We report a mask-free technique for the local synthesis of ZnO nanowires (NWs) on polysilicon nanobelts and polysilicon NW devices. First, we used localized joule heating to generate a poly(methyl methacrylate) (PMMA) nanotemplate, allowing the rapid and self-aligned ablation of PMMA within a short period of time (ca. 5 μs). Next, we used ion-beam sputtering to prepare an ultrathin Au film and ...

We have investigated the feasibility of multimode polysilicon waveguides to demonstrate the suitability of polysilicon as a candidate for multilayer photonic applications. Solid Phase Crystallization (SPC) with a maximum temperature of 1000°C is used to create polysilicon on thermally grown SiO2. We then measure the propagation losses for various waveguide widths on both polysilicon ...

The paper describes the performance analysis, structural design and fabrication of piezoresistive pressure sensor using simulation technique. A polysilicon double nano-wire piezoresistor was fabricated by means of RIE (reactive ion etching). The polysilicon double nanowire pressure sensor has 100x100nm cross section area and has a thickness about 10nm. Finite element method (FEM) is adopted to ...

We have developed a process of growing ultrathin oxide on polysilicon layer by using Electron Cyclotron Resonance (ECR) N2O plasma. Sub-4 nm thick polyoxide on n+ and p+ polysilicon layer were grown and characterized. The oxides have relatively large breakdown voltage, small electron trapping and QBD up to 7 C/ for polyoxide on p+ cm2 polysilicon and up to 5 C/ for polyoxide on n+ polysilicon u...

ESD protection in RF integrated circuits has several considerations: low parasitic capacitance, constant input capacitance, and insensitive to substrate coupling noise. In this paper, a new ESD protection design with polysilicon diodes for RF IC applications is proposed and characterized. The proposed polysilicon diode is constructed by polysilicon layer in a general CMOS process with a central...

A comprehensive study is made of the behavior and effects of fluorine in n-polysilicon layers. The polysilicon is deposited in a conventional low pressure chemical vapor deposition furnace on ~100! silicon wafers, implanted with 1310 cm F and 1310 cm As and annealed at 850, 950, 1015, and 1065 °C. Sheet resistance, transmission electron microscopy ~TEM!, and secondary ion mass spectroscopy are ...
