Claim 3:
4. The method of claim 2, wherein:
forming a first dielectric spacer structure within the trench comprises:
forming a first portion of the first dielectric spacer structure to physically contact a first of the additional insulative structures; and
forming a second portion of the first dielectric spacer structure to physically contact a second of the additional insulative structures vertically neighboring the first of the additional insulative structures; and

forming a second dielectric spacer structure within the trench comprises:
forming a first portion of the second dielectric spacer structure to physically contact a third of the additional insulative structures vertically underlying the second of the additional insulative structures; and
forming a second portion of the second dielectric spacer structure to physically contact a fourth of the additional insulative structures vertically neighboring the third of the additional insulative structures.
