Abstract:
1. A method of fabricating a device, comprising: depositing a base layer on a first side of a collector layer; depositing an emitter layer on the base layer; depositing a silicide layer on a second side of the collector; depositing a first oxide layer on the silicide layer on the second side of the collector layer; etching a via through the first oxide layer from a top surface of the first oxide layer to the silicide layer on the second side of the collector layer; filling the via with a conductor to form an electrical pathway to the collector through the first oxide layer; bonding the second side of the collector layer to a first substrate prior to the deposition of the first oxide layer; prior to the bonding step depositing an oxide layer around at least one side of the collector layer; depositing a passivation layer on the oxide layer and base layer and emitter layer; and depositing at least one metal contact on the passivation layer and bonding the at least one metal contact to a substrate and removing at least a portion of the first substrate.
