  • Publication number: 20170186882
    Abstract: The present invention is a semiconductor device comprising a semiconducting low doped vertical super-thin body (VSTB) formed on Dielectric Body Wall (such as STI-wall as isolating substrate) having the body connection to bulk semiconductor wafer on the bottom side, isolation on the top side, and the channel, gate dielectric, and gate electrode on opposite to STI side surface. The body is made self-aligned to STI hard mask edge allowing tight control of body thickness. Source and Drain are made by etching holes vertically in STI at STI side of the body and filling with high doped crystalline or poly-Si appropriately doped with any appropriate silicides/metal contacts or with Schottky barrier Source/Drain. Gate first or Gate last approaches can be implemented. Many devices can be fabricated in single active area with body isolation between the devices by iso-plugs combined with gate electrode isolation by iso-trenches.

  • Patent number: 9093311
    Abstract: Techniques for providing a semiconductor memory device are disclosed. In one embodiment, the techniques may be realized as a semiconductor memory device including a plurality of memory cells arranged in an array of rows and columns. Each memory cell may include a first region connected to a source line extending in a first orientation, a second region connected to a bit line extending a second orientation, and a body region spaced apart from and capacitively coupled to a word line, wherein the body region is electrically floating and disposed between the first region and the second region. The semiconductor device may also include a first barrier wall extending in the first orientation of the array and a second barrier wall extending in the second orientation of the array and intersecting with the first barrier wall to form a trench region configured to accommodate each of the plurality of memory cells.
