Substrate processing apparatus
First Claim
1. A substrate processing apparatus comprising:
- a transfer chamber where a substrate is transferred into a substrate retainer;
an upper gas supply mechanism configured to supply a gas into an upper region of the transfer chamber through a first gas supply port; and
a lower gas supply mechanism disposed under the upper gas supply mechanism and configured to supply the gas into a lower region of the transfer chamber through a second gas supply port,wherein the upper gas supply mechanism comprises;
a first buffer chamber disposed at a back surface of the first gas supply port;
a pair of upper ducts disposed at both sides of the first buffer chamber; and
a first ventilation unit disposed at lower ends of the pair of upper ducts, andthe lower gas supply mechanism comprises;
a second buffer chamber disposed at a back surface of the second gas supply port;
a lower duct disposed at lower surface of the second buffer chamber; and
a second ventilation unit disposed at a lower end of the lower duct.

Abstract
A substrate processing apparatus includes a transfer chamber; an upper gas supply mechanism for supplying a gas into an upper region of the transfer chamber through a first gas supply port; and a lower gas supply mechanism configured to supply the gas into a lower region of the transfer chamber through a second gas supply port. The upper gas supply mechanism includes a first buffer chamber at a back surface of the first gas supply port; a pair of upper ducts at both sides of the first buffer chamber; and a first ventilation unit at lower ends of the pair of upper ducts. The lower gas supply mechanism includes a second buffer chamber at a back surface of the second gas supply port; a lower duct at lower surface of the second buffer chamber; and a second ventilation unit at a lower end of the lower duct.
