Method for Providing Semiconductors Having Self-Aligned Ion Implant

Refined self-aligned ion implantation for improved SiC high-temperature transistors. John H. Glenn Research Center, Cleveland, Ohio This is a modification to technology for realizing durable and stable electrical functionality of high-temperature transistors. This modification is believed crucial to experimental implementation of SiC junction field effect transistors that electrically operated continuously at 500 °C for over 10,000 hours in an air ambient with less than 10% change in operational transistor parameters.

Femtosecond Laser Processing of Metal and Plastics

Precision machining can be achieved with no thermal affects and minimal post-processing. Amada Miyachi America, Monrovia, California and Jenoptik, Jena, Germany While precise and fast, the down side to cutting with microsecond (ms) fiber lasers has been that the parts require a number of post-processing operations after they are cut, which add significantly to part cost, and can also damage mechanically delicate parts.

NASA Spinoff: NASA’s UV Radiation Research Keeps Sun Worshipers Safe

Studying radiation effects on spacecraft led to a personal Sun exposure monitor. To understand the Sun’s impacts on Earth, NASA initiated the Living with a Star program in 2001, and began developing a key research satellite: the Solar Dynamics Observatory (SDO). One of the instruments created for the SDO was the Extreme Ultraviolet Variability Experiment (EVE), tasked with measuring extreme ultraviolet (UV) radiation, which plays a key role in atmospheric heating and satellite drag. In 2005, Goddard Space Flight Center scientist Shahid Aslam joined other researchers in developing EVE.

Product of the Month: May 2015

Sensirion, Westlake Village, CA, introduced a gas sensor that, according to the company, is the first in the world to be based on multi-pixel technology. This allows the sensor to perceive its surroundings using various receptors that, with the help of intelligent algorithms and pattern recognition, are able to detect the type and concentration of gases. The single sensor is capable of detecting and distinguishing between different gases. It measures 2.45 × 2.45 × 0.75 mm, and can be integrated anywhere. Using the sensor, mobile devices will be able to sense their surroundings in order to measure indoor air quality, determine the alcohol content of a person’s breath, or recognize smells.

3D-Printed Functional Antenna Arrays Operate on Exterior of COSMIC-2 Satellites

FDM® (Fused Deposition Modeling™) technology and ULTEM 9085 thermoplastic Stratasys Direct Manufacturing (RedEye, Solid Concepts, and Harvest Technologies) Eden Prairie, MN 866-882-6934 www.redeyeondemand.com In 2006, a satellite mission called the Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC-1) was put into orbit. The purpose of the instrument was to collect global ionospheric and atmospheric data of temperature, moisture, and pressure, including hard-to-sample areas such as above oceans and polar regions. The project was led by the University Corporation for Atmospheric Research (UCAR), a consortium of more than 70 research universities in the US, and Meteorological Society of the Republic of China (Taiwan). Since its inception, the COSMIC-1 project has contributed to a wide range of scientific investigations and improvements in weather forecasting.
