	etching. The Columbia Encyclopedia, Sixth Edition. 2001-05
		In hard-ground etching the plate, usually of copper or zinc, is given a thin coating or ground of acid-resistant resin.
		Soft-ground etching gives effects similar to those obtained in pencil or crayon drawing, while aquatint approximates the effects of a wash drawing.
		Both seem to have originated in Germany, where Dürer’s etchings on iron, made between 1510 and 1520, were probably the earliest important examples of an art that in the following centuries was practiced by many of the greatest draftsmen and painters.

	Professional Glass Consultants: What is glass etching?
		All etched elements have to be separated by spaces of unetched glass, or the etched elements blend together as a single silhouette, with no detail inside the border.
		Surface etching is the easiest technique to learn and the fastest way to produce a finished etching on glass.
		But unlike surface etching, the elements in the design are blasted to different apparent shades of gray (hence the name Shading), rather than to the solid white color produced in surface etching.

	Photoelectrochemical etching of semiconductors
		In PEC etching, the potential of the semiconductor is controlled by a power supply or by an oxidizing agent in the case of an electroless process.
		The role of water in the formation of surface oxides was addressed by Propst and Kohl by use of nonaqueous solvents in the PEC etching and dissolution of silicon [60,61].
		Thus, it is possible to etch silicon with oxide present, or to use silicon dioxide as an etch mask for PEC etching.

	Etching - Wikipedia, the free encyclopedia
		Etching is an intaglio method of printmaking in which the image is incised into the surface of a metal plate using an acid.
		Etching is also used in the manufacturing of printed circuit boards and semiconductor devices and the preparation of metallic specimens for microscopic observation.
		Zinc is also used, because as a softer metal, etching times are shorter; however, that softness also leads to faster degradation of the image in the press.

	Etching
		The byproducts are absorbed by the etch chamber.
		In a plasma reaction, the etching process is controlled by two factors: the type of plasma discharge (inert or reactive) and the amount of bombardment.
		Plasma etching consists of: a plasma chamber, where the wafer is placed; a radio frequency power source, this helps the plasma to breakdown the silicon; a gas flow control system, to deliver the plasma; and a vacuum system to remove the waste gas.

	Plasma Etching - Anatech LTD
		Similarly, plasma etching has grown from the use of relatively simple, parallel-plate configurations for a variety of films, to million-dollar modular chambers with multiple frequency generators, electrostatic chucks, externally controlled wall temperatures, and a variety of process control sensors designed specifically for one type of film.
		Etch selectivity to different films is also essential, since resist material is occasionally inadequate to provide a sufficient mask for features which must be etched.
		To etch a Si trench, for example, an oxide layer must be defined as a mask for the Si, since the presence of organics during trench etching can degrade process performance.

	dbanks - Wet Etching - Microengineering Intro
		Wet etching is a blanket name that covers the removal of material by immersing the wafer in a liquid bath of the chemical etchant.
		The KOH etches the silicon that is not protected by the mask, and etches around the boron doped silicon (figure 4d).
		With complex designs, etching the wafer from the front in KOH may cause problems where slow etching crystal planes prevent it from etching beneath the boron doped silicon.

	Rembrandt and the Technique of Etching
		The chemical technique of etching was developed in the Middle Ages by Arabic armouries as a means of applying decoration to weapons.
		The etchings in the Rembrandt House collection cited as examples are described in the catalogue section 1.
		He can add or deepen lines by etching the plate again or by using the drypoint, but etched lines can also be erased: shallow ones by rubbing them with a burnisher so that the burr and the sides are pushed into the groove, deep ones by scraping with a scraper.

	Etching Processes
		Anisotropic processes allow the etching to stop on certain crystal planes in the substrate, but still results in a loss of space, since these planes cannot be vertical to the surface when etching holes or cavities.
		By changing the balance it is possible to influence the anisotropy of the etching, since the chemical part is isotropic and the physical part highly anisotropic the combination can form sidewalls that have shapes from rounded to vertical.
		The material to be etched is dissolved at the surface in a chemical reaction with the gas molecules.

	Etching Copperclad Substrates
		While some mechanical etch vendors offer manual and semi-automatic machines for inserting eyelets into all of the designated through-holes, the cost of the equipment, the penalty in PCB real-estate (holes must be drilled oversized to accommodate the eyelets), and the relative sluggishness of the process render it undesirable for many applications.
		The primary downside of bubble etching is that it generates a significant quantity of corrosive aerosol.
		While the board is cooling, etch a test coupon and record the time (T) required to etch the board clear (without damaging the copper protected by the resist).

	Sample Preparation - Etching
		Chemical etching is based on the aplication of certain illumination methods, all of which use the Kohler illumination principle.
		In precipitation etching the material is first dissolved at the surface; it then reacts with certain components of the etchant to form insoluble compounds.
		Etching time and temperature are closely related; by increasing the temperature, the time can usually be decreased.

	Surface science issues in plasma etching
		The photoemission intensity obtained from the etched silicon nitride sample is higher than that from the silicon dioxide sample, indicating that the fluorocarbon film on the nitride surface is thicker than on the oxide surface [36].
		In Figure 8 the etching rates of oxide and silicon nitride at a self-bias potential of -100 V are plotted as a function of fluorocarbon film thickness and are compared to silicon etching under the same conditions.
		To examine the etching behavior and surface chemistry as a function of angle in a controlled fashion, V-groove structures were prepared by highly anisotropic wet etching of silicon substrates [41].

	Burn Out Fabrics - Sew News Magazine--Seein' it Through (Fabric Etching) (Site not responding. Last check: )
		Burnout and etched effects can be achieved when the chemical is applied to fabrics that have fiber blends: cellulose fibers blended with wool, silk or synthetic fibers.
		For example, fabric woven with rayon fibers in the weft and silk fibers in the warp will yield an etched design with the fibers left running in only one direction; this result is satisfactory and interesting for small design areas, but will appear as holes in larger areas.
		The etching technique is essentially the same for velvet, with a few additional considerations.

	BYU Cleanroom - RIE Etching
		A disadvantage of wet etching is the undercutting caused by the isotropy of the etch.
		The etching ions are accelerated into the etching region, where they combine with silicon dioxide and then are dispersed.
		Because the electric field accelerated ions toward the surface, the etching caused by these ions is much more dominant than the etching of radicals - ions traveling in varied directions, so the etching is anisotropic.
