Claim:
1. A method of forming a layer, the method comprising: providing a first insulator and a second insulator over a lower structure, the first and second insulators vertically spaced apart from the lower structure, and the first and second insulators laterally spaced apart from each other, wherein an uppermost portion of the lower structure is a conductive layer having a crystal structure; generating a first ion source and a second ion source from the first insulator and the second insulator, respectively; forming an insulating layer on the lower structure using the first ion source and the second ion source, wherein at least a portion of the insulating layer is in an amorphous state; and performing a thermal treatment process on the insulating layer, wherein the thermal treatment process crystallizes the portion of the insulating layer in the amorphous state to match a lattice of the crystal structure of the conductive layer, and wherein the first insulator and the second insulator comprise the same material as each other.
