Claim 11:
12. A semiconductor device, comprising:
a stack of alternating dielectric materials and conductive materials, the dielectric materials of the stack comprising at least two different portions abutting one another along horizontal interfaces therebetween;
charge storage structures laterally adjacent to the conductive materials of the stack, the charge storage structures comprising a uniform height across a length thereof and the height of the charge storage structures the same as the height of the laterally adjacent conductive materials of the stack;
a charge block material between the charge storage structures and the respective laterally adjacent conductive materials of the stack, a portion of the charge block material extending within recessed regions of the dielectric materials of the stack; and
a channel material vertically extending through the stack of alternating dielectric materials and conductive materials, sidewalls of the channel material exhibiting a slope.
