Title: Frank Marazita: Innovator in Semiconductor Technology
Introduction
Frank Marazita is a notable inventor based in San Jose, California. He has made significant contributions to the field of semiconductor technology, holding a total of 7 patents. His work primarily focuses on enhancing the performance and reliability of electronic devices.
Latest Patents
One of his latest patents is for a transistor device with increased breakdown voltage. This bipolar lateral device is designed to have a high BV.sub.ceo, formed through a single polysilicon process. In one embodiment, silicide is excluded from the surface of the N+ doped polysilicon, protecting the N- base width region, resulting in a BV.sub.ceo of 8 to 10 V. In another embodiment, the polysilicon is maintained as intrinsic, achieving a BV.sub.ceo of about 20 V. These devices are particularly useful as voltage clamping devices in programmable logic circuits that require the ability to withstand significant reverse bias voltages.
Another significant patent involves a vertical fuse device. This structure includes a lightly-doped shallow emitter that enhances fusing characteristics. The design features a buried collector, an overlying base, and an emitter positioned above the base. The emitter extends approximately 0.2 microns from the upper surface, with a specific dopant concentration. The innovative design allows for improved programming of the fuse through the shorting of the emitter, which is facilitated by heating the metal/emitter interface.
