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 ...

Etching is a method employed during the fabrication of semiconductors to chemically remove layers from the surface of the wafer substrate. Etching is a crucial process, and each wafer is subject to ...

The ADE tool applies the texture to only one side of the wafer, facilitating integration of the technology into a PERC process by providing surface decoupling without any additional ...

Major processes in semiconductor wafer fabrication: 1) wafer preparation, 2) pattern transfer, 3) doping, 4) deposition, 5) etching, and 6) packaging. The process of creating semiconductors can be ...

Researchers at the Solar Energy Research Institute of Singapore (SERIS) at the National University of Singapore (NUS) have announced the development of a significantly low-cost technique to texture ...

With advances in new technology it is getting more important to monitor all aspects of the influencing parameters in critical etch steps and utilize them as tuning knobs for within-wafer uniformity ...

AZoMaterials interviews Matt Wilding about how the EP-Replayer enables users to simulate previous etch runs in real time, helping them optimize End Point detection methods, and more. Can you start by ...

Etching is a process that removes unwanted material from a wafer, which is also known as a "slice" or "substrate." Wafers are made of semiconducting material such as crystalline silicon and are used ...
