Semiconductor etching imposes strict requirements on the corrosion resistance, thermal stability, and optical purity of ...

Etching errors, such as residual layers, can affect the ability to further process and etch as well as hamper device performance. Thus, researchers use time-consuming and costly processes to ...

New method monitors semiconductor etching as it happens -- with light Peer-Reviewed Publication. University of Illinois at Urbana-Champaign, News Bureau ...

This method is low in cost, faster, and less noisy compared to the traditional methods, which also do not monitor the etching in progress. Moreover, the method is purely optical, hence there’s no ...

Energy-tunable XPS reveals accurate surface chemistry of Ti3C2Tx MXenes, correcting for adsorbates and improving ...

Now, a research group at Nagoya University in Japan has developed a new method called “wet-like plasma etching” that combines the selectivity of wet etching with the controllability of dry ...

The PEC etching-based technique marks a significant advancement of microdisk lasers. The scalable nature of the method, along with its sub-nanometer accuracy, opens up new possibilities for the myriad ...

PCB etching methods generally fall into one of two broad categories: wet and dry processes. For the home gamer, dry processes would include methods like milling out traces with a CNC router, ...
