| Outline of Final Research Achievements |
Purpose of this study was to establish the technology for forming the high-mobility CMOS using a common III-V semiconductor material for the n-channel and p-channel. GaSb and InGaAs were chosen as the candidate materials. For GaSb, high-quality MOS interfaces were achieved while the relation between the interface dipoles and interface traps were examined. Surface treatment processes for GaSb were also established. Furthermore, nanocontact heteroepitaxy technique was developed for growing high-quality GaSb layer on Si. For InGaAs, In/Ga cation ordering was investigated as a possible method of the band engineering. The first-principles calculations showed that the effective mass of the carriers were affected by the ordering. Current drivability and delay time in the III-V MOSFETs were analyzed by using Monte Carlo simulation considering the quantum effects.
