The chip starts out as a thin wafer of P-type silicon. This is then coated with a layer of silicon dioxide -- kind of a silicon rust, which doesn't conduct electricity. On top of this is placed a ...

T oday, silicon photonic circuits connect server racks and play key roles in chemical sensors, biosensors, and LIDAR for self ...

But although about 75% of the Earth is made from silica — or silicon dioxide (SiO 2), the main ... polycrystalline silicon used to make silicon wafers (smooth thin discs). The richness of ...

The narrow, deep holes required for one type of flash memory are made twice as fast with the right recipe, which includes a ...

Researchers at Osaka University in Suita, Japan, have devised a novel way to improve the performance of electronic devices. The study, published in ACS Applied Electronic ...

For that reason, the direct epitaxial growth of high-quality III-V optical gain materials selectively on large-size silicon photonics wafers remains a highly sought-after objective.” The large ...

Imec has demonstrated electrically-driven GaAs-based multi-quantum-well nano-ridge laser diodes fully, monolithically fabricated on 300 mm silicon wafers in its CMOS pilot prototyping line. Achieving ...
