Patent ID: 7591601

Claim:
A coater/developer forming a coating film on a substrate in a first unit block provided at a stage subsequent to a carrier block into which the substrate has been carried with a carrier; thereafter conveying the substrate to an exposure unit through an interface block provided at a stage subsequent to the first unit block; and performing development in a second unit block on the substrate subjected to exposure in the exposure unit and returned therefrom through the interface block, and transferring the substrate to the carrier block, the second unit block being stacked on the first unit block and having a conveyance path of the substrate from the interface block to the carrier block, wherein: the second unit block includes a development module configured to perform the development on the substrate, a heating module configured to heat the substrate before and after the development, a cooling module configured to cool the substrate after the heating, and a substrate conveyance part configured to transfer the substrate to and receive the substrate from the modules, and the heating module includes a pair of rotary bodies configured to rotate about respective horizontal axles, the rotary bodies being spaced apart from each other in a direction along the conveyance path of the substrate so that the rotational axles thereof are parallel to each other; a conveyance path member engaged with and extended between the rotary bodies so as to move along an orbit, the conveyance path member forming a part of the conveyance path of the substrate placed on the conveyance path member; a first transfer part provided at an upstream end of the conveyance path and configured to transfer the substrate between the substrate conveyance part and the conveyance path member; a second transfer part provided at a downstream end of the conveyance path and configured to transfer the substrate between the substrate conveyance part and the conveyance path member; and a heating part provided between the upstream end and the downstream end of the conveyance path and configured to heat the substrate.
