A precious metal is a rare metal chemical element of high economic value that occurs naturally. Chemically, the precious metals tend to be less reactive than most elements. Usually they are ductile and they have a high luster. Precious metals have historically been important as currency, but are now ...
Mechanical Grinding. Mechanical grinding is considered to be the most common technique because of its high thinning rate. It is a two-step process which involves coarse grinding and fine grinding. Fine grinding is crucial to get rid of the damage and surface irregularity brought about by the coarse grinding .
Silicon has dominated the semiconductor wafer market for more than three decades. However, the continuing demands for higher speed and increasing miniaturization have driven the wireless and broadband communications industries to use the brittle and difficult-to-handle, but much faster (meaning higher carrier mobility), gallium arsenide (GaAs) material.
Vertical gallium oxide Schottky barrier diodes with improved performance. Researchers based in the USA and Japan claim the highest Baliga figure of merit (FOM) of 0.6GW/cm 2 so far for β-phase gallium oxide (Ga 2 O 3) vertical Schottky barrier diodes (SBDs) [Noah Allen et al, IEEE Electron Device Letters, published online 29 July 2019]. The ...

Indium gallium arsenide (InGaAs) (alternatively gallium indium arsenide, GaInAs) is a ternary alloy (chemical compound) of indium arsenide (InAs) and gallium arsenide (GaAs). Indium and gallium are elements of the periodic table while arsenic is a element. Alloys made of these chemical groups are referred to as "III-V" compounds.
Grinding . Our grinders are designed to provide high reliability and consistent performance at a low cost of ownership. Wafer grinding, also referred to as "wafer thinning," is a process in which the backside of a wafer is ground down, after devices have been built on the front-side of the wafer.

Jul 01, 2008· The more recent constrained availability of Gallium during 2007, and the resultant price run-up, is an example of this intermittent volatility and does not reflect any long term concern about supply. As with many minor metals, the supply/demand balance of Gallium is difficult to fully track, and more difficult to forecast going forward.
In the context of manufacturing integrated circuits, wafer dicing is the process by which die are separated from a wafer of semiconductor following the processing of the wafer. The dicing process can involve scribing and breaking, mechanical sawing (normally with a machine called a dicing saw) or laser cutting.All methods are typically automated to ensure precision and accuracy.
