Abstract
For the first time a SiGe:C Heterojunction Bipolar Transistor (HBT) is presented that uses the Resurf effect to improve the cutoff frequency (f T) for a specified collector-base junction breakdown voltage (BV CB0). By using trenches filled with intrinsic silicon adjacent to the collector drift region the electric field profile can be reshaped so that a high breakdown voltage (> 20V) can be combined with a high drift doping concentration. This allows for high current densities and consequently a high fT. Experimental results show an increase of the f T×BVCB0 product of up to a factor of two by using Resurf, the maximum value obtained is 670 GHzV.
