Abstract: Deep profile and highly doped impurity regions can be formed by diffusing from a solid source or doped silicon glass and using a patterned nitride layer. An oxide etch stop and polysilicon sacrificial layer are left in place in the patterned regions and the dopant is diffused through those layers. The polysilicon provides sacrificial silicon that serves to prevent the formation of boron silicon nitride on the substrate surface and also protects the oxide layer during etching of the silicon glass layer. The oxide layer then acts as an etch stop during removal of the polysilicon layer. In this way, no damage done to the substrate surface during the diffusion or subsequent etch steps and the need for expensive ion implanter steps is avoided.

Abstract: A high impedance load for an integrated circuit device provides an undoped, or lightly doped, layer of epitaxial silicon. The epitaxial silicon layer is formed over a conductive region in a substrate, such as a source/drain region. A highly conductive contact, such as a refractory metal silicide interconnect layer, is formed on top of the epitaxial silicon layer. Preferably, the epitaxial silicon layer is formed using solid phase epitaxy, from excess silicon in the silicide layer, by annealing the device after the silicide layer has been deposited.

Abstract: A method is provided for a planar surface of a semiconductor integrated circuit, and an integrated circuit formed according to the same. A conductive layer is formed over a substrate. A silicon nitride layer is formed over the conductive layer. A photoresist layer is then formed and patterned over the silicon nitride layer. The silicon nitride layer and the conductive layer are etched to form an opening exposing a portion of the substrate. The photoresist layer is then removed. The exposed substrate and a portion of the conductive layer exposed along the sidewalls in the opening are oxidized. An planarizing insulating layer such as spin-on-glass is formed over the silicon nitride layer and in the opening. The insulating layer is etched back to expose the silicon nitride wherein an upper surface of the insulating layer is level with an upper surface of the conductive layer. The silicon nitride layer is then removed. A planar silicide layer is then formed over the conductive layer.
