SPRAY-ON LIQUID SILICON CHIPS

摘要

Researchers at Japan's Seiko Epson can ink-jet print crystalline silicon films of high enough quality for some microelectronics applications. They make it from a liquid silicon that can be coated onto a surface by spinning the surface to spread the liquid or by squirting the liquid from an ink-jet printer. Electronics manufacturing is an expensive business. Making microelectronic devices on silicon chips must be done in extremely expensive clean rooms. Layers of silicon and other semiconductors are deposited onto chips under high vacuum. Any slight contamination will ruin them.
