Abstract:
Methods of forming semiconductor device structures include forming trenches in an array region and in a buried digit line end region, forming a metal material in the trenches, filling the trenches with a mask material, removing mask the mask material in the trenches to expose a portion of the metal material, and removing the exposed portion of the metal material. A plurality of conductive contacts is formed in direct contact with the metal material in the buried digit line end region. Methods of forming a buried digit line contact include forming conductive contacts physically contacting metal material in trenches in a buried digit line end region. Vertical memory devices and apparatuses include metallic connections disposed between a buried digit line and a conductive contact in a buried digit line end region.

Claim (Index 7):
The apparatus of  claim 6 , wherein the lower portion of each of the semiconductor pillars is elongated in the first direction to be continuous with the lower portion of an adjacent one of the semiconductor pillars.
