The threat of electrostatic discharge to the chip becomes more apparent
With the rapid development of information technology, the integration of chips of electronic components is getting higher and higher. iNTEL's Pentium 4 central processor chip has more than 4,000 transistors, using 0.18 micron circuit, the operation speed is doubled, and the problem caused by static electricity is increasingly prominent. As advanced semiconductor processes enter deep submicron, nano-junctions, the threat of electrostatic discharge to the chip becomes more apparent. Manufacturers of chip production put forward higher requirements for anti-static.
ESD protection is required inside every chip, but not every chip design company has an ESD protection expert. Maybe you didn't carefully consider the ESD protection problem during the design process, and finally the product test passed, but the potential ESD problem will cause the chip to fail (on the client side). Therefore, I strongly recommend that there be an ESD design plan in the early stage of the project. Chip designers typically add input protection to the connection area on the chip. These input protection networks provide a safe short circuit (usually to ground) to the substrate so that the chip will not be damaged by high voltages or large currents due to discharge. This technique has proven to be very effective in limiting the sensitivity of packaged semiconductor devices to ESD. The human body is one of the main static power sources, and the chip production workshop personnel and equipment need to have more stringent electrostatic protection measures. Operators who contact the chip must wear anti-static wrist straps, anti-static suits, anti-static shoes and other necessary static protection tools, and regular training.
Domestic professional ESD consulting services are rare. Here, we use the network as a platform for industry peers to communicate with each other. Although our existing experience is far from enough, we believe that our expertise is for engineers or companies with ESD design needs. It is all helpful. Our aim is not to profit but to accumulate experience. We have the passion to learn every aspect of ESD design. If you have related topics, including high-voltage ESD, SOI ESD, power device ESD, ESD design of ultra-bandwidth LNA, system-level ESD protection, etc., welcome to discuss with us.
