High-aspect ratio through-silicon vias for the integration of microfluidic cooling with 3D microsystems

High Aspect Ratio Si Etching in STS2

Deep reactive ion etching (DRIE) is one of the most important etching techniques because it is independent of crystal orientation and does not require any wet process. DRIE can be applied for many applications. For examples, this technique can be used to fabricate MEMS devices (e.g. accelerometers, scanners, etc.), microfluidic devices, electrical through wafer interconnects, and so on. In many...

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...

Nonlinear Aeroelastic Analysis of Aircraft with High-aspect-ratio Wings

The paper describes a formulation for aeroelastic analysis of aircraft with high-aspect-ratio wings. The analysis is a combination of a geometrically-exact mixed formulation for dynamics of moving beams and finite-state unsteady aerodynamics with the ability to model dynamic stall. The analysis also takes into account gravitational forces, propulsive forces and rigidbody dynamics. The code has ...
