Abstract:
.mu.m and a length dimension of approximately 1.3 .mu.m so as to define a second area;said floating gate having a width dimension of approximately 0.35 .mu.m and a length dimension so as to define a third area;said width dimension of said tunnel window being less than said width dimension of said programmable junction region so that said width dimension of said programmable junction region overlaps said width dimension of said tunnel window;said length dimension of said tunnel window being less than said length dimension of said programmable junction region so as to be confined within the length dimension of said programmable junction region;said width dimension of said floating gate being less than said length dimension of said tunnel window so that said length dimension of said tunnel window is overlapping opposed edges of said floating gate by approximately 0.5 .mu.m;said length dimension of said floating gate being larger than said width dimension of said tunnel window so that said length dimension of said floating gate is overlapping said width dimension of said tunnel window; andsaid second area of said tunnel window being completely confined within the first area of said programmable junction region so as to form a field-edgeless tunneling window region having a width dimension of about 0.5 .mu.m and a length dimension of about 0.35 .mu.m underneath the third area of said floating gate.
