    Abstract: A batch-type etching device and a method, which enable a stable process with high reproducibility by preventing contamination of CVD equipment by effectively removing H 2 O, CH 3 OH or CH 3 COOH and byproducts adsorbing and remaining on the surface of a semiconductor wafer after etching is completed, are provided. The device comprises a reaction chamber (1), an exhaust port (5) for evacuating the air inside the reaction chamber, a wafer-supporting boat (2) for supporting at least one batch of semiconductor wafers (4) inside the reaction chamber, a gas inlet port (3) for introducing a reaction gas into the reaction chamber, and a microwave generator (11). The microwave generator is adapted to introduce microwaves into reaction chamber so that substances which adsorb and remain on the semiconductor wafers are desorbed and removed after etching is completed.
