IPC: H01L21/31
Filed: 1988-12-14
Abstract: PURPOSE:To effectively prevent film from depositing on parts except a substrate by moving a substrate cooled in a cooling chamber into a deposition chamber, and performing film depositing. CONSTITUTION:In a cooling chamber, a semiconductor wafer 3 is cooled at a temperature equal to or lower than the dew point of deposition seed; then the semiconductor wafer 3 is carried into a deposition chamber 4 via a gate valve 5 by a conveying apparatus not shown in figures; the wafer is made to be retained by a wafer retainer 6; active deposition seed are supplied into a deposition chamber 4 through a pipe 9 by an active seed generating apparatus 8. In the deposition chamber 4, the semiconductor wafer 3 surface only is cooled at a temperature equal to or lower than the dew point of the deposition seed, so that condensation generates almost only on the semiconductor wafer surface, and does not generate on any other part. As a result, the possibility that the film is deposited on a part except the wafer 3 is not present, and further the frequency of maintainance to eliminate the generated film can be reduced.

For the etching, hydrofluoric acid is pref. used. For further improving the durability of the above member, it is recommended that the face of the thermally cracked carbon layer 22 be coated with an oily lubricant such as silicone grease.
