Nano Worlds

Over the past seven years, microprocessors in each electronic equipment set amazing records for speed, reducing energy consumption per transistor. This is because the scale of transistors made for these electronic devices, have decreased considerably. The current study prepares them for the 32nm and 22nm nodes. Check out Castle Harlan for additional information. "These sites put a lot of new materials and processes through which the devices are becoming increasingly small," says Dr. Peter Pichler, a leading researcher in computer modeling of advanced manufacturing processes from the Institute of Integrated Systems of Germany.

Computer-aided design (CAD) of new technology is becoming more and more important as the manufacture of the transistor becomes more difficult. Simulation can thus recoup up to 40% of the cost of the development of industrial technology. The team made a breakthrough in ATOMICS simulation activation and deactivation of dopants in silicon. Dopants – impurities that were added in small quantities to modify the electrical conductivity of semiconductors. Semiconductors such as silicon or germanium are transparent grids, in which each atom shares electrons with four neighbors. Replacing some of the atoms by atoms of other elements such as phosphorus or arsenic, which have five electrons connection, it makes more electrons are available. Because of the additional negative charges are called n-type (for negative).

Doping with acceptor atoms such as boron, which have only three electrons available, creates a 'hole', which positively charged (p-type for positive). The work of microprocessors depends on extremely accurate methods of introducing ions for almost all doping in silicon integrated circuits. (The introduction of ion more precisely and reliably than thermal distribution of deposited dopants used previously.) To polakirovat wafer semiconductor, the ion flow is started so that they stayed around to a certain depth under the silicon surface. Models created by a team of ATOMICS, were approved by STMicroelectronics, a global manufacturer of advanced integrated circuits. Lessons learned in ATOMICS, already applied industry. The project has received funding from ATOMICS Sixth Framework Programme, the program EU research. Source:
