Abstract:
The present invention relates to an apparatus for removing fume which includes, a wafer cassette for stacking wafers; and an exhaust for exhausting the fume of the wafers stacked in the wafer cassette, wherein the wafer cassette includes stacking shelves provided at both sides for stacking wafers; and a front opening for incoming and outgoing of the wafers which are being stacked in the stacking shelf, wherein the stacking shelves include multiple inclined ramp portions which are slanted towards the wafers stacked in the stacking shelves as they travel towards the front opening, wherein a purge gas outlet is provided in the inclined ramp portion for supplying purge gas for the wafers stacked in the stacking shelves. According to the present invention, the residual process gases on wafers can be removed efficiently.

Claim (Index 1):
An apparatus for removing fume, comprising:\n a wafer cassette provided with stacking shelves for stacking wafers; a purge gas outlet for supplying purge gas to said wafers stacked in said wafer cassette; an exhaust for exhausting the purge gas and the fume of said wafers supplied from said purge gas outlet; a compressed air discharge accelerator provided in said exhaust; a regulator for uniformly maintaining a flow rate of a fluid supplied to said compressed air discharge accelerator; and an exhausting gas pressure sensor for detecting exhausting air pressures of said purge gas and said fume, wherein the exhausting flow rates of said purge gas and said fume are increased by increasing the flow rate of said fluid passing through said regulator, or the exhausting flow rates of said purge gas and said fume are decreased by decreasing the flow rate of said fluid passing through the regulator.
