Abstract:
The invention includes semiconductor constructions having trenched isolation regions. The trenches of the trenched isolation regions can include narrow bottom portions and upper wide portions over the bottom portions. Electrically insulative material can fill the upper wide portions while leaving voids within the narrow bottom portions. The trenched isolation regions can be incorporated into a memory array, and/or can be incorporated into an electronic system. The invention also includes methods of forming semiconductor constructions.

Claim (Index 60):
A memory array, comprising:\n a semiconductor substrate; a trench extending into the substrate and proximate a transistor, the trench comprising an upper portion over a lower portion; a liner along an interior wall of the lower and upper portions of the trench, the liner comprising a step at the transition between the lower portion and the upper portion, the liner being the only liner in the trench; a first electrically insulative material in the lower portion of the trench, the first electrically insulative material comprising a first composition that includes a void; and a second electrically insulative material in the upper portion of the trench, the second electrically insulative material comprising a second composition different from the first composition of the first electrically insulative material.
