SEMICONDUCTOR DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240321865 titled 'SEMICONDUCTOR DEVICE

The semiconductor device described in the abstract includes pads for high voltage, low voltage, and ground inputs, as well as a protection circuit between the high and ground voltage pads.

• The protection circuit consists of two groups of transistors arranged in different directions, with guard rings surrounding them for added protection.
• An intermediate guard ring is also included, connected to the ground pad via a resistance element.

Potential Applications: - Power electronics - Integrated circuits - Electronic devices requiring voltage protection

Problems Solved: - Protection against high voltage surges - Ensuring safe operation of semiconductor devices

Benefits: - Increased reliability of electronic systems - Enhanced safety measures for voltage-sensitive components

Commercial Applications: Title: "Advanced Voltage Protection Technology for Semiconductor Devices" This technology can be utilized in various industries such as automotive, telecommunications, and consumer electronics to improve the durability and safety of electronic devices.

Questions about the technology: 1. How does the protection circuit safeguard against high voltage inputs?

  - The protection circuit utilizes multiple transistors and guard rings to divert excess voltage away from sensitive components.

2. What is the role of the resistance element in the intermediate guard ring?

  - The resistance element helps to regulate the flow of current between the protection groups and the ground pad.
