What it is
General reference — not yet source-verifiedThe YES 58 HMDS Vapor Prime is a vapor prime oven manufactured by Yield Engineering Systems (YES). Such ovens apply a vapor of hexamethyldisilazane (HMDS) to the surface of semiconductor wafers. HMDS acts as an adhesion promoter for photoresist layers applied in photolithography.
How it works
General reference — not yet source-verifiedA vapor prime oven operates under a controlled vacuum and temperature environment. Wafers are placed in a chamber that is evacuated and then backfilled with HMDS vapor. The vapor reacts with the wafer surface to form a hydrophobic monolayer that improves resist adhesion. The process typically includes a dehydration bake before the prime step and a post-prime bake to stabilize the layer.
