14 October 2005 Low energy inductively coupled plasma etching of HgCdTe
Author Affiliations +
The high-density inductively coupled plasma etching technique was applied to HgCdTe, while using the RF-powered wafer electrode to provide low plasma energy. By using a CH4/H2/N2/Ar chemistry the HgCdTe etch profiles were studied as a function of mask selectivity, chamber pressure, gas ratio and ICP power. The etch rate was found to decrease as etch depth increasing. The LBIC and I-V measurements were employed to investigate the electrical damage of HgCdTe material caused by plasma bombardment.
