Latest Patents

Hollins' latest patents include the Simplified BIFET process and the Simplified BIFET structure. In these innovations, conventional bipolar transistors are fabricated alongside thin ion implanted junction field effect transistors to create BIFET structures. The process begins with conventional isolation diffusion, followed by stripping off the surface oxide. The semiconductor wafer is then ion implanted with slow diffusing impurities of a conductivity type that matches the undiffused surface material. Subsequently, bipolar transistors and junction field effect transistors are fabricated using conventional oxide masked diffusion processes. The sources and drains of the field effect devices utilize the base diffusions of the bipolar transistors, while the gate contact is achieved through an emitter diffusion. The channels of the field effect devices are formed at a depth significantly greater than that of the impurities deposited during the original ion implant. If desired, an ion implanted top gate can be established over the channel. The wafer is then annealed and processed according to conventional techniques. The original ion implant covers the entire surface of the circuit, acting as a field inversion prevention layer, which enhances circuit reliability. Notably, the field effect devices can be fabricated with one less masking step compared to prior processes.
