✦ Synopsis


We derive for the fast time a mechanism of reactive plasma etch-mg in the system Si/F by the quantum-chemical approach. Sii-'+ic species at the surface play an important role. Sil'3 surface compleses also occur. The final etching braduct Siiy4 is formed with high probability in the gas phase.

## Abstract The electronic and geometric structures of the CH~3~Li/acrylonitrile (AN) and CH~3~Li/2AN systems were investigated by the semiempirical quantum‐chemical MNDO1MNDO: Modified neglect of differential overlap. method. For the CH~3~Li/AN system a fundamental difference was found between th
