Abstract:
A method of manufacturing a semiconductor device includes providing a metal precursor on a substrate, and providing a reactant and a co-reactant to form a metal nitride layer by reaction with the metal precursor, the reactant being a nitrogen source, the co-reactant being an organometallic compound represented by Chemical Formula 1:

Abstract:
The inventive concepts provide silicon precursors, methods of forming a layer using the same, and methods of fabricating a semiconductor device using the same. The silicon precursor includes a silane group including two or more silicon atoms. The silicon precursor has a high and uniform adsorption property on surfaces of layers (e.g., a silicon layer, an oxide layer, and a nitride layer) that are mainly used when semiconductor devices are fabricated.

Methods of depositing a film are provided. The methods may include providing a substrate that includes a first surface and a second surface adjacent to the first surface; forming a polymer sacrificial layer on the first surface by using a molecular layer deposition (MLD) process; forming a first film on the second surface; and removing the polymer sacrificial layer formed on the first surface. A functional group density of the first surface may be higher than a functional group density of the second surface, and the polymer sacrificial layer may include a thermally decomposable polymer.
