Abstract

A method of forming a microelectronic device comprises treating a base structure with a first precursor to adsorb the first precursor to a surface of the base structure and form a first material. The first precursor comprises a hydrazine-based compound including Si—N—Si bonds. The first material is treated with a second precursor to covert the first material into a second material. The second precursor comprises a Si-centered radical. The second material is treaded with a third precursor to covert the second material into a third material comprising Si and N. The third precursor comprises an N-centered radical. An ALD system and a method of forming a seal material through ALD are also described.
