发明名称 Manufacturing method for overvoltage protection device used in communication system, involves forming emitter region on base region, and forming electrode region on emitter region
摘要 <p>The method involves etching a first masking layer to form multiple masking regions to define a first region and a second region. A voltage-limiting region (33) and a P-type base region (32) are formed in the first region and second region respectively. An emitter region (34) is formed on the base region. An electrode region (31) is formed on the emitter region. An independent claim is also included for an overvoltage protection device.</p>
