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 43):
A method of forming a semiconductor construction, comprising:\n providing a semiconductor substrate; forming a trench in the substrate, the trench having a lower region and an upper region over the lower region; forming a liner within the trench to narrow the trench; providing non-oxidized silicon to be along the liner within the lower region of the trench and not along the liner within the upper region of the trench; while the non-oxidized silicon is along the liner within the lower region of the trench, reducing the thickness of the liner along the upper region of the trench; converting the non-oxidized silicon to silicon dioxide; and after reducing the thickness of the liner along the upper region of the trench, forming electrically insulative material over the silicon dioxide to fill the upper region of the trench.
