Title: **Terumitsu Maeno: A Pioneering Innovator in Semiconductor Protection Circuits**
Introduction
Terumitsu Maeno is a notable inventor based in Iwata, Japan, recognized for his contributions to the field of semiconductor protection. With a total of three patents to his name, he has developed innovative circuits that enhance the reliability and durability of electronic devices against electrostatic discharge (ESD).
Latest Patents
Among Maeno's latest patents is the "Semiconductor Input Protection Circuit." This innovative design features a lateral PNP transistor (PB) and a lateral NPN transistor (NB) that are serially connected between an input terminal and a reference potential, typically ground. The circuit includes diodes formed in both transistors, which respond to electrostatic discharges of up to ±2000 V. When a positive ESD of +2000 V is encountered, the transistor NB activates; conversely, when faced with a negative ESD of -2000 V, the transistor PB turns on. This design effectively limits the input signal levels based on the inverse breakdown voltages of the diodes, making it an essential advancement in input protection technology.
Another significant patent under his name is the "Input Protection Circuit," which incorporates a robust ESD breakdown feature, allowing signals to be input across a wide positive and negative voltage range. This circuit utilizes a well and field insulating film within the substrate, and it integrates lateral bipolar and MOS transistors to safeguard against potential damage caused by voltage fluctuations.
