OSAKA, Japan — Mitsubishi Electric Corp. has developed a single-step, hydrofluoric acid electrochemical etching process that can achieve an aspect ratio greater than 60:1 at potentially a tenth of the ...

Researchers etch nano-sized textures and add copper ions to create a naturally antibacterial material for hospitals and other shared settings. Postdoctoral scholar Anuja Tripathi examines a small ...

As any good metallurgist will tell you, you can't just take any two types of metal and weld them together. You may instead be able to just join them together with glue, however, thanks to research ...

The fundamentals of a good Bosch etching system are described below; There are a number of significant features of the equipment used for Bosch processing which differ from normal ICP systems: In ...

In today's industries, quality inspection in semiconductor manufacturing is critical. Many traditional fault detection and diagnosis techniques have been developed to determine the existence of trends ...

For maximum resolution in a scanning tunneling microscope (STM), an extremely sharp metallic tip is required, which serves as the point through which the STM “scans” a sample. A blunt tip reduces STM ...

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 ...
