Abstract:
1. A circuit comprising one or more semiconductor devices, at least one of the one or more semiconductor device comprising: a polysilicon shape having a bridging vertex, the bridging vertex formed over a silicon area; a spacer on a vertical side of the polysilicon shape except on the bridging vertex; and, a silicide formed on the polysilicon shape and on the silicon area thereby creating an electrical coupling between the polysilicon shape and the silicon area at the bridging vertex; wherein a bridging vertex is a portion of a particular polysilicon share on a semiconductor chip, the portion having an angle, equal to or less than a critical angle, as seen from a top view, acute enough to prevent a sidewall spacer being formed on a vertical surface of the particular polysilicon shape at the bridging vertex during a step of processing the semiconductor chip having the plurality of polysilicon shapes, including the particular polysilicon shape, and the silicon area, thereby allowing silicide to form on the vertical surface of the particular polysilicon shape at the bridging vertex in a silicide step performed during processing of the semiconductor chip.
