The patented FlexTRAK™-WF plasma chamber design provides exceptional etch uniformity and process repeatability. Primary plasma applications include a variety of etching, ashing, and descum steps. Other plasma processes include contamination removal, surface roughening, increasing wettability, and enhancing bonding and adhesion strength.
Applications include wafer processing prior to typical back-end packaging steps - suitable for wafer-level packaging, flip chip, or traditional packaging.
