For the past couple of decades the desire to add more complexity to a computer chip, while simultaneously reducing the cost per bit, has been accommodated by down-scaling. This approach has been extremely successful in the past, but like all good things it ...
The present invention is directed to a collimator that comprises grooves or channels in the submicrometer to micrometer range. The present invention is also related to uses of a collimator and collimator holder as described herein as well as apparatuses co ...
A generic method for the packaging of transducers at the foil level is proposed and was demonstrated on chemical gas sensors made on a plastic foil. The processing was based on the lamination of pre-patterned polymeric structures on the fabricated devices ...
Modern communication devices demand challenging specifications in terms of miniaturization, performance, power consumption and cost. Every new generation of radio frequency integrated circuits (RF-ICs) offer better functionality at reduced size, power cons ...
Today's consumer electronics based on a large variety of time-keeping and frequency reference applications is based on quartz-crystal oscillators, because of their excellent performances in terms of quality factor, thermal and frequency stability. However, ...
This paper reports on an inductor fabrication method capable to deliver high quality factor (Q) and high self-resonance frequency (SRF) devices using quartz insulating substrates and thick high-conductivity copper lines. Inductors are key devices in RF cir ...
Wireless communications are showing an explosive growth in emerging consumer and military applications of radiofrequency (RF), microwave, and millimeter-wave circuits and systems. Applications include wireless personal connectivity (Bluetooth), wireless lo ...
The present thesis deals with Micro-Electro-Mechanical Systems (MEMS) optical switches for telecommunication applications. The aim is to study new type of microsystems for guided-wave optical switching applications. Two projects have been investigated. The ...
Cantilever-based detection of ultrasmall forces is of great interest for several applications such as magnetic resonance force miscroscopy (MRFM) where an ultrahigh sensitive cantilever is used to detect magnetic resonance in small ensembles of electron or ...
A two-dimensional (2-D) array (4 by 8) of single-photon avalanche diodes integrated in an industrial complementary metal-oxide-semiconductor (CMOS) process is presented. Each pixel combines a photodiode biased above its breakdown voltage in the so-called G ...
