A new emitter layout in SiGe HBT is presented to improve the thermal stability. For comparison, a SiGe HBT with conventional layout is also fabricated. The thermal resistance and I-V characteristics of two types of HBTs at different biases and ambient temperature are measured and compared. Experimental results show that the new emitter layout is very… CONTINUE READING
