Abstract
A semiconductor structure includes an alternating stack of insulating layers and electrically conductive layers, a memory opening vertically extending through the alternating stack and a memory opening fill structure located in the memory opening. A Group IV-containing material portion is formed by selective deposition on an end portion of the vertical semiconductor channel. Alternatively, a backside semiconductor cap structure can be formed directly on a bottom surface of the vertical semiconductor channel by selective or non-selective deposition of a semiconductor material.
