Manufacturing Bits: Jan. 6


Vertical SiC chips for electric cars Silicon carbide (SiC) is a promising material for power electronics. The material has a high breakdown voltage, high operating temperatures and a superior thermal conductivity. At the recent 2014 IEEE International Electron Devices Meeting (IEDM) in San Francisco, Toyota, the National Institute of Advanced Industrial Science and Technology (AIST) and the... » read more

Mechanical switches For years, the industry has been talking about the use of advanced mechanical switches in low-power applications. In theory, mechanical switches have zero off-state leakages, abrupt ON/OFF switching capabilities and small voltage swings. Mechanical switches could overcome the energy efficiency limit of CMOS. In fact, mechanical switches could replace CMOS in some applica... » read more

Whispering sensors Inspired by a whispering technology from a famous cathedral, Washington University in St. Louis and Tsinghua University in China have developed a new sensor that can detect and count nanoparticles down to 10nm and perhaps below. Researchers have devised a Raman microlaser sensor in a silicon dioxide chip. The microsensor is called a whispering gallery mode resonator (WGMR... » read more

Skateboarding on 2D materials Two-dimensional materials are gaining steam in the R&D labs. The 2D materials include graphene, boron nitride (BN) and the transition-metal dichalcogenides (TMDs). These materials are attractive candidates for futuristic field-effect transistors (FETs). But researchers must gain more insight into these materials in order to understand their properties. For ... » read more

Silky e-beam lithography Tufts University has put a soft and silky spin on direct-write electron-beam lithography. Researchers used common silk as the resist material, enabling the production of photonic lattices, quantum dots and other structures. This approach is a green alternative to traditional and toxic resists. The silk-based resist is developed using a water-based process. It starts... » read more
