RFID in Electronic Gas
Integral to everything from processors found inside smartphones or computers to memory chips and image sensors, the use of semiconductor chips or integrated-circuits is now spreading outside the digital world. The electronic gas plays a vital role for semiconductor chip quality.
The electronic gases family includes both pure gases and gas mixtures which are specially configured for specific manufacturing processes. Mass production of integrated circuits (IC) requires up to 30 different gases for the various processes involved. These operations, which are discussed in more detail below, include oxidation, deposition, etching, sputtering, doping, and inerting.
Batch number and expiry date are critical to electronic gas quality. Normally they are printed on the paper tag and pasted on the cylinder. Paper tags are not durable and easy to be stained, and soon be unreadable.
