Abstract
In0.86Al0.14As/In0.86Ga0.14 As double heterojunction bipolar transistors (DHBTs) were grown on InP substrates by using sub-micron 6.0 Aring metamorphic graded buffer layers. Good DC and RF characteristics have been demonstrated with a current gain of 30, low base-collector reverse leakage (<muA), low turn-on voltage (0.45 eV), practical breakdown voltage (~2.5 V), and peak frequencies fT and fMAX exceeding 150 GHz. Functional circuits with complexity ranging from 20 to 1100 devices have been successfully demonstrated with power dissipation reduced by a factor of two compared to equivalent circuits designed with conventional InP technology
