Due-date performance is one of the most important production indexes for success utilized by wafer fabrication factories. Traditionally, the industry sets a specific due-date tightness level and a dispatching rule based on the total processing time, the production capacity, pre-defined order release criteria and historical data, to ensure deliveries are made on-time. However, such policies typi...

With today’s keen competition, semiconductor market has changed from producer-oriented to customer-oriented. To be successful, companies need to consider both customer satisfaction in demand and the ultimate profit goal of companies. Semiconductor fabricators today must face an environment with multi-product types and multi-priority orders. Since semiconductor fabrication has a very complicated...

In the process of decision-making, sometimes analysts are given a sub-set of criteria for which statistical data are available from experiments, whereas for some other criteria, only qualitative judgments can be made. In such situations, it is important to consider the weights of experimental criteria along with the decision maker’s qualitative weights. Furthermore, in complex decision scenario...

Emulsions formed by mixing reactant streams inside microdroplets are efficient microscale reactors for the synthesis of nano/microparticles/crystals due to small quantities reagents confined within each droplet and separation contents from reactor walls. In this work, size-tunable gold nanoparticles (AuNPs) emulsion droplets generated in a three-phase glass capillary microfluidic device was inv...

Fabrication and experimental characterization of a broadband quarter-wave plate, which is based on two-dimensional and binary silicon high-contrast gratings, are reported. The quarter-wave plate feature is achieved by the utilization of a regime, in which the proposed grating structure exhibits nearly total and approximately equal transmission of transverse electric and transverse magnetic wave...

We report on the first experimental evidence of guided resonances (GRs) in photonic crystal slabs based on aperiodically-ordered supercells. Using the Amman-Beenker (quasiperiodic, 8-fold symmetric) tiling geometry, we present our study on the fabrication, experimental characterization, and full-wave numerical simulation of two representative structures (with different filling parameters) opera...

Robustness is a limiting factor in experimental development of multifingered robot hands: the expense and fragility of these hands precludes casual experimentation, restricting the type of experimental tasks that can be reasonably attempted and slowing implementation due to the need for careful validation of programs. In this paper, we describe the design, fabrication, and evaluation of a novel...

The minimum requirements of the parameters such as the amplitude and phase distribution errors on an antenna aperture are obtained by using the statistical simulation method for 73 elements. From the results, appropriate beamformer method is selected. Instead of the full system, this paper presents the design and fabrication of the experimental model with 4 channel receivers and four linearly a...

This paper concerns optically driven quantum logic devices based on semiconductor quantum dots. It provides a brief review of recent theoretical and experimental progress towards building such devices and a description of a possible direction of further research. We consider both the exciton and the electron spin as a potential qubit. Quantum dot fabrication and single dot spectroscopy studies ...
