Consequently, a gallium arsenide wafer, or substrate, is semi-insulating, whereas a silicon wafer is semi-conducting. Gallium arsenide also offers a wider range of operating temperatures than silicon ...

In 2001, Motorola developed a technique that places a spongy layer between gallium arsenide and silicon on the same wafer. Combining these two materials yields a higher-speed product at a lower cost.

Hundreds of decommissioned manufacturing tools from Ubiquity Solar, including semiconductor and photovoltaic production lines ...

Gallium arsenide is then deposited into these trenches ... V nano-ridge engineering concept to demonstrate the first full wafer-scale fabrication of electrically pumped GaAs-based lasers on ...

The most optimal material for solid-state lasers in photonics is gallium-arsenide (GaAs), but due ... grown on industry-standard 300 mm silicon wafers. The trick was to accept the lattice mismatch ...

Engineers can bond gallium arsenide dies or small wafers to silicon waveguides, then build the lasers on top, a process that requires specialized equipment and results in material waste.

but its parent Sino-American Silicon's sales dipped 1% due to slowdown in gallium arsenide operations. Gross margin of both firms improved marginally to 30% as silicon wafer factory utilization ...

Its product mix consists of indium phosphide (InP) wafers, gallium arsenide (GaAs) wafer substrates, and single-element substrates made from germanium (Ge). Its wafer substrates are manufactured ...

Also available are patents (nearly 200 in all) and intellectual property (IP) assets related to the high-tech manufacture of gallium arsenide wafers. "With its PV technology products, Ubiquity Solar ...
