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.

From i.r. interference chart analysis of an epitaxial wafer made of silicon nn+ layers, it wasfound that: (a) the interference amplitude varies sensitively with impurity concentration of the substrate wafers; (b) the interference amplitude damps and

The emitter-current dependence of α cb of the p-n-p alloy transistor is affected by various factors. One of the important factors at low emitter-current densities is the ratio between donor concentration in base region and acceptor concentration in
