摘要

Graded Ge fraction SiGe film was grown by using newly-designed SGE500 SiGe UHV/CVD system. The film quality was determined by X-ray diffraction. SiGe hetero-junction bipolar transistor (HBT) device with this SiGe film was made. Results showed that the quality of the graded SiGe film was high and the SiGe HBT device had good electrical performance.
