A three-dimensional memory device includes an alternating stack of word lines and at least one insulating layers or air gaps located over a substrate, a memory opening fill structure extending through the alternating stack. The memory opening fill structure includes a memory film and a vertical semiconductor channel contacting an inner sidewall of the memory film. The word lines are thicker than the insulating layers or air gaps.
