  • Patent number: 7863192
    Abstract: One embodiment relates to a method of fabricating an integrated circuit. In the method, p-type polysilicon is provided over a semiconductor body, where the p-type polysilicon has a first depth as measured from a top surface of the p-type polysilicon. An n-type dopant is implanted into the p-type polysilicon to form a counter-doped layer at the top-surface of the p-type polysilicon, where the counter-doped layer has a second depth that is less than the first depth. A catalyst metal is provided that associates with the counter-doped layer to form a catalytic surface. A metal is deposited over the catalytic surface. A thermal process is performed that reacts the metal with the p-type polysilicon in the presence of the catalytic surface to form a metal silicide. Other methods and devices are also disclosed.

  • Patent number: 7448395
    Abstract: The present invention substantially removes dry etch residue from a dry plasma etch process 110 prior to depositing a cobalt layer 124 on silicon substrate and/or polysilicon material. Subsequently, one or more annealing processes 128 are performed that cause the cobalt to react with the silicon thereby forming cobalt silicide regions. The lack of dry etch residue remaining between the deposited cobalt and the underlying silicon permits the cobalt silicide regions to be formed substantially uniform with a desired silicide sheet and contact resistance. The dry etch residue is substantially removed by performing a first cleaning operation 112 and then an extended cleaning operation 114 that includes a suitable cleaning solution. The first cleaning operation typically removes some, but not all of the dry etch residue. The extended cleaning operation 114 is performed at a higher temperature and/or for an extended duration and substantially removes dry etch residue remaining after the first cleaning operation 112.

  • Patent number: 7422968
    Abstract: The present invention provides a method for manufacturing a semiconductor device, and a method for manufacturing an integrated circuit including the semiconductor devices. The method for manufacturing a semiconductor device (100) , among other steps, includes forming a gate structure (120) over a substrate (110) and forming source/drain regions (190) in the substrate (110) proximate the gate structure (120). The method further includes subjecting the gate structure (120) and substrate (110) to a dry etch process and placing fluorine in the source/drain regions to form fluorinated source/drains (320) subsequent to subjecting the gate structure (120) and substrate (110) to the dry etch process. Thereafter, the method includes forming metal silicide regions (510, 520) in the gate structure (120) and the fluorinated source/drains (320).

  • Publication number: 20050146035
    Abstract: A multilevel metal and via structure is described. The metal conductors include a base or seed layer, a bulk conductor layer, a capping layer, and a barrier layer, and the via structure include a seed layer, a diffusion barrier layer and a metal plug. The via seed layer is controlled to a thickness that discourages the reaction between the via seed layer and the bulk conductor layer. The reaction may result in the formation of harmful voids at the bottom of the vias and is caused by having the via seed metal coming in contact with the bulk conductor through openings in the barrier layer.
