Abstract

A substrate liquid processing apparatus including: a substrate rotary-holding unit configured to rotate a substrate while holding the substrate; and a processing liquid supply unit configured to supply a processing liquid to a bottom surface of the substrate held by the substrate rotary-holding unit. The substrate rotary-holding unit includes: a base plate disposed spaced apart from the substrate below the substrate; a cover member supported by the base plate and disposed outside an outer periphery of the substrate; and a discharge port formed between the base plate and the cover member and configured to discharge an air stream occurring below the substrate. The support portion of the base plate and the cover member protrudes outwards from a top surface of the base plate to be connected to the cover member.
