Conventional time consuming methodology and idealistic stress conditions are no longer satisfactory under fierce competition between advanced technology development approaches. In this paper, the effectiveness of test arrays with simple built-in self-test (BIST) design in FinFET high-k/metal gate (HK/MG) technology have been demonstrated through three experiments performed early in the process development...
Increasingly, professionals seek knowledge from online communities to resolve problems that they encounter in the workplace. However, the quality and reliability of online content are still a concern. Previous research suggests that user involvement in sorting out online content is likely to be an effective means to ease some of the concern. Nonetheless, our understanding of factors that influence...
We propose multihoming, the token synchronization, and the packet selection in FL-net to achieve fault tolerance. Multihoming assigns two IPs on two interfaces which reach two disjoint paths so that 1 + 1 packets in FL-net for the 1 + 1 protection architecture are supported. However, based on the architecture, a problem called delay mismatch makes FL-net nondeterministic because of collisions. To...
Wafer-level integration of GaAs enhancement-mode pHEMT, depletion-mode pHEMT and HBT (H2W is the code name at WIN) is a very appealing technology, which offers a number of significant advantages over conventional device technologies. In this paper, we report the development and mass-production status of the H2W at WIN Semiconductors. In addition to the device fabrication, we also demonstrate a single-chip...
Inter-firm R&D collaboration is valuable for companies when it helps them to gain complementary intellectual resources, access to diverse markets, share product development's cost, shorten the time to market of new products, and avoiding redundant expenditures. This kind of collaboration could be considered as a good way responding to the modern business world today which is dynamic, complex,...
We proposed and experimentally demonstrated two approaches to tunable photonic Ultra-wideband (UWB) signal generation based on nonlinear dynamics of the semiconductor laser. 1) UWB pulse generation based on chaotic dynamic of the optical feedback laser diode; 2) UWB pulse generation based on period-one oscillation of the optical injected laser diode. Both of the methods are convenient to adjust and...
We numerically and experimentally demonstrate a technique for performing all optical wavelength conversion with simultaneous clock division based on the period-one oscillation and cross-gain modulation effect in an optically injected semiconductor laser. Through the numerically simulation, the results that 18 GHz divided optical clock with wavelength down conversion of 5nm can be obtained from 2 ×...
GaAs based hetero-junction bipolar transistors (HBTs) offer high speed and good device matching characteristics that are attractive for many high-speed circuits. However, thermal behaviors with multi-fingers can significantly affect HBTs performance. In this paper, three dimensional (3-D) finite-element modeling (FEM) approaches are built up to analyze the maximum temperature region and temperature...
This paper describes an embedded workflow framework (EMWF) that enables flexible personal and home automation and assistive devices and service and social robots (collectively referred to as SISARL) to be built on workflow architecture The process definition language supported by EMWF is called SISARL-XPDL. It consists of a subset of the WfMC standard XML Process Definition Language (XPDL) 2.0, together...
In this work a linear field model is adopted to study the reliability of capacitors which are manufacturing in Win's production line. Two testing techniques, a constant voltage and a ramped voltage testing modes, are compared in order to examine in various sizes and shapes which testing techniques may give us a better way to predict the capacitor lifetime. It seems to us that the constant voltage...
GaN Schottky barrier photodetectors (PDs) separately prepared with a conventional single low-temperature (LT) GaN buffer layer and a multi-MgN/GaN buffer layer were both fabricated. It was found that we could reduce threading dislocation (TD) density and thus improve crystal quality of the GaN PDs by using the multi-MgN/GaN buffer layer. With a 2 V reverse bias, it was found that the reverse leakage...
Bit-planes for digital gray images have been used in many applications for special feature extraction. This paper presents analysis of single and combined bit-plane performance for face recognition. Novel approach of using bit-plane as input to Feedforward Neural Network is used. Comparison is done to analyze recognition rate of using single and combined bit-planes. Every single pixel in an 8-bits...
Although the automotive industry is relatively efficient in managing the production line, mass customization remains a major challenge. The difficulty lies in the establishment of channels to support customer feedback and interaction in directing the planning and design new products. There is thus a big gap between user requirements and product features. We explore the development of a platform for...
MHEMT technology using metamorphic buffer layers growing on GaAs substrate can overcome InP substrate issues. Several researchers have demonstrated reliable MHEMT devices, mainly with the drain bias at 1 V. This work, however, demonstrated for the first time MHEMT devices operated at drain voltage greater than 3 V for the amplifier application. We have demonstrated the power MHEMT at 3.5V drain bias...
A new and precise dual logarithm model are derived to estimate WCDMA downlink pole capacity in the local multipath propagation channel and verified with measurements from several live Node B sites. Model estimations show excellent consistence with measured data. As well, cell-breathing phenomenon has been detected. In estimating the Downlink pole capacity of WCDMA radio network, we propose a new algorithm...
There are two parameters ought to be evaluated in estimating downlink pole capacity of the WCDMA radio network. One is the downlink interference ratio, which can be precisely calculated with the link quality equation for all covered cells. Another is the downlink orthogonality factor, which is usually unknown for different multipath propagation channels in various clutter environments. When radio...
Metal-insulator-metal (MIM) capacitors are deposited at low temperatures. The dielectrics used for MIM capacitors are amorphous and always contain a certain amount of extrinsic defects. In this paper, the reliability of extrinsic defects in SiNx MIM capacitors as part of a GaAs high voltage (HV) FET process was assessed. It was shown in this paper that the number of extrinsic defects depends on the...
The main objective of this research is to develop an image matching prototype that can retrieve images based on the geometry feature representation of a complete object or a partial object. Consequently, a shape decomposition method is introduced to preserve the shape feature for the remaining portion of a partial object and to simplify the shape complexity by breaking down into segments.
The die edge-seals and circuit under fad (CUF) are structurally optimized through 3D finite element analysis (FEA). Die edge-seals having the mechanically reinforced structure units are demonstrated essential. It is also shown that FEA help extract useful structural design concepts for CUP. The Poisson effects leading to a dual-ring-shaped high stress distribution area are confirmed to be detrimental...
