Good point

・Suitable for multi step process due to PLL high speed matching technology that we have originally developed.
・Realization of high process rate with high density radicals.
・Realization of low damage process using floating potential ICP.
・All-in-one compact design: An RF power supply and a plasma generator are integrated into a single structure.


・Organic layer ashing by oxygen radical
・Organic layer ashing by hydrogen radical
・CVD chamber cleaning
・Surface preparation (Nitrization or oxidization of Si (and SiO2))
・Radical process
・Si etching
