Views Read Edit View history. Naturally, a GaAs surface cannot withstand the high temperatures needed for diffusion; however a viable and actively pursued alternative as of the ‘s was ion implanation.

Mechanical Specifications Gallium arsenide can be supplied as ingots or ingot sections or as-cut, etched or polished wafers.

GaAs – Gallium Arsenide – Epitaxy Ready Polished Wafers: Wafer Technology

I have an enquiry from a customer but I hear the stuff, although not intrinsicaly toxic, can libreate Arenic and Gallium compounds which, when in contact with water, acids or alkalais can give off nasty stuff. Rinse mouth with water.


Uses advised against no data available 1. Mscs term exposure limit LC Also many solar cars utilize GaAs in solar arrays.

The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace. Anyone machined this stuff? Monitor for pulmonary mwds and treat if necessary Do not discharge to sewer systems.

Do not contaminate water, foodstuffs, feed or seed by storage or disposal. For eye contamination, flush eyes immediately with water.

Gallium arsenide – Wikipedia

If not breathing, give artificial respiration. Semiconductor Devices Physics and Technology.

gaa Overall summary evaluation of carcinogenic risk to humans is Group 1: Never give anything by mouth to an unconscious person. Anticipate seizures and treat if necessary Consequently, GaAs thin films must be supported on a substrate material. The second major advantage of Si yaas the existence of a native oxide silicon dioxideSiO 2which is used as an insulator.

Such a layer is relatively robust and easy to handle. Accidental release measures 6.



Silicon has three major advantages over GaAs for integrated circuit manufacture. The economies of scale available to the silicon industry has also hindered the adoption of GaAs. In case of skin contact Wash off with soap and plenty of water. Containers can be triply rinsed or equivalent and offered for recycling or reconditioning. P Do not handle until all safety precautions have been read and understood. Attacked by cold concentrated hydrochloric acid.

This has made it an ideal material for monolithic microwave integrated msdz, MMICswhere active and essential passive components can readily be produced on a single slice of GaAs. Avoid contact with skin and eyes.

Gallium arsenide

Oxidation of GaAs occurs in air and degrades performance of the semiconductor. This method produces crystals with a much lower dislocation density than those produced by any other growth method. Follow us on All times are GMT On a more practical level, it’s also very brittle.
