Power/Performance Bits: May 5


CMOS-compatible laser Researchers at Forschungszentrum Jülich, Center for Nanoscience and Nanotechnology (C2N), STMicroelectronics, and CEA-Leti Grenoble developed a CMOS-compatible laser for optical data transfer. Comprised of germanium and tin, the efficiency is comparable with conventional GaAs semiconductor lasers on Si. Optical communications provide much higher data rates, and are be... » read more

3.5D chip packaging In a recent paper, PacTech has described a vertical laser assisted bonding process for use in developing advanced 3.5D chip packages. Laser assisted bonding (LAB) is an interconnection technology used in IC packaging. It uses a laser as a thermal energy, which in turn connects a die bump and a substrate pad, according to Amkor, which is the original developer of LAB tech... » read more

Gummy bear chips The Technical University of Munich (TUM) and Forschungszentrum Jülich have developed a 3D inkjet printing technique to print electrodes on several soft substrates, including gummy bears. The main application is to develop a new class of sensor-based implants for life sciences. For this application, electrodes or microelectrode arrays (MEAs) are developed and printed on sof... » read more

Energy-harvesting fabric Researchers at the Georgia Institute of Technology and Chongqing University in China developed a fabric that can simultaneously harvest energy from both sunshine and motion. The fabric, just .32mm thick, was constructed using a commercial textile machine to weave together solar cells constructed from lightweight polymer fibers with fiber-based triboelectric nanoge... » read more
