  • Publication number: 20070052002
    Abstract: A memory device includes a substrate and source and drain regions formed in the substrate. The source and drain regions include both phosphorous and arsenic and the phosphorous may be implanted prior to the arsenic. The memory device also includes a first dielectric layer formed over the substrate and a charge storage element formed over the first dielectric layer. The memory device may further include a second dielectric layer formed over the charge storage element and a control gate formed over the second dielectric layer.

  • Publication number: 20050153492
    Abstract: A method of forming a fin field effect transistor includes forming a fin and forming a source region adjacent a first end of the fin and a drain region adjacent a second end of the fin. The method further includes forming a dummy gate over the fin and forming a dielectric layer around the dummy gate. The method also includes removing the dummy gate to form a trench in the dielectric layer and forming a metal gate in the trench.

  • Publication number: 20050153485
    Abstract: A method of forming a fin field effect transistor includes forming a fin and forming a source region on a first end of the fin and a drain region on a second end of the fin. The method further includes forming a dummy gate with a first semi-conducting material in a first pattern over the fin and forming a dielectric layer around the dummy gate. The method also includes removing the first semi-conducting material to leave a trench in the dielectric layer corresponding to the first pattern, thinning a portion of the fin exposed within the trench, and forming a metal gate within the trench.

  • Publication number: 20050118824
    Abstract: A method of manufacturing a MOSFET type semiconductor device includes planarizing a gate material layer that is deposited over a channel. The planarization is performed in a multi-step process that includes an initial “rough” planarization and then a “fine” planarization. The slurry used for the finer planarization may include added material that tends to adhere to low areas of the gate material.

  • Publication number: 20050104091
    Abstract: A method for forming a metal-oxide semiconductor field-effect transistor (MOSFET) includes patterning a fin area, a source region, and a drain region on a substrate, forming a fin in the fin area, and forming a mask in the fin area. The method further includes etching the mask to expose a channel area of the MOSFET, etching the fin to thin a width of the fin in the channel area, forming a gate over the fin, and forming contacts to the gate, the source region, and the drain region.

  • Publication number: 20050056845
    Abstract: A FinFET-type semiconductor device includes a fin structure on which a relatively thin amorphous silicon layer and then an undoped polysilicon layer is formed. The semiconductor device may be planarized using a chemical mechanical polishing (CMP) in which the amorphous silicon layer acts as a stop layer to prevent damage to the fin structure.

  • Publication number: 20050029603
    Abstract: A semiconductor device may include a substrate and an insulating layer formed on the substrate. A first device may be formed on the insulating layer, including a first fin. The first fin may be formed on the insulating layer and may have a first fin aspect ratio. A second device may be formed on the insulating layer, including a second fin. The second fin may be formed on the insulating layer and may have a second fin aspect ratio different from the first fin aspect ratio.

  • Publication number: 20050006666
    Abstract: A method of forming a semiconductor device includes forming a fin on an insulating layer, where the fin includes a number of side surfaces, a top surface and a bottom surface. The method also includes forming a gate on the insulating layer, where the gate has a substantially U-shaped cross-section at a channel region of the semiconductor device.
