Deep X-ray lithography and metal plating when coupled with a sacrificial layer, SLIGA, lends itself to the fabrication of very high aspect ratio metal structures which are mechanically stiff in the substrate direction and can be very flexible in the

Mechanical analysis and design of an improved class of differential pressure transducers is presented. Double-sided overload protection for a planar transducer is achieved with three-dimensional stops, produced with a process involving X-ray lithogra

A variant of deep X-ray lithography, the LIGA process, is described. The fundamental processing sequence has been augmented with a locally defined sacrificial polyimide layer. This requires alignment of the X-ray mask to the optically defined sacrifi

A bilevel photoresist system which uses optical processing only is presented. The photoresist for this work is poly(methyl methacrylate) or PMMA. It is sensitive to X-ray photons and deep ultraviolet radiation. It can be used for spin coating or can

The stability of the motion of thin elastic isotropic circular cylindrical shells subjected to suddenly developed temperatures is investigated. The excitation of particular unstable modes is identified from an evaluation of parameters in the equation

A closed-form solution is developed for stress waves in a solid resulting from volumetric energy deposition. The material is linear elastic and the geometry a plate or slab-like component. One dimensional waves perpendicular to the surface are consid
