摘要： A substrate processing apparatus has a chamber with a substrate transport to transport a substrate onto a substrate support in the chamber, a gas supply to provide a gas in the chamber, a gas energizer to energize the gas, and a gas exhaust to exhaust the gas. A controller operates one or more of the substrate support, gas supply, gas energizer, and gas exhaust, to set etching process conditions in the chamber to etch a plurality of substrates, thereby depositing etchant residues on surfaces in the chamber. The controller also operates one or more of the substrate support, gas supply, gas energizer, and gas exhaust, to set cleaning process conditions in the chamber to clean the etchant residues. The cleaning process conditions comprise a volumetric flow ratio of O2 to CF4 of from about 1:1 to about 1:40.

摘要： Non-metallic deposits are selectively removed from aluminum containing substrates such as aluminum faceplates using a selective deposition removal (SDR) solution. The SDR solution does not substantially etch the faceplate holes, thereby preserving the hole diameter integrity and increasing the number of times the faceplate may be cleaned or refurbished while remaining within processing hole diameter tolerances. In an embodiment, the SDR solution comprises, in wt % of the solution, 15.5%+/−2% HF or buffered HF acid, 3.8%+/−0.5% NH4F pH buffer, 59.7%+/−5% ethylene glycol, and the balance H2O.

摘要： A fluorine-free integrated process for plasma etching aluminum lines in an integrated circuit structure including an overlying anti-reflection coating (ARC) and a dielectric layer underlying the aluminum, the process being preferably performed in a single plasma reactor. The ARC open uses either BCl3/Cl2 or Cl2 and possibly a hydrocarbon passivating gas, preferably C2H4. The aluminum main etch preferably includes BCl3/Cl2 etch and C2H4 diluted with He. The dilution is particularly effective for small flow rates of C2H4. An over etch into the Ti/TiN barrier layer and part way into the underlying dielectric may use a chemistry similar to the main etch. A Cl2/O2 chamber cleaning may be performed, preferably with the wafer removed from the chamber and after every wafer cycle.
摘要翻译：一种用于等离子体蚀刻铝线的无氟集成方法，其集成电路结构包括上覆抗反射涂层（ARC）和铝下方的介电层，该方法优选在单个等离子体反应器中进行。 ARC打开使用BCl 3 / Cl 2 2或Cl 2 2和可能的烃钝化气体，优选C 2 H 2 > H 4。铝主蚀刻优选包括用He稀释的BCl 3 / Cl 2 N 2蚀刻和C 2 H 2 H 4。稀释度对于C 2 H 4 H 4的小流量特别有效。对Ti / TiN阻挡层进行过度蚀刻并且部分地进入下面的电介质可以使用类似于主蚀刻的化学。优选地，可以从晶片上取出晶片并在每个晶片周期之后进行C1 / 2 / O 2/2室清洁。
