In the semiconductor world until recently, silicon
strain was a phenomenon to be shunned.
The first paper outlines the successful implementation of strained silicon
with current standard semiconductor processes, with minimal impact on existing manufacturing lines.
Although they don't know what will successfully replace silicon
dioxide, manufacturers are specifying new machinery and otherwise making accommodations to handle likely alternatives in their production lines.

suffers an additional disadvantage when it comes to handling light.
During etching, the San Diego chemists project a black-and-white slide-in the case of these photos, George Washington's face from a dollar bill - onto the silicon
wafer through a lens that reduces the size of the image.
Using a charge-coupled device, the Stuttgart group showed that siloxene materials can emit a rainbow of colors, including porous silicon
's red and blue, a color not yet reported from porous silicon
and one crucial for creating color displays or signs, Brandt says.
Where bright light hits phosphorusdoped silicon
, red luminescence results; dim light leds to an orange glow; darkened parts do not glow at all.
SiGen has adopted its established and proven technologies for the solar industry, resulting in high performance, cost competitive single crystal silicon
for solar cells.
Davis discussed his group's achievements last week at the first International Conference on Amorphous and Grystalline Silicon
Carbide, hosted by Howard University in Washington, D.
Laboratories provides robust tools to support the C8051F52/3x MCU family, offering a fully integrated development environment that interfaces to the on-chip debug module via a USB to serial debug adapter.
What's more, because their techniquegives the researchers remarkable control over the small-scale structure of crystals, it will allow them to custom-tailor the properties of a great variety of materials in addition to silicon
, and to create crystals that have never before appeared in nature.
