Electron Free Plasma : From Being to Becoming
39,90 € *
ggf. zzgl. Versand

Electronegative plasmas produced by attaching mobile low energy electrons to create heavy negative ions are very attractive for both fundamental research and plasma processing applications. Electronegative gas plasmas are widely used in microelectronics manufacturing for etching and deposition of thin films. For example, plasmas in gases containing Cl2 or SF6 are used for silicon etching, fluorocarbon plasmas are indispensable for silicon dioxide etching, and oxygen plasmas are used for ashing of photoresist and other polymers. Electronegative plasmas produced in argon and sulfur hexafluoride (SF6) are used to etch silicon, silicon nitride, silicon carbide and titanium carbide with high etch rates and without film residues. Highly electronegative discharges, also called ion-ion plasmas are seen as a promising solution for electric propulsion and neutral beam development. Ion-ion plasmas find application in charge-free semiconductor manufacturing, negative ion sources, and the D-layer of the upper atmosphere. .Here based on CUSP type magntic filter, a source of an almost electron free plasma along with all possible mechanism of negative ion production is discussed.

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Tegal Corporation is a company in the semiconductor industry that manufactures plasma etch and deposition systems. Tegal was originally founded in 1972 by Ted Gallagher, hence its name. The company was acquired by Motorola in 1978 and sold some years later. Tegal has since went for IPO and is currently traded on NASDAQ under the ticker symbol TGAL. Michael Parodi was Chairman and CEO of Tegal for nearly a decade. "Tegal Corporation designs, manufactures, markets and services plasma etch and deposition systems that enable the production of IC memory and related microelectronics devices used in personal computers, wireless voice and data telecommunications, radio frequency identification devices (RFID), smart cards, data storage and nano-scale actuators. Etching and deposition constitute two of the principal IC and related device production process steps and each must be performed numerous times in the production of such devices.

Photogravure
29,00 € *

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Photogravure registers a wide variety of tones, through the transfer of etching ink from an etched copper plate to special dampened paper run through an etching press. The unique tonal range comes from photogravure''s variable depth of etch, that is, the shadows are etched many times deeper than the highlights. Unlike half-tone processes which merely vary the size of dots, the actual quantity and depth of ink wells are varied in a photogravure plate and are often blended into a smooth tone by the printing process. Photogravure practitioners such as Peter Henry Emerson and others brought the art to a high standard in the late 19th century. This continued with the work of Alfred Stieglitz in the early 20th century, especially in relation to his publication Camera Work. This publication also featured the photogravures of Alvin Langdon Coburn who was a fine gravure printer and envisioned his photographic work as gravures rather than other photo-based processes.

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Roedy Green (born Munroe Frederic Compton Green on February 4, 1948) is a Canadian programmer, independent computer consultant, and activist. He is well-known on the Internet for his Java & Internet Glossary, and his popular essay How to Write Unmaintainable Code. Roedy began his programming career in 1963 (at the then unheard-of age of 15), writing Fortran timetable scheduling software for the West Vancouver Secondary School. In August 1969, he came out as gay. In 1971, based on his experiences, he self-published the booklet "A Guide For The Naive Homosexual" (also known as "the blurb"), and became involved in the founding of the Gay Alliance Toward Equality (GATE), later serving as its second chairman (August 1971 to July 1972). In 1979, he worked with John C. Lilly on Project JANUS, writing hardware interface software and a dolphin-controlled Etch-A-Sketch. Later, as part of volunteer work for The Hunger Project, he created the programming language Abundance.

The Ueda Domain was a Japanese domain of the Edo period, located in Shinano Province (modern-day Ueda, Nagano). Shinano Province is an old province of Japan that is now present day Nagano Prefecture. Its abbreviation is Shinsh . Shinano bordered on Echigo, Etch , Hida, Kai, K zuke, Mikawa, Mino, Musashi, Suruga, and T t mi Provinces. The ancient capital was located near modern-day Matsumoto, which became an important city of the province. The World War II era Japanese aircraft carrier Shinano was named after this old province.

Reactive-ion Etching
34,00 € *
ggf. zzgl. Versand

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Reactive ion etching (RIE) is an etching technology used in microfabrication. It uses chemically reactive plasma to remove material deposited on wafers. The plasma is generated under low pressure (vacuum) by an electromagnetic field. High-energy ions from the plasma attack the wafer surface and react with it. A typical (parallel plate) RIE system consists of a cylindrical vacuum chamber, with a wafer platter situated in the bottom portion of the chamber. The wafer platter is electrically isolated from the rest of the chamber, which is usually grounded. Gas enters through small inlets in the top of the chamber, and exits to the vacuum pump system through the bottom. The types and amount of gas used vary depending upon the etch process, for instance, sulfur hexafluoride is commonly used for etching silicon. Gas pressure is typically maintained in a range between a few millitorr and a few hundred millitorr by adjusting gas flow rates and/or adjusting an exhaust orifice.

Med Port
21,90 CHF *
ggf. zzgl. Versand

The stunning opening of the Med Port in Tangier, Morocco in 2012 as the largest sea port and free market area in the Mediterranean is the focus of this fast-paced novel that shows the Med Port to be as much a hot seat of international intrigue in the 21st Century as it was when caravans crossed the desert. Mosques, dark alleyways, and a region and culture ripe with historical drama, lead to a transatlantic sailing to the Med Port and a visit to the Legation House in Morocco-the only U.S. National Landmark outside the U.S. borders. Curious? ABSOLUTELY! Though a work of fiction, MED PORT weaves together a thread of plausibilities from news items and historical data, to create a realistic story that spans the lives and eras of John Paul Jones, George Washington, WWII, the Cold War, and the Space Lab. The suspenseful, intricate, 400-year-old trail is pieced together when two aging Cold War spies-once Russian and American counterparts-are called by their nations to team-up to find a way to stop a devastating point of national embarrassment for the United States from becoming a bargaining chip used by the Chinese to overthrow the global financial markets. In these carefully crafted pages, kings, presidents, old friends, murder, love, intrigue, history, and the environs and city of the Med Port etch their presence vividly into the reader's imagination.
