High-Precision Thin Film Metal Liftoff Technique

This process can be used by industries that need to fabricate microelectronic devices and superconducting sensors. Goddard Space Flight Center, Greenbelt, Maryland The objective of this work was to develop a thin film metal liftoff process that would allow one to accurately pattern two-micron-wide (or wider) features. The goal of this innovation was to pattern thin metal films on silicon substrates. The thin metal films can be deposited using physical vapor deposition techniques. The metallic films to be lifted off were deposited via DC magnetron sputtering, in which the mean free path of the metal atoms to be deposited is on the order of one micron. Thus, the deposited metal could conformally coat structures to fill in gaps that were greater than approximately one micron tall.

Process for 3D Printer Filament Fabrication

Marshall Space Flight Center, Alabama Conventional filament extrusion processes are unsuitable for recycling materials on the International Space Station due to requirements for continuous monitoring and tuning, as well as poor filament dimensional control. The Positrusion process recycles scrap or waste thermoplastics into filament for 3D fused filament fabrication (FFF) printers.

Products of Tomorrow: December 2015

The technologies NASA develops don’t just blast off into space. They also improve our lives here on Earth. Life-saving search-and-rescue tools, implantable medical devices, advances in commercial aircraft safety, increased accuracy in weather forecasting, and the miniature cameras in our cellphones are just some of the examples of NASA-developed technology used in products today.

Product of the Month: December 2015

Keysight Technologies, Santa Rosa, CA, introduced series E36100 compact DC power supplies that offer LAN and USB interfaces and reliable power for testing and validating designs. Five models feature up to 100 V or 5 A output. Design and validation engineers can use the supplies to power devices under test (DUTs) during manual tests or automated sequences. The devices’ compact form factor (2U, ¼-rack) enables use on a bench or in a rack, and standard LAN (LXI Core) and USB interfaces connect the power supplies to a computer. An intuitive on-screen menu system enables users to perform manual tasks quickly, and overvoltage and overcurrent detection protects DUTs. Each of the five models comes standard with measurement capability for very small currents, a high-contrast OLED display enabling users to view the screen from anywhere, low noise power, overvoltage and overcurrent load protection, front and rear output terminals, and USB control.

Multi-Screen Imaging

The Transcoder Gateway from Pleora Technologies (Kanata, ON, Canada) transmits GigE Vision and USB3 Vision video to any playback device, including tablets and smartphones. While preserving the high-quality video required for processing and analysis, the image feed is converted into the H.264 compression format and transmitted over a wired or wireless connection using the realtime streaming protocol (RTSP) to a playback device. The image feed can also be saved as IEEE 1588 time-stamped video to USBattached storage media, and output with administrator-specific overlays via an HDMI connection to high-definition displays.
