A method for singulation of thick GaN wafers (, 300400 um) through the use of a doubleside laserscribe process. In a preferred embodiment, the patterned GaN substrate is processed using a laserscribe on each side of the substrate to form scribe lines. The scribe lines are aligned to each other. In a preferred embodiment, the substrate has not been subjected to a thinning or polishing ...

Jul 01, 2008· The more recent constrained availability of Gallium during 2007, and the resultant price runup, 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.
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 "IIIV" compounds.
