The word 'etching' is correct and is commonly used in written English.
Etching is a noun that refers to a technique for engraving or printing designs on metal, glass, or other materials by covering it with a protective layer and then using acid to cut into the exposed parts to create a design. Example: The artist created a beautiful etching of a cityscape on a copper plate and then printed it onto high-quality paper. The etching showed intricate details and shading, demonstrating the artist's skill in this technique.
Instead, Dr Parviz uses a technique he developed the year before last, and for which this is the first application.In this section Nearly there Eyeing up a new technology A successful mixture Face value ReprintsIt works by etching small, precisely shaped holes in the PET.
By etching microscopic components into the surface of silicon wafers, researchers are building Lilliput-sized engines that work just like their full-sized brethren.
These data can be cloned, as when someone's fingerprints are "skimmed" from something he has touched and replicated (or "spoofed" in the jargon), for example by etching a print onto a jelly mould.
One company selling hydrochloric acid for etching cement floors reckoned that, because it was in gel form and could legally be washed down the drain, the product was environmentally friendly.
The remaining profitable lines range from binoculars and spectacles 40,000 lenses a day are made at Aalen, near Oberkochen to monster combinations of quartz lenses, taking months to make, assemble and calibrate, that focus laser beams etching ultra-fine patterns on to semiconductors.
In 1959, two groups separately realised that instead of painstakingly making transistors one at a time, many of them could be created at once by etching conducting pathways on a wafer of silicon, which had the necessary electrical properties.This paved the way for the modern computer.
To do so, they employed the standard chipmaking techniques of depositing chemicals on the wafers, then etching in patterns using solvents.
They will have to come up with a successor to photolithography (the current method of etching designs on to silicon), which cannot cope with details less than about half of the current size.
"Staying at home is a bum it's so boring," he says, etching his long record of unsuccessful job applications onto a form.
Paradoxically, modern artists are taking their digital recordings and etching them to new LPs.Vinyl has seen a resurgence over the past few years, and that trend has continued.
But the metal interconnections are then made by etching microscopic trenches in the insulating substrate and filling them in with a conducting metal.
