6 FAQs about [Laser battery silicon wafer]
How do lasers work on silicon wafers?
Emily Cooper A straightforward way of directly integrating lasers on silicon wafers is a chip-packaging technology called flip-chip processing, which is very much what it sounds like. A chip’s electrical connections are on top where the uppermost layer of interconnects terminate on metal pads.
What is wafer-scale laser characterization?
Wafer-scale laser characterization was carried out using a 300-mm semi-automated wafer probe station fitted out with a temperature controller and a MMF to collect the laser emission, enabling the measurement of thousands of devices on a single wafer at high throughput.
What is III-V-to-silicon-wafer bonding?
But one technique, a form of what’s called III-V-to-silicon-wafer bonding, finds a way around that. Instead of transferring already-constructed lasers (or other light-emitting components) to a processed silicon wafer, this scheme bonds blank dies (or even small wafers) of a III-V semiconductor to that silicon wafer.
Can gallium arsenide be used to make laser wafers?
Notably, the authors deposit the gallium arsenide using a technique that is widely used for the high-volume production of semiconductor laser wafers, and which could be readily adopted for industrial-scale manufacturing of these devices.
How can lasers and silicon be integrated?
There are many ways to achieve this tighter integration of lasers and silicon. Working at Imec, a Belgium-based nanoelectronics R&D center, we are currently pursuing four basic strategies: flip-chip processing, microtransfer printing, wafer bonding, and monolithic integration.
