We report the detection of p53 antibody as a biomarker for early-stage cancer diagnosis using a microcantilever biosensor with piezoresistive readout. The accumulation of p53 antibody in human sera is found strongly involved in a variety of human cancers, thus simple and fast detection of the level of p53 antibody is of importance in clinical application.(More)
This paper presents the design, fabrication, and characterization of a piezoelectric micromachined ultrasonic transducer (pMUT) operating in d<sub>33</sub> mode. A piezoelectric PZT thin film is polarized along the in-plane direction using top square interdigital electrodes (IDEs), and the in-plane polarization and IDEs enable the pMUT to operate in(More)
A novel Fuzzy Genetic Algorithm based RF IC optimal design approach is proposed in this paper. RF design difficulty is alleviated because of Genetic Algorithm, which is capable of fast global searching. Fuzzy Logic Algorithm is introduced to solve problems in generating a proper cost function from multiple objectives. Key issues have been identified as(More)
Due to complex hardware architecture and heavy computation, it is difficult to perform modular multiplications over large integers. In this paper, we propose a low-latency scalable modular multiplier for multi-precision modular multiplications. Unlike popular scalable architectures by Montgomery algorithm, the classic modular multiplication A &#x00B7; B mod(More)
Resistance random access memory devices based on nanoscale diamondlike carbon (DLC) films are demonstrated. The devices exhibit excellent memory performances such as high on/off-resistance ratio (&gt;; 300), high switching speed ( &lt;; 50 ns), low operation voltage ( &lt;; 1.2 V), low switching power consumption ( &lt;; 16 &#x03BC;W), nondestructive(More)
This paper presents a method for measuring the complex permittivity of Ba/sub 0.5/Sr/sub 0.5/TiO/sub 3/ (BST) ferroelectric thin films on a four-layered substrate at frequencies from 50 MHz to 26.5 GHz. Coplanar waveguide (CPW) lines are employed to measure the permittivity at high frequencies, whereas at low frequencies interdigital capacitors (IDCs) are(More)
This paper presents on a novel chip-to-wafer (C2W) three-dimensional (3D) integration technology with well-controlled template alignment and wafer-level bonding, enabling precise alignment, few thermal cycles and high throughput of 3D system fabrication. The key processes are investigated and discussed in detail, including chip edge definition, template(More)
The ever-growing applications of lead zirconate titanate (PZT) thin films to sensing devices have given birth to a variety of microsensors. This paper presents the design and theoretical analysis of a PZT-based micro acoustic sensor that uses interdigital electrodes (IDE) and in-plane polarization (IPP) instead of commonly used parallel plate-electrodes(More)
