Patent ID: 8023099

Claim:
A substrate processing system used for a light exposure apparatus which performs light exposure at least twice on each of a plurality of substrates, the substrate processing system comprising: a carrier block that transfers therefrom and thereto a carrier storing the substrates; a process section that performs a coating process to form a coating film including a photosensitive material film on each of the substrates transferred from the carrier block one by one, and that performs a developing process to develop the photosensitive material film subjected to light exposure in accordance with a predetermined light exposure pattern; an interface block that transfers the substrates between the process section and the light exposure apparatus which performs light exposure on the photosensitive material film in accordance with the predetermined light exposure pattern; and a substrate transfer mechanism that transfers the substrates among the carrier block, the process section, and the interface block, wherein the process section includes a first coating process section that performs a first coating process and a first developing process section that performs a first developing process for a first light exposure, and a second coating process section that performs a second coating process and a second developing process section that performs a second developing process for a second light exposure, and wherein the interface block includes a buffer unit to buffer the substrates, and performs buffering of the substrates at the buffer unit to set the throughput thereof to be a half of the throughput of the light exposure apparatus.
