A variety of physical mechanisms have been exploited to capture electronic images of a human fingerprint, including optical, capacitive, pressure, and acoustic mechanisms. Compared to other technologies, ultrasonic fingerprint sensors have two major advantages (1) they are insensitive to contamination and moisture on the finger (2) they have the ability to measure images at multiple depths hundreds of microns from the sensor surface. With the maturity of the thin film piezoelectric materials technology and MEMS-CMOS eutectic wafer-bonding process, piezoelectric micromachined...

Large, Ordered 3D Nanocup Arrays for Plasmonic Applications

2010

A large, ordered nanocup array was fabricated and optically characterized. A novel fabrication method that combined Nanoimprint lithography (NIL), soft lithography, and shadow evaporation was designed to create asymmetric nanoparticles in a large (0.5cm x 1cm) array with subwavelength features. Although this fabrication procedure can be used to create many different types of asymmetric nanostructures that are useful in various plasmonic applications, here we fabricated a periodic nanocup array...

BPN551: Large, Ordered 3D Nanocup Arrays for Plasmonic Applications

Joanne Lo
2010

Here we present a novel method for fabricating large, ordered arrays of 3D nanocups for plasmonic applications. Previously, it has been demonstrated that nanocups provide a unique method for bending scattered light by creating “magnetic plasmon” responses in optical frequencies. However, creating large, ordered arrays of nanocups has remained a significant challenge. We constructed a large (0.5 cm X 1.0 cm), ordered array of nanocups via nanoimprint lithography (NIL), soft lithography, and shadow evaporation. This methodology enables high control over the shapes and optical...
