SUBSTRATE SUPPORTING UNIT, SUBSTRATE PROCESSING APPARATUS, AND METHOD OF MANUFACTURING SUBSTRATE SUPPORTING UNIT

摘要

Disclosed are a substrate supporting unit, a substrate processing apparatus, and a method of manufacturing the substrate supporting unit. The substrate supporting unit includes a susceptor (12) provided with heaters (15a, 16b) to heat a substrate placed on the susceptor (12), and including a first temperature region and a second temperature region having a higher temperature than that of the first temperature region; and a heat dissipating member (20) including a contact surface (21) being in thermal contact with the second temperature region. The heat dissipating member (20) further includes an opening (23) corresponding to the first temperature region. The heat dissipating member (20) formed in a ring shape, in which the opening (23) is surrounded with the contact surface (21), and the contact surface (21) of the heat dissipating member (20) makes thermal contact with the lower surface of the susceptor (12).
