A method of forming a FinFET with a rounded source/drain profile comprises forming a fin in a substrate, etching a source/drain recess in the fin, forming a plurality of source/drain layers in the source/drain recess; and etching at least one of the plurality of source/drain layers. The source/drain layers may be a silicon germanium compound. Etching at the source/drain layers may comprises partially etching each of the plurality of source/drain layers prior to forming subsequent layers of the plurality of source/drain layers. The source/drain layers may be formed with a thickness at a top corner of about 15 nm, and the source/drain layers may each be etched back by about 3 nm prior to forming subsequent layers of the plurality of source/drain layers. Forming the plurality of source/drain layers optionally comprises forming at least five source/drain layers.
