Abstract:
1. A semiconductor substrate processing apparatus comprising: a frame; a semiconductor substrate support to support a semiconductor substrate, the semiconductor substrate having a central axis; a dispense head connected to the frame to dispense a semiconductor processing fluid onto the semiconductor substrate; and a catch cup section attached to the frame having an inner surface and an outer surface, at least a portion of the inner surface not facing towards the central axis of the semiconductor substrate, wherein the catch cup further comprises a lip extending from the inner surface thereof towards the central axis of the semiconductor substrate, and wherein the lip is angled such that an inner portion of an upper surface of the lip is higher than an outer portion of the upper surface of the lip, and wherein the lip comprises a top lip having an inner tip curving downward toward a plane of the semiconductor substrate support.
