Description

B atomic-layer doping in Si/Si1-xGex(100) (x = 0.3, 1) heterostructure utilizing BCl3 reaction on Si1-xGex(100) and subsequent Si epitaxial growth by SiH4 reaction was investigated by ultraclean low-pressure chemical vapor deposition. On 1/3-1/2 atomic layer (2.3-3.5 x 1014 cm-2) B formed Si1-xGex(100) achieved self-limitedly with high Cl coverage, the adsorbed Cl atoms are effectively removed by SiH4 exposure at 300 deg. C after BCl3 exposure. Furthermore, it was found that the SiH4 reaction at 300 deg. C on Ge(100) is enhanced by B adsorption
