Latest Patents

Ichinose's latest patents include a semiconductor device designed to streamline the manufacturing process. This innovative device features a protective chip equipped with a surface Zener diode, which safeguards a light-emitting chip containing an LED from surge voltage. The protective chip is strategically mounted over wiring that is electrically connected through a metal wire to an anode electrode. This electrode is linked to a p-type semiconductor region, which shares the same conductivity type as the semiconductor substrate of the chip. Notably, the anode electrode of the protective chip is electrically connected to the back surface of the chip without a PN junction. This design ensures that even if the back surface contacts the wiring, the electrical characteristics of the Zener diode remain unaffected. Consequently, there is no need to create an insulating film on the back surface of the chip to prevent contact with the wiring, thereby simplifying the overall manufacturing process.
