In this technique, fluorine-based plasma chemistry is used for silicon etching, which is combined with a fluorocarbon plasma process to offer sidewall passivation and enhanced selectivity to masking ...

Plasma etching is a cornerstone technique in semiconductor fabrication, enabling the precise removal of material layers through the use of ionised gases. This process is essential for fabricating ...

After more than a decade of research and development, Tokyo Electron Miyagi Ltd. has introduced an innovative semiconductor etching method that achieves etch rates up to five times faster than ...

A team of physicists has uncovered some of the physics that make possible the etching of silicon computer chips, which power cell phones, computers, and a huge range of electronic devices. Physicist ...

Ion beam expertise is critical to delivering the manufacturing tolerance required for these gratings. Oxford Instruments Plasma Technology has developed a technology to allow optical designers to ...

After years in R&D, a technology called cryogenic etch is re-emerging as a possible option for production as the industry faces new challenges in memory and logic. Cryogenic etch removes materials in ...

In dry etching, the trajectory of accelerated ions is non-uniform and non-vertical, due to collisions with gas molecules and other random thermal effects (figure 1). This has an impact on etch results ...

An example of directional etching for nanohole arrays of less than 500nm in diameter. (Image: A*STAR Institute of Materials Research and Engineering) Wet etching can be classified into two main types ...
