Drypoint is a printmaking technique of the intaglio family, in which an image is incised into a plate (or "matrix") with a hard-pointed "needle" of sharp metal or diamond point. In principle, the method is practically identical to engraving .
Dry etching is used in conjunction with photolithographic techniques to attack certain areas of a semiconductor surface in order to form recesses in material.. Applications include contact holes (which are contacts to the underlying semiconductor substrate), via holes (which are holes that are formed to provide an interconnect path between conductive layers in the layered semiconductor device ...
Etching by goldsmiths and other metal-workers in order to decorate metal items such as guns, armour, cups and plates has been known in Europe since the Middle Ages at least, and may go back to antiquity. The elaborate decoration of armour, in Germany at least, was an art probably imported from Italy around the end of the 15th century—little ...
Drypoint and etching were also German inventions of the fifteenth century, probably by the Housebook Master and Daniel Hopfer respectively. [14] [15] In the 15th century, woodcut and engraving served to produce both religious and secular imagery. One of the most popular secular uses of engraver's art was in the production of playing cards, a ...
Etching is a critically important process module in fabrication, and every wafer undergoes many etching steps before it is complete. For many etch steps, part of the wafer is protected from the etchant by a "masking" material which resists etching. In some cases, the masking material is a photoresist which has been patterned using photolithography.
The term usually refers to the arts that rely more on line, color or tone, especially drawing and the various forms of engraving; [2] it is sometimes understood to refer specifically to drawing and the various printmaking processes, [2] such as line engraving, aquatint, drypoint, etching, mezzotint, monotype, lithography, and screen printing ...
Reactive-ion etching (RIE) is an etching technology used in microfabrication. RIE is a type of dry etching which has different characteristics than wet etching . RIE uses chemically reactive plasma to remove material deposited on wafers .
According to Brekle, the applied printing technique has much in common with the later method of drypoint etching, by which an image is incised into a copper plate; however, unlike drypoint, MS 5236 is a colourless blind print. [6]
