Abstract:
1. A semiconductor construction, comprising: a semiconductive material substrate; a conductive layer over the substrate, the conductive layer having a thin segment between a pair of thicker segments, one of the thicker segments being a first thicker segment and the other being a second thicker segment; a first gate stack over the first thicker segment and a second gate stack over the second thicker segment, the first and second gate stacks being spaced from one another by a gap extending over the thin segment; the first and second gate stacks comprising one or more conductive materials over the thicker segments and comprising one or more insulative materials over the one or more conductive materials; the stacks having sidewalls extending substantially vertically along the thicker segments, one or more conductive materials and one or more insulative materials; a masking material over portions of the first and second stacks, and having an opening extending therethrough to the thin segment; the opening having a periphery that includes the stack sidewalls; the thicker segments, one or more conductive materials and one or more insulative materials of the stacks being exposed along the stack sidewalls within the opening; and at least one conductively-doped region within the substrate under the thin segment.
