Boron and phosphorous diffusion in ion-beam-sputtering deposited SiGe films
Materials Letters 57(2002)921-924，-0001，（）：
Conventional dopant diffusion technique has been successfully employed to dope SiGe films deposited by ion-beam sputtering (IBS). The deposited a-SiGe films can be doped to both p and n types after boron and phosphorous diffusions at a temperature range of 850-1000℃. The doping process is accompanied by crystallization of the a-SiGe film. Electrical properties of the doped SiGe films have been characterized by a four-point probe and Hall measurements. Hall mobilities as high as 13 and 31cm2/V·s have been obtained in boron-and phosphorous-doped polycrystalline SiGe films, respectively.
