    摘要: A method is disclosed for forming an STI (shallow trench isolation) in a substrate during CMOS (complementary metal-oxide semiconductor) semiconductor fabrication which includes providing at least two wells including dopants. A pad layer may be formed on a top surface of the substrate and a partial STI trench is etched in the upper portion of the substrate followed by etching to form a full STI trench. Boron is implanted in a lower area of the full STI trench forming an implant area which is anodized to form a porous silicon region, which is then oxidized to form a oxidized region. A dielectric layer is formed over the silicon nitride layer filling the full STI trench to provide, after etching, at least two electrical component areas on the top surface of the substrate having the full STI trench therebetween.

    摘要: The present invention provides structures and methods for providing multiple parallel V-shaped faceted grooves with sub-lithographic widths on a semiconductor substrate for enhanced performance MOSFETs. A self-aligning self-assembling material is used to pattern multiple parallel sub-lithographic lines. By employing an anisotropic etch that produces crystallographic facets on a semiconductor surface, multiple adjoining parallel V-shaped grooves with sub-lithographic groove widths are formed. While providing enhanced mobility for the MOSFET, the width of the MOSFET is not limited by the depth of focus in subsequent lithographic steps or the thickness of semiconductor layer above a BOX layer due to the sub-lithographic widths of the V-shaped grooves and the consequent reduction in the variation of the vertical profile. Also, the MOSFET has a well defined threshold voltage due to the narrow widths of each facet.

    摘要: A method is provided of forming contact vias. A dielectric region is formed to overlie substantially all of a transistor structure, the dielectric region having a substantially planar upper surface. A dielectric barrier layer is formed to overlie the upper surface of the dielectric region, the dielectric barrier layer being adapted to substantially prevent diffusion of one or more materials from above the dielectric barrier layer into the dielectric region. A first contact via is formed to extend through the dielectric barrier layer and the dielectric region to provide conductive communication with a conductive member of the transistor structure. A second contact via is formed to extend through the dielectric barrier layer and the dielectric region to provide conductive communication with one of a source region or a drain region of the transistor structure.

    摘要: Disclosed is a method of fabricating a field effect transistor. In the method, a gate stack on a top surface of a semiconductor substrate is formed, and then a first spacer is formed on a sidewall of the gate stack. Next, a silicide self-aligned to the first spacer is deposited in/or on the semiconductor substrate. Subsequently a second spacer covering the surface of the first spacer, and a contact liner over at least the gate stack, the second spacer and the silicide, are formed. Then an interlayer dielectric over the contact liner is deposited. Next, a metal contact opening is formed to expose the contact liner over the silicide. Finally, the opening is extended through the contact liner to expose the silicide without exposing the substrate.

    摘要: Disclosed is a method of forming an integrated circuit structure having first-type transistors, such as P-type field effect transistors (PFETs) and complementary second-type transistors, such as N-type field effect transistors (NFETs) on the same substrate. More specifically, the invention forms gate conductors above channel regions in the substrate, sidewall spacers adjacent the gate conductors, and source and drain extensions in the substrate. The sidewall spacers are larger (extend further from the gate conductor) in the PFETs than in the NFETs. The sidewall spacers align the source and drain extensions during the implanting process. Therefore, the larger sidewall spacers position (align) the source and drain implants further from the channel region for the PFETs when compared to the NFETs. Then, during the subsequent annealing processes, the faster moving PFET impurities will be restrained from diffusing too far into the channel region under the gate conductor. This prevents the short channel effect that occurs when the source and drain impurities extend too far beneath the gate conductor and short out the channel region.
