The semiconductor market, a $300B+ industry driven by strong demand for IT, sensors and consumer devices, is extremely competitive with a heavy focus on R&D to make chips smaller, faster and more functional, as well as cost effective for high volume manufacturing. Denton Vacuum supports businesses focused on sensors, MEMS (microelectromechanical systems), and compound semiconductors in this ever-emerging market.
Silicon semiconductors are used in virtually every electronic device and component, but compound semiconductors are growing globally as well. They are critical in optical applications like light-emitting diodes (LEDs), photodetectors, IR detectors and focal plane arrays. Some, like focal plane arrays, are low-throughput applications. Due to growing consumer demand, many of these applications, such as RF power transistors in cell phones, require high-volume manufacturing.
Common semiconductor coating applications include contact coating, gold coating, under bump metallization, DLC (diamond-like carbon), barrier overcoats, and sensors, including piezoelectric and precision alloys. When selecting a material to use for coating, you’ll want to consider the lifespan of the material, the environment that the semiconductor will perform in, the potential damage you’ll want to protect against, material cost and, in some cases, aesthetic appearance.
Compound semiconductor production also requires a thin film deposition system configuration that meets high-throughput needs while providing excellent process performance. For high-volume manufacturing, system uptime and reliability are crucial factors. When selecting a thin film system, you should look for a configuration that’s compatible with in-situ controls and an automated front-end option for maximum scalability and repeatability.
