Aspect-Ratio-Dependent Copper Electrodeposition Technique for Very High Aspect-Ratio Through-Hole Plating

Copper electrodeposition in high-aspect-ratio through-holes micromachined by deep reactive ion etching is one of the most essential processes for fabricating through-wafer interconnects, which will be used in developing future generation high-speed, compact 3D microelectronic devices. Although copper electrodeposition is a well-established process, completely void-free electroplating in very de...

A Thermoacoustic Model for High Aspect Ratio Nanostructures

In this paper, we have developed a new thermoacoustic model for predicting the resonance frequency and quality factors of one-dimensional (1D) nanoresonators. Considering a nanoresonator as a fix-free Bernoulli-Euler cantilever, an analytical model has been developed to show the influence of material and geometrical properties of 1D nanoresonators on their mechanical response without any dampin...

Approaches to High Aspect Ratio Triangulations

In aerospace computational uid dynamics calculations, high aspect ratio, or stretched, triangulations are often used to adequately resolve the features of a viscous ow around bodies. In this paper, we explore alternatives to the Delaunay triangulation which can be used to generate high aspect ratio triangulations of point sets. The method is based on a variation of the lifting map concept which...

High-aspect-ratio bulk micromachining of titanium.

Recent process developments have permitted the highly anisotropic bulk micromachining of titanium microelectromechanical systems (MEMS). By using the metal anisotropic reactive ion etching with oxidation (MARIO) process, arbitrarily high-aspect-ratio structures with straight sidewalls and micrometre-scale features have been bulk micromachined into titanium substrates of various thicknesses, ran...
