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.

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.

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 ...

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

Tiger Group and GESemi are now accepting offers for advanced equipment used to produce high-efficiency, gallium arsenide ...

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 ...
