Patent ID: 7488688

Claim:
A method of removing an oxide layer using a semiconductor manufacturing apparatus, comprising: (a) placing a vertically movable susceptor at a lower portion of a processing chamber and loading a wafer onto the vertically movable susceptor; (b) supplying a cooling water or cooling gas into a cooling line in the susceptor to adjust a temperature of the wafer; (c) flowing a hydrogen gas in a plasma state and a fluorine-containing gas into the processing chamber to induce a chemical reaction with the oxide layer on the wafer; (d) moving the susceptor up to an upper portion of the processing chamber; (e) annealing the wafer mounted on the susceptor with a heater installed at the upper portion of the processing chamber to vaporize a byproduct resulting from the chemical reaction; and (f) exhausting the vaporized byproduct out of the processing chamber.
