  • Patent number: 10056395
    Abstract: A method of manufacturing an integrated circuit including forming trenches into the surface of a crystalline wafer and the trenches extending along a <100> lattice direction is disclosed. Such wafer can experience less deformation due to less stress induced when the trenches are filled using a spin-on dielectric material. Thus, the overlay issue caused by wafer shape change is resolved.

  • Patent number: 9337208
    Abstract: A method of manufacturing a semiconductor device is provided. Gate structures are formed on a substrate, and a first dielectric layer having grooves is formed between two adjacent gate structures. An upper surface of the first dielectric layer is lower than an upper surface of the gate structures. Afterwards, an intermediate layer is formed to cover the gate structures, the first dielectric layer, and the grooves, and openings are formed therein. Each opening is formed between two adjacent gate structures, and the first dielectric layer is removed through the opening. Next, a second dielectric layer is formed on the intermediate layer, so as to define an air gap between two adjacent gate structures. Furthermore, a semiconductor device is provided.

  • Publication number: 20150187578
    Abstract: A method of manufacturing a flash memory is provided. In the method, a hydrogen treatment is performed on a substrate, on which a polysilicon gate and a plurality of spacers on sidewalls of the polysilicon gate are formed. A silicon thin film is deposited on the polysilicon gate to extend a top area thereof. The hydrogen treatment and the deposition of the silicon thin film are accomplished repeatedly, and then a cobalt layer is deposited on the silicon thin film. A portion of the cobalt layer is converted to a CoSix layer, and the unreacted cobalt layer is then removed.
