Patent JP-H02218126-A (JP)
Title: Etching apparatus
Inventor: NAKAISHI MASAFUMI
IPC: B01D53/46
Filed: 1989-02-17
Abstract: PURPOSE:To obtain an X-ray mask with less defects by keeping the inner wall of a reaction chamber at the boiling point of a reaction product, providing a trap for the reaction product in the vicinity of an exhaust system in the reaction chamber, thereby suppressing the attachment of the reaction product to material to be etched. CONSTITUTION:A reactant gas is introduced into a reaction chamber 4 through a gas introducing port 4A. The gas is exhaust through an exhaust port 4B of an exhaust system. The reactant gas inside the reaction chamber 4 is kept at a specified pressure. The inner wall of the reaction chamber 4 is heated with a heater which is used as a heating device. The chamber is kept at a temperature higher than the boiling point of the reaction product. A trap 5 for the reaction product is provided on the downstream of the exhaust gas stream in the reaction chamber 4. The trap is kept at a temperature lower than the boiling point of the reaction product. Therefore, the reaction product is in the vapor phase state in the vicinity of an X-ray absorbing film. The gas is brought into the remote part from the reacting part with the gas stream which is generated with the exhaust system. The reaction product is deposited on the trap in the solid state. Thus, the attachment of the reaction product which is generated in etching to the material to be etched is suppressed, and an X-ray mask characterized by less defects can be obtained.
