Latest Patents

One of his latest patents is for a Triac array. This invention involves thyristors of one conductivity type formed as an array in a first semiconductor body, which are connected in parallel with thyristors of the opposite conductivity type in a second semiconductor body. This configuration produces an array of triacs. In each body, the thyristors are separate except for a common anode or cathode region and terminal connection. They are formed in an epitaxial layer divided by PN junction isolation regions on a substrate of opposite conductivity type. Notably, the thyristors can be triggered by gating signals of either polarity. Another significant patent is for a Power bipolar transistor. This invention features a bipolar power transistor with a plurality of elongated emitter parts connected to a common emitter metallization. A shaped resistive region is placed between the emitter parts and the emitter metallization to compensate for differences in the resistance presented by the metallization itself.
