Understanding the various mechanisms of nonlinear mode coupling in micro and nano resonators has become an imminent necessity for their successful implementation in practical applications. However, consistent, repeatable, and flexible experimental procedures to produce nonlinear mode coupling are lacking, and hence research into well-controlled experimental conditions is crucial. Here, we demon...

Wafer fabrication is a capital-intensive high-tech sector with highly complex manufacturing processes. Therefore, most of the fabs resort to production dispatching as a means to enhancing production efficiency. The commonly seen methods of production dispatching at the present time are devised to meet single performance indicators. Few methods take into account multiple, or even conflicting per...

300 mm semiconductor wafer fabrication facilities, like conventional semiconductor fabs, contain many different types of tools. In this paper we discuss a realistic way of representing cluster tools in a simulation model of the entire line. A more realistic representation of cluster tools results in greater accuracy in the output of the simulation model.

We introduce a new one-transistor nonvolatile memory, which benefits from the two seemingly unrelated memory mechanisms; namely ferroelectric (FE) polarization and nonvolatile charge injection. The hybrid memory demonstrates larger memory window and reduced depolarization field during retention compared to conventional FE-FETs. This summary discusses the working principle, device fabrication an...

The successful fabrication and experimental verification of a novel metamaterial based on flexible metallic helices is reported. The helices undergo compression under the influence of incident radiation, demonstrating a nonlinear chiral electromagnetic response, associated with the power-dependent change in the helix pitch. This design is promising for application to power-dependent polarizatio...

In situ one-pot rapid layer-by-layer assembly of polymeric films as an active layer of a photoactive device via alternation of reductive and oxidative electropolymerization has been demonstrated. This novel fabrication without moving or changing experimental gears would be a powerful strategy to develop automated layer-by-layer machines.

We describe the design, fabrication, and experimental demonstration of a circular Dammann grating element generating a point-spread function of two concentric rings with equal intensity. The element was fabricated using grayscale lithography, providing a smooth and accurate phase profile. As a result, we obtained high diffraction efficiency and good uniformity between the two rings.

We have designed and fabricated tunable gratings with period tunable to within fraction of a nanometer. We actuated the gratings by electrostatic and piezoelectric means, and demonstrated period changes of order 1 nm. Fabrication processes for the two versions are presented. Devices characterization and experimental results are given for respective devices. 2002 Elsevier Science Inc. All rights...
