With wafer fabs running at near full capacity, it is a constant challenge to maintain high yields. Many different products are fabricated by the same equipment. So the sudden change in product yield, a yield excursion, can have a significant impact to many different products. Therefore, it is critical to detect an excursion as early as possible and fix the cause in order to minimize the impact. This...
In this work, a compact global system for mobile communications (GSM) bandpass filter is presented using integrated passive device technology on a GaAs substrate. An integrated passive device technology has been developed to obtain high performance, high integration, high yield, and low cost in RF/microwave communication system. We showed good RF performances with compact size and low cost compared...
We report sub-20 nm sacrificial nanochannels that enable stretching and translocating single DNA molecules. Sacrificial silicon nano-structures were etched with XeF2 to form nanochannels. Translocations of linearized DNA single molecules were imaged by fluorescence microscopy. Our method offers a manufacturable wafer-scale approach for CMOS-compatible bio-chip platform.
This paper presents the shaping of polydimethylsiloxane (PDMS) droplet on a flexible polyethylene (PE) membrane and the associated fabrication process of PDMS ellipsoidal micro-lens array (MLA). This design enlarges the viewing field and has better resolution than spherical MLA because the presented MLA is on a curved substrate and the ellipsoidal lens improves images. The PE membrane coated with...
The first successful demonstration of virus-structured, hierarchical electrodes for three-dimensional (3-D) Li-ion microbattery architectures is reported in this paper. The electrodes consist of electroplated gold micropillars and virus-structured nanocomposite materials with a TiO2 anode layer deposited on a nickel-coated viral template. Micropatterning increases the active electrode surface area...
