Abstract: Methods of forming integrated circuit devices include forming an etch stop layer on a surface of a semiconductor substrate and forming a first interlayer insulating layer on the etch stop layer. The first interlayer insulating layer is patterned to define an opening therein that exposes a first portion of the etch stop layer. This first portion of the etch stop layer is then removed to thereby expose an underlying portion of the surface of the semiconductor substrate. This removal of the etch stop layer may be performed by wet etching the first portion of the etch stop layer using a phosphoric acid solution. A semiconductor region is then selectively grown into the opening, using the exposed portion of the surface of the semiconductor substrate as an epitaxial seed layer.
