A 330,000 gate field programmable gate array (FPGA) VS12C fabricated on 0.2μm full-depletion silicon-on-insulator (FD SOI) process is presented and the test results indicate this chip has the lower power and higher tolerance to radiation compared with Xilinx radiation-hardened XQVR300 chip implemented on 0.22μm epitaxial silicon. This paper demonstrates the benefit of the FD SOI technology on low...
This paper presents the use of Terahertz (THz) SPR near-field sensor based on array of sub-wavelength metallic holes and Bull's eye structure to characterize materials such as PMMA and those used in organic light emitting diode (OLED). The measurement results confirmed the theoretical SPR frequencies for metal-silicon mode and demonstrate a shift to 0.9211 THz from 0.9375 THz due to 2 µm of PMMA layer...
We experimentally demonstrate an accurate post-fabrication trimming technique for the correction of the optical phase of silicon photonic devices using a single fabrication step. Using this technique, we reduce the random resonance wavelength variation of ultra-compact silicon resonators by a factor of 6 to below 50 pm.
We report the fabrication of a mechanically-flexible 16×16 array of thin-film, micron-size LEDs emitting at 480 nm. Devices were transfer-printed onto a mechanically-flexible ITO backplane using a modified, high-precision (placement accuracy ±25 nm) assembly system.
We present a design and characterization method for a scalable ultra-wide voltage range (UWVR) SRAM bitcell array, targeting a minimum voltage prediction, high yield and Si-CAD correlation within 5%. The experimental validation is first performed in bulk CMOS 65nm, then confirmed in 28nm FDSOI. Over 10x energy gain is achieved from 1.2V down to 0.35V range while measuring high speed at nominal voltage.
InGaN micro-light emitting diodes on Si substrates have been fabricated and characterized. Their abilities for micro-display, high modulation bandwidth of 270 MHz and data transmission rate of up to 400 Mbit/s have been demonstrated.
We demonstrate an efficient guided-mode resonant color filter array. It consists of a thin subwavelength silicon nitride grating and a homogeneous silicon nitride waveguide on a glass substrate. The fabricated device exhibits high experimental efficiencies.
A fabrication process for a thermo-diode microbolometer array is presented. The process is based on a sintered porous silicon (sPS) technique adopted from Chipfilm™ technology to enable vertical thermal insulation of the pixels. In addition, the process offers the possibility to have more than one diode per pixel connected in series. It is demonstrated that this boosts the temperature sensitivity...
MOSFETs and Tunnel-FETs (TFETs) based on arrays of nanowires (NWs) with 10 × 10 nm2 cross-section have been fabricated with strained silicon on insulator substrates. MOSFET devices show near ideal subthreshold slope close to 60 mV/dec proving excellent channel control achieved by high-klmetal gate stack. As expected fundamental differences between MOSFETs and TFETs in current-voltage characteristics...
Based on experimental results and a dedicated model, the impact of various technological parameters on the performance of a frequency addressed NEMS arrays sensor is investigated for mass sensing application. It is shown that the number of NEMS resonators that can be addressed in parallel is limited by critical dimensions fluctuations, the quality factor of the NEMS and their resonance frequencies.
In this project, we employ a microcantilever based mechanical transduction DNA detection approach. We believe that the method to traduce and amplify signal has much wider implications for many binding assays in chemistry and biology, such as that in immunoassay. The core idea is to measure the bending and the stress of a microcantilever induced by DNA hybridization. A porous polysilicon cantilever...
Large-scale optical phased arrays containing up to 64×64 nanoantennas are demonstrated on silicon photonic platform, representing the largest scale demonstrated to date. Active phase tuning is also realized for dynamic pattern generation.
In manufacturing, the dielectric constant of High-speed PCB's dielectric material is difficult to control in a certain value. So the dielectric constant is uncontrollable factor. The paper carries out a comprehensive study of the impacts of the different dielectric constant in various differential-via design parameters on signal integrity (SI) using a full-wave electromagnetic simulator (HFSS) and...

The target of this research is to study the influence of TSV array pattern on signal transmission characteristic and to give a guide for the design of package level interconnect using TSV arrays. The simulation results...
ART guidelines of World Health Organization recommend a series of tests for HIV diagnostics (HIV antibody test, CD4 cell count and HIV viral load count). There are several modern technologies that are available to ensure reliable HIV diagnosis employing various principles. However, there is a need for point-of-care system that will eliminate the requirement of the patient to visit a hospital for initial...
An novel on-chip synthesis technique for nanochannel arrays inside microfluidic channels is reported. The microfluidic channels are constructed with etched silicon trenches and a polydimethylsiloxane (PDMS) slab. These silicon microchannels provide a confined environment for highly oriented nanostructure synthesis. Triblock copolymer (SBA-15) is self-assembled inside the microchannel array as template...
Ultrasonic Inspection is effective for inspecting ceramic materials because ultrasonic waves are easily propagated in general ceramic materials. Aperture synthesis cannot derive high quality image of internal defects in ceramic sample because the acoustic velocity of ceramic materials is very high, compared to metal samples. In this study, internal defect images were reconstructed by Truncated Singular...
We describe the analysis of a slotted array antenna that is fed from a travelling wave structure. The antenna consists of an array of slots in the surface of the waveguide. The slots are fed by a travelling wave and the degree of slot coupling can be chosen by the slot and coupling-hole dimensions. We obtain expressions for calculating this coupling and the radiation from the array. The analysis is...

Electric utility companies curb their system peak power demand through numerous Demand Response (DR) programs, such as the Time-Of-Use (TOU) rates where the cost of energy is typically much higher during the peak period and lower for the rest of the time relative to the standard flat rate. Meanwhile, a vertically installed West-facing bifacial PV array is expected to provide an advantage over a conventional...
