    摘要: Methods for processing substrates in twin chamber processing systems having first and second process chambers and shared processing resources are provided herein. In some embodiments, a method may include flowing a process gas from a shared gas panel to a processing volume of the first process chamber and to a processing volume of the second process chamber; forming a first plasma in the first processing volume to process the first substrate and a second plasma to process the second substrate; monitoring the first processing volume and the second processing volume to determine if a process endpoint is reached in either volume; and either terminating the first and second plasma simultaneously when a first endpoint is reached; or terminating the first plasma when a first endpoint is reached in the first processing volume while continuing to provide the second plasma in the second processing volume until a second endpoint is reached.

    摘要: Methods for processing substrates in dual chamber processing systems comprising first and second process chambers that share resources may include performing a first internal chamber clean in each of the first process chamber and the second process chamber; and subsequently processing a substrate in one of the first process chamber or the second process chamber by: providing a substrate to one of the first process chamber or the second process chamber; providing a process gas to the first process chamber and the second process chamber; forming a plasma in only the one of the first process chamber or the second process chamber having the substrate contained therein; and providing an inert gas to the first process chamber and the second process chamber via one or more channels formed in a surface of respective substrate supports disposed in the first process chamber and the second process chamber while processing the substrate.

    摘要: A method of making a semiconductor structure includes etching an anti-reflective coating layer at a pressure of 10 millitorr or less; etching a nitride layer with a first nitride etch plasma having a first F:C ratio; and etching the nitride layer with a second nitride etch plasma having a second F:C ratio. The first F:C ratio is greater than the second F:C ratio.
