Quantum Dot Laser
An optically pumped nanocrystal quantum dot laser has been demonstrated by a group at MIT. The gain medium consists of nm-sized particles of CdSe coated with a layer of organic molecules and then immersed in a glassy film. The medium sits in a waveguide atop a grating. The fabrication advantage in this case derives from the fact that one uses simple solution processing rather than the technique of epitaxy usually needed for semiconductors.
[ + ]Nanospintronics
Physicists at the Institute for Microstructural Sciences (Ottawa) have created a prototype of a single-spin transistor, that consists of a quantum dot connected to spin-polarised leads.
[ + ]EMC Measurement Uncertainty Standard
The International Electrotechnical Commission have published CISPR 16-4, an international standard that describes how to apply electromagnetic compatibility measurement uncertainty when making a compliance statement by comparing test results to a limit.
[ + ]Electronic Taster
Scientist at Cardiff University in Wales are developing an alarm system that will provide warning of potentially harmful contamination in water supplies.
[ + ]LCD Manufacturing
Using the two company's joint venture, Philips Electronics and LG Electronics plan to expand capacity of LCD panels and large-screen desktop monitors. Production will begin in the first half of 2003.
[ + ]Single Atom Transistor Research
Scientist at Cornell University have created a transistor in which electrons flow through a single atom. This was achieved by implanting a "designer" molecule between two gold electrodes, or wires, to create a circuit. When voltage was applied to the transistor, electrons flowed through a single cobalt atom within the molecule.
[ + ]Ericsson and Infineon Partnership
Infineon will acquire the core business of Ericsson Microelctronics (MIC) making it a supplier of components for Ericsson in the areas of wireless infrastructure and mobile phones.
[ + ]Carbon Nanotube Technology
Scientists from Infineon Technologies in Munich claimed to have made a breakthrough in carbon nanotube (CNT) research. A microelectronics process was modified so that CNTs could be grown at predefined locations on 6" wafers. The properties of the CNTs, which include current densities up to 1010 A/cm2 and thermal conductivities almost twice that of diamond, can now be used in wafer-compatible processes for IC development . The features of CNTs have made them the material for future semiconductor technology with considerable increase in on-chip clock frequencies.
[ + ]GHz technology and RF businesses
Advance Power Technology RF (APT-RF) is a newly formed organisation and brand. It is the result of the integration of the RF businesses of APT and of two RF acquisitions, GHz Technology (January 2002) and Microsemi RF (May 2002).
[ + ]Chemical Engineers grow nanowires
A team of chemical engineers at the University of Louisville has developed a process for growing nanometer-scale wires that controls the tiny wires size, structure and composition.
[ + ]Optical Pea Shooter
Researchers from the University of Bath in England have propelled polystyrene beads through a hollow fibre with a laser beam.
[ + ]PCB Fabrication Industry
Morris Productions has ceased manufacturing PCBs and has entered into an agreement with Precision Circuits to manufacture PCBs.
[ + ]LCD FAB in Korea
Philips and LG have opened a fifth-generation thin-film transistor (TFT) LCD fabrication plant in Korea. Located in Kumi, South Korea, it will produce TFT-LCDs for 15 and 18 inch desktop monitors and 15 inch notebook PCs, as well as larger LCD TVs. The facility uses larger glass substrates (1000mm x1200mm).
[ + ]Hot Chips Coolant
The problem of computer generated heat is being researched by Hewlett Packard which is using inkjet technology by spraying cool streams of liquid onto the surface of semiconductor chips.
[ + ]Philips invents technology for paintable displays
Scientists from Philips have fabricated flat panel displays through simple coating techniques similar to painting. Philips claims that this makes displays cheaper, thinner and provides great design freedom.
