Patent ID: 11927890
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 9:
10. A substrate processing apparatus comprising:
a photoresist coater configured to apply a metal photoresist film on a substrate;
an exposer configured to irradiate the metal photoresist film with light;
a photoresist develop unit configured to develop the irradiated metal photoresist film on the substrate;
a baking unit configured to bake the substrate with the developed photoresist film;
a dehumidifier configured to reduce an amount of moisture in an ambient to which the substrate is exposed,
wherein the dehumidifier is spatially separated from the photoresist coater, the exposer, the photoresist develop unit, and the baking unit,
wherein the photoresist coater and the photoresist develop unit are disposed in a first area,
wherein the baking unit is disposed in a second area facing the first area, and
wherein the dehumidifier is disposed in a space between the first area and the second area; and
a transfer unit disposed in the space between the first area and the second area and configured to transfer a substrate received from one of the photoresist coater and the photoresist develop unit using a transfer robot,
wherein the transfer robot passes through the dehumidifier.
