Gallium nitride (GaN)-based high electron mobility transistors (HEMTs) are a type of field-effect transistors (FETs) designed to operate at very high frequencies with low noise. As such, they have ...

Thin film technology focuses on the deposition and analysis of functional material layers on a substrate. These layers are essential building blocks in modern devices, like the microchips found in ...

Mars just gave up one of its oldest secrets — and it took a decade, a spacecraft, and a cosmic cannonball to catch it in the act. For the first time, NASA’s MAVEN mission has directly observed a ...

Sputtering targets are the source materials for the preparation of sputtered thin films. In particular, high-purity sputtering targets are used in the physical vapor deposition (PVD) process for the ...

The confocal sputtering technique involves the arrangement of magnetrons inside a vacuum chamber so that it is possible to apply multiple materials onto the substrate without breaking vacuum. This ...

This video shows SemicoreEquipment's sputtering manufacturing process. This process starts when a substrate to be coated is placed in a vacuum chamber containing an inert gas. The negative charge is ...

“You can never be too rich or too thin,” the saying goes, and when it comes to coatings, it’s true that thinner is often better. The way to truly thin coatings, ones that are sometimes only a few ...
