This work introduced a novelty MEMS pyroelectric infrared detector based on LiTaO3 (LT) crystal with high absorptivity amorphous carbon film layer. The LT crystal is thined and polished to 100um thickness and double mentaled for electical connection which will be suspened upon rectangle cave of silicon substrate with mental ring. Amorphous carbon(a-C) could be produced by magnetron sputtering on the...
Microstructured semiconductor neutron detectors (MSNDs) represent a low-cost, high-efficiency means of solid-state thermal neutron detection. Trenches are etched into a pn-junction diode and backfilled with nano-sized 6LiF neutron converting material. Neutrons absorbed within the conversion material produce charged particle reaction products that interact within the semiconductor substrate and generate...
This paper reports the first implementation of a highly sensitive micro discharge photoionization detector (μDPID) in a silicon-glass architecture and its monolithic integration with a high performance micro separation column. The new detector requires a two-mask fabrication process, is universal, non-destructive, low power (<2.5mW), and insensitive to flow and temperature variations. It has yielded...
The General Antiparticle Spectrometer (GAPS) experiment is an indirect dark matter search that aims to detect low-energy antideuterons resulting from dark matter annihilations and decays in the Galactic halo. Layers of semiconducting lithium-drifted silicon (Si(Li)) tracking detectors are essential to the success of the GAPS detection and background rejection scheme, requiring ∼22.5 square meters...
Presented is a method to build silicon multi-pixel x-ray detectors for use on the Argonne National Laboratory's Advanced Photon Source x-ray synchrotron. These detectors are PIN diodes constructed using heavily doped oxide sources. The construction method chosen helps reduce the background leakage current and allows for a minimum of process steps. We discuss test results of the characterization of...
For precise treatment purposes in hadrontherapy, the particle beam has to be monitored in real time without being degraded. For the first time, silicon strip detectors have been fabricated over an area as large as 4.5cm ?? 4.5cm with ultra low thickness of 20 microns in order to reduce the beam scattering. In this work, we briefly describe the fabrication process and characterize this novel detector...
We demonstrate self-aligned fabrication of etched silicon fins in metallic slits and show that this structure supports both dielectric and plasmonic resonances and photodetection that can be tuned by varying the width of the fin
We present DWDM nanophotonics architectures based on microring resonator modulators and detectors. We focus on two implementations: an on chip interconnect for multicore processor (Corona) and a network that uses high-radix switches (HyperX). Based on the requirements of these applications we discuss the key constraints on the photonic circuits' devices and fabrication techniques as well as strategies...
Wafer-scaled cost-effective technique for subwavelength structured (SWS) surface by means of anodic porous alumina masks directly formed on SiO2/Si substrates is demonstrated. Combined with ion beam etching and induced coupled plasma etching, SWS surface with a period of 100nm and a height of 200-300nm was achieved on 2 inch polished single crystalline Si wafer. A lower reflectivity below 6% was observed...
We present the design, fabrication, and operation of the first monolithic gas chromatography (GC) separation column and detector. The monolithic integration of a high sensitivity detector with a separation column has many potential advantages over the discrete components of a traditional chromatography system. In high-speed GC systems, component interconnections can cause crucial errors which increase...
A uncooled amorphous silicon (alpha-Si) infrared (IR) detector with novel thermal isolation method has been fabricated and characterized. The unique sandwich IR absorption structure based on polyimide (PI) and bottom metal reflective layer is presented. The fabrication process of the IR detectors is described. The absorption characteristics of the IR detectors have been investigated. The responsivity...
A hybrid approach to fabrication of single tunable infrared detectors for sensing applications is presented. In this approach the detector and IR Fabry-Perot tunable filter are fabricated separately and then bonded together using a flip-chip technique. This approach allows for less stringent processing conditions for both, detector and filter, resulting in the following advantages: (1) the maximum...
