    摘要: A method patterns pairs of semiconducting fins on an insulator layer and then patterns a linear gate conductor structure over and perpendicular to the fins. Next, the method patterns a mask on the insulator layer adjacent the fins such that sidewalls of the mask are parallel to the fins and are spaced from the fins a predetermined distance. The method performs an angled impurity implant into regions of the fins not protected by the gate conductor structure and the mask. This process forms impurity concentrations within the fins that are asymmetric and that mirror one another in adjacent pairs of fins.

    摘要: A low power maskless inter-well deep trench isolation structure and methods of manufacture such structure are provided. A method includes depositing a plurality of layers over a substrate, and forming a layer over the plurality of layers. The method also includes forming well structures in the substrate, and forming sidewall spacers at opposing sides of the layer. The method further includes forming a self-aligned deep trench in the substrate to below the well structures, by removing the sidewall spacers and portions of the substrate aligned with an opening formed by the removal of the sidewall spacers. The method also includes forming a shallow trench in alignment with the deep trench. The method further includes forming shallow trench isolation structures and deep trench isolation structures by filling the shallow trench and the deep trench with insulator material.

    摘要: Methods for fabricating dual-depth trench isolation regions for a memory cell. First and second deep trench isolation regions are formed in the semiconductor layer that laterally bound a device region in a well of a first conductivity type in the semiconductor layer. First and second pluralities of doped regions of a second conductivity type are formed in the device region. A shallow trench isolation region is formed that extends laterally across the device region from the first deep trench isolation region to the second deep trench isolation region. The shallow trench isolation region is disposed in the device region between the first and second pluralities of doped regions. The shallow trench isolation region extends into the semiconductor layer to a depth such that the well is continuous beneath the shallow trench isolation region. A gate stack controls carrier flow between a pair of the first plurality of doped regions.

    摘要: A high density, asymmetric, butted junction CMOS inverter, formed on an SOI substrate, may include: an asymmetric p-FET that includes a halo implant on only a source side of the p-FET; an asymmetric n-FET that includes a halo implant on only a source side of the n-FET; and a butted junction comprising an area of said SOI substrate where a drain region of the asymmetric n-FET and a drain region of the asymmetric p-FET are in direct physical contact. Asymmetric halo implants may be formed by a sequential process of covering a first FET of the CMOS inverter with an ion-absorbing structure and applying angled ion radiation to only the source side of the second FET, removing the ion-absorbing structure, covering the first FET with a second ion-absorbing structure, and applying angled ion radiation to only the source side of the second FET. A layout display of CMOS integrated circuit may require one ground rule for the high density, asymmetric butted junction CMOS inverter and another ground rule for other CMOS circuits.
