摘要： A semiconductor structure. A hard mask layer is on a top substrate surface of a semiconductor substrate. The hard mask layer includes a hard mask layer opening through which a portion of the top substrate surface is exposed to a surrounding ambient. The hard mask layer includes a pad oxide layer on the top substrate surface, a nitride layer on the pad oxide layer, a BSG (borosilicate glass) layer on top of the nitride layer, and an ARC (anti-reflective coating) layer on top of the BSG layer. A BSG side wall surface of the BSG layer is exposed to the surrounding ambient through the hard mask layer opening.
