Abstract:
1. A semiconductor construction, comprising: a first region of a silicon-containing substrate having first features, and a second region of the silicon-containing substrate having second features; the first features being more closely spaced than the second features; the first region interfacing with the second region along an electrically insulative material; a first insulative material over the second region, and having a top surface below upper surfaces of the first features; a second insulative material over the first insulative material and having a different composition from the first insulative material; the second insulative material being configured as a structure having an upwardly-extending stem joined to a horizontally-extending bench; the bench having an upper surface at about a common level as upper surfaces of the first features; the stem extending to above the upper surfaces of the first features; and a conductive material within the second region and extending through the first and second insulative materials.
