摘要
An apparatus comprising a semiconductor substrate; a conductively doped source or drain (source/drain) region at the surface of the substrate; a raised semiconductor layer deposited over the source/drain region to form a raised source/drain region; a via formed in the raised source/drain region having substantially vertical sidewalls reaching partly or substantially to the source/drain region; and a metal contact filling the via.
