Intel claims quantum leap in fibre-optic detectors
News However, Intel claims to have found a way to create photodetectors using cheap silicon doped with a small layer of the element germanium, drastically reducing cost. Intel has developed silicon-based photoelectric detectors that could cut the cost...

The Technological Singularity
Blog Comment The answer to controlling AI beings from replicating or improving themselves would be to keep them out of the semiconductor foundries, sand pits (silicon dioxide becomes feedstock for the foundries), metal mines (gold, silver, aluminum, copper...

The transistor turns 60
News Although other elements and materials, such as germanium, have been used to make transistors, silicon has been the favourite. All the components are made out of a single piece of silicon, rather than assembled transistor by transistor.

60 GHz networking, the story so far
Blog SiBeam's schtick is that it can make its chips out of ordinary silicon using reasonably normal CMOS techniques (guess who's hoping to be snapped up by Intel), while IBM is working with silicon-germanium.

AMD starts shipping its 65nm chips
News In the N-channel transistors, which carry negative electrons, germanium spreads out the lattice of the silicon; electrons flow more freely — a comparison would be a deer running through a forest that's been thinned of trees.

Chip breaks speed record in deep freeze
News The experiment is part of a project to explore the ultimate speed limits of silicon-germanium (SiGe) chips. SiGe chips are similar to standard silicon chips, but they also contain germanium for better performance and lower power consumption.

Intel, ST get together for the memories
News PCM uses energy switched by an ordinary transistor to heat up a tiny amount of chalcogenide alloy, a mixture of antimony, germanium and tellurium also used in CD-RW and DVD-RAM disks. PCM uses a combination of standard silicon chip techniques and...

A High Average-Efficiency SiGe HBT Power Amplifier for WCDMA Handset Applications
White Papers The linearity of a Silicon-Germanium (SiGe) HBT Power Amplifier (PA) is analyzed with the help of a power-dependent coefficient Volterra technique. The effect of emitter inductance is included and the dominant sources of nonlinearity are identified.

Intel's high-powered engineers create low-power chips
News Another important part of the transistor's design is that some of its silicon is put under strain by making it sit next to layers of different material - silicon germanium or a silicon nitride - which have atoms arranged at a different spacing to...
