A version of Kontsevich formality theorem is proven for smooth DG algebras. As an application of this, it is proven that any quasiclassical datum of noncommutative unfolding of an isolated surface singularity can be quantized.

Keywords: Kontsevich formality theorem, dg algebras, operads, hypersurface singularity
