  • Patent number: 9012282
    Abstract: A self-align method of preparing semiconductor gates for formation of a silicide, such as a cobalt silicide (CoSi) layer, is disclosed. Deposition of silicon nitride (SiN) and low-temperature oxide (LTO) liner types, the SiN liner having an overhang structure, prevent damage to the gates while forming a self-aligned source. The undamaged gates are suitable for CoSi deposition.

  • Patent number: 7202493
    Abstract: A chalcogenide phase change memory cell has a substrate with a conductor line. The conductor line has a contact end. An insulating layer is located over the substrate and conductor line. An aperture is located in the insulating layer. The aperture extends to the substrate. A memory material is conformally located within the aperture. The memory material is in electrical contact with the contact end. A conductive layer is located over the memory material in the aperture.

  • Patent number: 6551879
    Abstract: A method for forming a semiconductor device that includes defining a substrate to include a peripheral section and a core section, masking the peripheral section of the substrate, growing a first dielectric layer over the core section of the substrate, depositing a first polysilicon layer over the first dielectric layer for forming at least one gate structure, growing a first oxide layer over the first polysilicon layer, depositing a nitride layer over the first oxide layer, implanting oxygen ions into the nitride layer, unmasking the peripheral section of the substrate, and growing a second oxide layer over the nitride layer, wherein the growth rate of the second oxide layer is increased due to the implantation of oxygen ions in the nitride layer.

  • Patent number: 6506688
    Abstract: A method for removing a photoresist layer on wafer edge is disclosed. The invention uses a light source located under a spin on coated wafer mounted on a supporting mean of a rotatable chuck to expose the photoresist material on the wafer edge. First of all, the spin on coated wafer is mounted on the supporting mean of the rotatable chuck. Then the rotatable chuck is rotated and the wafer is exposed to the light source. Finally, the wafer is developed.
