Patent ID: 7572333

Claim:
A method for manufacturing a semiconductor comprising: preparing a hot plate which heats a sapphire substrate, a support table having a support plate and support portions and disposed as being spaced away from the hot plate by a first interval, and an elevating device which moves the support table up and down; disposing the sapphire substrate by the support portions as being respectively spaced between the hot plate and the support table, in such a manner that back surfaces of the hot plate and the sapphire substrate are opposite to each other, the sapphire substrate being spaced away from the hot plate by a second interval and being spaced away from the support table by a third interval; externally blocking off spacing defined between the hot plate and the sapphire substrate, and spacing defined between the sapphire substrate and the support table; after blocking off thereof from outside, heating up the hot plate to thereby heat up the sapphire substrate; and elevating the support table by the elevating device to bring the back surface of the heated-up sapphire substrate into contact with the hot plate.
