  • Publication number: 20230145089
    Abstract: Embodiments disclosed herein include semiconductor devices and methods of forming such semiconductor devices. In an embodiment, a method of fabricating a semiconductor device comprises, forming a first grating of parallel first lines, forming a second grating of parallel second lines, wherein the second lines are substantially orthogonal to the first lines, and wherein the first lines and second lines define a plurality of first openings, disposing a conformal mask layer over the first lines and the second lines, wherein the conformal mask layer partially fills the first openings and defines a second opening within each of the first openings, disposing a hardmask over the conformal mask layer, wherein the hardmask fills the second openings, patterning third openings into the hardmask, wherein the third openings clear the hardmask from at least one of the second openings, and removing the mask layer proximate to cleared second openings to clear first openings.
    Type: Application

  • Patent number: 9935205
    Abstract: A nanowire transistor of the present description may be produced with internal spacers formed by using sacrificial spacers during the fabrication thereof. Once the nanowire transistor is formed, the sacrificial spacers, which are position between the transistor gate and the source and drains (respectively), may be removed. The sacrificial material between channel nanowires of the nanowire transistor may then be removed and a dielectric material may be deposited to fill the spaces between the channel nanowires. The dielectric material not between the channel nanowires may be removed to form the internal spacers. External spacers, which are position between the transistor gate and the source and drains (respectively), may then be formed adjacent the internal spacers and transistor channel nanowires.
