Abstract
The present invention may provide an integrated device, which may include a substrate having first and second regions, the first region spaced apart from the second region, a first heterojunction bipolar transistor (HBT) device formed on the first region of the substrate, the first HBT device having a first collector layer formed above the first region of the substrate, the first collector layer having a first collector thickness and a first collector doping level, and a second HBT device formed on the second region of the substrate, the second HBT device having a second collector layer formed above the second region of the substrate, the second collector layer having a second collector thickness and a second collector doping level, the second collector thickness substantially greater than the first collector thickness, the second collector doping level lower than the first collector doping level.
