Title: Method of forming shallow junction layer
Inventor: HASEGAWA MASAHIRO
IPC: H01L29/78
Filed: 1988-12-20
Abstract: PURPOSE:To form a source-drain regions where the junction depth is shallow, the junction leak currents are small, and the layer resistance is low by performing mixing and heat treatments after exposing a silicon substrate to the plasma of group III elements such as boron, etc., or group V elements such as phosphorus, etc., so as to for a shallow predeposition layer. CONSTITUTION:By exposing a substrate 1, whereon a gate oxide film 3, a polysilicon gate electrode 4, and a spacer 5 are formed, to plasma of diborane gas of argon base, boron is allowed to permeated source and drain regions so as to form a predeposition layer 6 shallowly. At this time, metallic layers 7 of boron are accumulated at the surface of the source and drain regions. Next, silicon ions are implanted so as to do mixing between the metallic layer 7 of boron and the silicon substrate 1. Subsequently, as an interlayer insulating film, an NSG film 9 and a BPSG (boron-phosphorous silicate glass) film 10 are accumulated and are subjected to heat treatment, whereby reflow of the BPSG film is performed and at the same time it is recovered from the damage which is generated by implantation of silicon ions. Hereby, the source and drain regions 8 which are shallow and in high concentration can be formed.
