Two different types of paramagnetic centers in silicon, Si-P3 (neutral {110} planar tetravacancies) in a well defined crystalline structure and point defects with poorly defined local structure in substantially damaged crystalline environments, forme

The radiation damage in SiO2 films thermally grown on silicon and bombarded by ion and neutral beams has been studied by electron spin resonance (ESR). It is found that the E' center generation yield is much higher for ion bombardment than for neutra

Silicon dioxide films thermally grown on Si are irradiated with vacuum ultravioulet (VUV) photons (16.7 and 16.8 eV) as the films are supplied with bias voltages between -10 and 10 V. The resultant positive charges and E' centers in the films are stu

The Si etch rate in an (F2+O2) microwave plasma has been measured as a function of O2 mixing ratio at a fixed total pressure of 5.3×10−2 Pa. The etch rate significantly decreases with the mixing ratio. This etch rate decrease is due primarily to s

A hot Cl2 molecular (Cl*2) beam was successfully applied to achieve highly anisotropic, highly selective, and almost damage‐free etching of polycrystalline Si. The anisotropy, the ratio of etch rates in vertical and horizontal directions, was large

Heavily arsenic implanted silicon layers are evaluated by measuring the “refreshtime” of dynamic type MOS memories. The dose range used for the fabrication is around 1.5×10 16 cm −2 due to the sheet resistivity and junction depth requirements.
