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 36):
A method of forming a semiconductor construction, comprising:\n providing a semiconductor substrate; forming a trench in the substrate; partially filling the trench with a first material to narrow the trench, the first material having a first thickness; reducing the thickness of the first material along an upper region of the trench while the thickness of the first material along a lower region of the trench remains at the first thickness; after said reducing of the thickness, the narrowed trench having a wide upper portion joining a constricted lower portion at a step; and forming electrically insulative second material within the narrowed trench, the electrically insulative second material substantially filling the wide upper portion and leaving a void within the constricted lower portion.
