Over the past decade, the semiconductor manufacturing industry has used hydroxylamine solutions in cleaning formulations to strip process residues from integrated circuit devices. Hydroxylamine and its derivatives are also used in the manufacture of nylon, inks, paints, pharmaceuticals, agrochemicals, and photographic developers. 

Silicon is very important to the semiconductor manufacturing industry. The three naturally occurring isotopes of silicon are silicon-28, silicon-29, and silicon-30. Write the symbol for each. 

The semiconductor manufacturing industry uses a number of hazardous specialty gases such as phosphine (PH3), arsine (ASH3) and boron trifluoride (BF3) for doping, etching, and thin-film deposition. These gases are highly toxic and py-...

These advantageous features have been demonstrated in the continuous operation of plasma deposition and plasma etching processes in semiconductor manufacturing industry. 

Specialty gases are another important and growing segment of the compressed gas industry. The semiconductor manufacturing industry uses specialty gases such as silane in very pure form to manufacture the microchips that are the brains of all sizes of computers.

Our lives have been, and continue to be, revolutionized by electronics that impact the way we work, treat patients, communicate, shop, travel, bank, and learn. The driving force of these changes has been the semiconductor manufacturing industry (semicon). It has rapidly renewed itself by improving the state of technology and reducing the cost of its products. Nearly every two years there has been a step change towards smaller, faster, and less costly semiconductor devices (chips). 

The advantages of miniaturization are now being exploited in areas beyond microelectronics. Adaptation of materials and processes originally devised for semiconductor manufacture has allowed fabrication of sensors (for example, pressure meters and accelerometers used in the automotive industry) (6,7), complex optical (8) and micromechanical (6,7,9) assembHes, and devices for medical diagnostics (6,7,10) using Hthographic resists. 

Process safety management has been applied primarily in the chemical process industries. However, the concepts of PSM, and the approaches used for implementing PSM, can be applied equally well to any manufacturing process that uses chemical products. Manufacturing industries as diverse as semiconductor manufacturing 2md food processing can, and do, apply PSM to improve safety and operations. 

In a modern industrialised society the analytical chemist has a very important role to play. Thus most manufacturing industries rely upon both qualitative and quantitative chemical analysis to ensure that the raw materials used meet certain specifications, and also to check the quality of the final product. The examination of raw materials is carried out to ensure that there are no unusual substances present which might be deleterious to the manufacturing process or appear as a harmful impurity in the final product. Further, since the value of the raw material may be governed by the amount of the required ingredient which it contains, a quantitative analysis is performed to establish the proportion of the essential component this procedure is often referred to as assaying. The final manufactured product is subject to quality control to ensure that its essential components are present within a pre-determined range of composition, whilst impurities do not exceed certain specified limits. The semiconductor industry is an example of an industry whose very existence is dependent upon very accurate determination of substances present in extremely minute quantities.

Nanotechnology is expected to impact all current industries including semiconductors, manufacturing and biotechnology, and it may also create several new ones. Major challenges remain, before these opportunities can be realised and some of them include the... 

While industrial benchmarks clearly indicate that pharmaceutical manufacturers have many opportunities to improve quality control, direct comparison with other industries may be somewhat misleading. As opposed to such industries as semiconductor manufacturing, where defective parts are often readily apparent at some...
