Semiconductors: Fabrication & high purity gases

What is a semiconductor? The typical semiconductor device is a complex array of transistors and integrated circuits that work in unison to provide the functionality of our computers, cell phones, televisions, automobiles and every other electronic device that we have become so dependent upon for our daily activities. How are semiconductors made? It involves multiple … Continued

Valves: Finding the right one for your cylinders

How do you find the right valve for your cylinder?   We take the following information into account:   Which gas is in the cylinder? Different gases react with different materials, and therefore valves must be chosen appropriately from materials like brass, chrome, stainless steel, Monel (nickel-copper alloy), or Hastelloy (nickel-molybdenum-chromium alloy). Valve outlets are … Continued

Sulfur Hexafluoride (SF6): Its importance to the electrical industry

Using SF6 The majority of all SF6, 80 percent or more, is used as a dielectric insulator in GIS (Gas Insulated Systems) in high voltage (anything above 72.5 kV) electric distribution systems. SF6 offers dielectric strength (it rapidly quenches electrical discharges), chemical stability during electrical operations, excellent thermal conductivity, and easy synthesis. SF6 was discovered in 1901; before … Continued

Octafluoropropane: the potential and future of C3F8

About octafluoropropane Octafluoropropane (also known as C3F8 and halocarbon 218) is made by either chemical fluorination or by a procedure known as the Fowler process, which was created in World War II to develop enough coolant liquid for uranium enrichment. There are no natural sources.   Applications of octafluoropropane In the semiconductor industry it is … Continued

Butane: Its value to the Cannabis industry

About butane Butane (C4H10) is a liquefied petroleum gas, available from Electronic Fluorocarbons in every weight from 6 pounds to half a ton. A flammable gas (hazard class 2.1), butane will burn at a temperature of about 1700° Kelvin (about 1426°C), hot enough to melt aluminum and vaporize some organic compounds—hence, its use in torches. … Continued

Neon: It’s more than a flickering motel sign

The bright orange glow of a neon sign is easy to spot (NAICS 339950/3993); in fact, neon (Ne) was recognized as a new element precisely because of its bright red emission spectrum. But even though neon signs have become harder to find, neon is still used in lighting (NAICS 335110)—for example, as the pilot light … Continued

Xenon Gas: Industrial and Commercial Uses

Customers in the semiconductor, lighting, medical, and research industries are very familiar with xenon gas and its many uses. But because of its rarity, an estimated 87 ppb (parts per billion) in the atmosphere, xenon is expensive, which means that it has many more potential uses that are not yet economically feasible. As manufacturing costs … Continued

Hexafluoro-1,3-butadiene (C4F6) Gas Spotlight

Hexafluoro-1,3-butadiene (C4F6) is a colorless, odorless, flammable liquefied gas. Years of research have shown that C4F6 (H-2316) presents several advantages for dry etching of oxide-based materials:    It has a higher etch rate and selectivity than octafluorocyclobutane (c-C4F8 – H318), another extensively used etchant for silicon oxide. Unlike C4F8 (H318), with C4F6 (H2316), only the … Continued

Hexafluoroethane Gas Spotlight

Hexafluoroethane also known as Halocarbon 116, or perfluoroethane is a stable, nontoxic, nonflammable gas that is essential to three very different industries: semiconductor and microsystem manufacturing, refrigeration, and medical. In each industry, buyers appreciate different characteristics of the gas, but in both manufacturing and medical, purity is the greatest concern. Where to buy? Electronic Fluorocarbons … Continued

Tetrafluoromethane Gas Spotlight Blog

A colorless, nonflammable gas, tetrafluoromethane-also known as halocarbon 14 or carbon tetrafluoride- is known as the simplest fluorocarbon because it consists of one carbon atom in the middle that binds to four fluorine atoms around the outside (CF4). However, its uses are anything but simple. CF4 has a very low boiling point (‑128°C, ‑202°F), defining it … Continued
