LDD ion and/or S/D ion implant processes using angled, rotated sub-implants which vary the tilt angle, dose and/or energy between rotations. Implanted halo, LDD and/or S/D source and drain regions formed by angled subimplants may have different extents of overlap with, or lateral separation from, gates of the two types of transistors, producing transistors with two different sets of electrical properties. A process for concurrently fabricating the two types of transistors is also disclosed. Specific embodiments of processes for concurrently forming symmetric and asymmetric transistors are disclosed.
