Imec today announced a cryogenic etching method that protects the surface of porous ultralow-k dielectrics against excessive plasma induced damages.
As semiconductor technology scales below the 20nm node, the capacitance increases between nearby conductive portions of high-density integrated circuits, resulting in loss of speed and cross-talk of the device. To control the increase in capacitance in deeply-scaled devices, insulating layers of porous low-k dielectrics are integrated through plasma etching. However, plasma etching exposes the dielectrics to active plasma radicals that penetrate deeply into the porous substrate, which then react and change the composition of the dielectric.
