  • Patent number: 10879272
    Abstract: A semiconductor device production system using a laser crystallization method is provided which can avoid forming grain boundaries in a channel formation region of a TFT, thereby preventing grain boundaries from lowering the mobility of the TFT greatly, from lowering ON current, and from increasing OFF current. Rectangular or stripe pattern depression and projection portions are formed on an insulating film. A semiconductor film is formed on the insulating film. The semiconductor film is irradiated with continuous wave laser light by running the laser light along the stripe pattern depression and projection portions of the insulating film or along the major or minor axis direction of the rectangle. Although continuous wave laser light is most preferred among laser light, it is also possible to use pulse oscillation laser light in irradiating the semiconductor film.

  • Patent number: 10879180
    Abstract: In the manufacture of a FinFET device, an isolation architecture is provided between gate and source/drain contact locations. The isolation architecture may include a low-k spacer layer and a contact etch stop layer. An upper portion of the isolation architecture is removed and replaced with a high-k, etch-selective spacer layer adapted to resist degradation during an etch to open the source/drain contact locations. The high-k spacer layer, in conjunction with a self-aligned contact (SAC) capping layer disposed over the gate and overlapping a sidewall of the isolation layer, forms an improved isolation structure that inhibits short circuits or parasitic capacitance between the gate and source/drain contacts.
