A team led by Washington State University has successfully recreated a millennia-old pigment first synthesized in ancient ...

A team of Washington State University-led researchers has recreated the world's oldest synthetic pigment, called Egyptian ...

SOI wafers incorporate an ultra-thin layer of silicon separated from the bulk substrate by an insulator (typically silicon dioxide), dramatically reducing parasitic capacitance and improving thermal ...

CO2 is a natural part of the planet, but too much has tipped the climate scales. Carbon dioxide may be a naturally occurring substance on Earth, but too much of its presence has contributed to ...

pH-controlled selective etching has become a game-changer, enabling the removal of silicon dioxide with selectivity ratios exceeding 300:1. These advancements allow for the self-limiting termination ...

Phosphorus trifluoride acted as a nitrous boost for silicon dioxide etching, quadrupling the rate. They also tested ammonium fluorosilicate. The team detailed its findings in a study published in ...

The researchers also found that adding phosphorus trifluoride quadrupled the etch rate for silicon dioxide, though it only marginally increased the silicon nitride etch rate. They also investigated ...

The researchers also studied the impact of phosphorus trifluoride, an essential ingredient when etching silicon dioxide at any significant degree. While it has been used before, the researchers wanted ...

The narrow, deep holes required for one type of flash memory are made twice as fast with the right recipe, which includes a plasma made from hydrogen fluoride. To ...

The researchers also studied the impact of phosphorus trifluoride, an essential ingredient when etching silicon dioxide at any significant degree. While it has been used before, the researchers ...

Abstract: This paper introduces a novel and simple etching technique that utilizes a mixture of sulfuric acid (H2 SO4) and hydrofluoric acid (HF). This method selectively etches silicon dioxide (SiO2) ...
