Abstract:
A film formation apparatus for a semiconductor process and a method of using the same are provided to prevent a production yield from being lowered and the deterioration of components inside the apparatus. A method of using a film formation apparatus for a semiconductor process includes the steps of: forming a first environment where the average molecular weight of halogen acid gas is 20~23 in an upper gas path between a gas supply source of the halogen acid gas and a flow controller; supplying the halogen acid gas through the upper gas path and the flow controller in the first environment from the gas supply source, and supplying cleaning gas including the halogen acid gas to a reaction chamber of the formation apparatus; and etching and removing a byproduct film attached to the inner surface of the reaction chamber by the cleaning gas.

PURPOSE: A method and a system for removing metal contaminant attached to a quartz member of a vertical annealing apparatus are provided to remove the metal contaminant attached to the quartz member by dipping the quartz member into a cleaning bath accommodating a cleaning solution. CONSTITUTION: A quartz member not installed in a vertical annealing apparatus is comprised. A diluted hydrofluoric acid cleaning is performed by cleaning the quartz member using a diluted hydrofluoric acid. A first deionized water cleaning is performed by cleaning the quartz member using deionized water. A hydrochloric acid cleaning is performed by cleaning the quartz member with hydrochloric acid. A second deionized water cleaning is performed by cleaning the quartz member with deionized water. An exhaust pipe(44) is arranged on the bottom of a cleaning bath(41) of a deionized water cleaning apparatus(4). A pump(45), a filter(46) and a valve(47) are installed in the exhaust pipe.
Abstract:
A gas supply apparatus, a gas supply method, a cleaning method of a thin-film forming apparatus, a thin-film forming method and a thin-film forming apparatus are provided to clean a heat treatment apparatus stably by preventing damage of components near a nozzle of a hydrogen inlet. A thin-film forming apparatus(1) comprises a reaction chamber(2) and an exhaust tube(5). A fluorine inlet and a hydrogen inlet are connected with the reaction chamber, so as to supply a cleaning gas containing the fluorine and hydrogen into the reaction chamber or exhaust tube. The hydrogen inlet comprises an internal flow channel and an external flow channel which covers the internal flow channel. The hydrogen is supplied through the internal flow channel, and the nitrogen is supplied from the external flow channel. Thus, the hydrogen supplied from the internal flow channel is supplied from the hydrogen inlet, in a state that the hydrogen is surrounded with the nitrogen.
