Leadframe plasma cleaning
WebPlasma was generated by a d.c. bias of 200 V on to the substrate holder and leadframes using Ar or Ar/H2 (1:4) as the working gases. Cleaning times were 2-5 min and 12 min … WebIn case of plasma treatment, charging damage caused by ion bombardment can be a serious challenge. It leads to degradation of electrical characteristics of devices. UV-ozone treatment offers surface treatment using oxygen radicals without plasma discharge. No hazardous effluent. Wet cleaning requires effluent disposal of chemicals.

WebThe plasma etching (PE) is an absolute chemical etch process (chemical dry etching, CDE). The advantage is that the wafer surface is not damaged by accelerated ions. Due to the movable particles of the etch gases the etch profile is isotropic, thus this method is used to remove entire film layers (e.g. back side clean after thermal oxidation).
