... discusses molecular-based models and their relation to the continuum models previously considered. The most fundamental of the molecular models is a deterministic one. The motion of the molecules is ... containing 34 20 0- µ m- wide × 10 0- µ m- deep channels machined into the 20 0- µ m- thick stainless steel foils by the process of direct, high-precisio...

... R 111 the etch rate in nm/min and R v the groove widening, also in nm/min. The V-groove widening experiment then results in a R 111 of 2. 55 ± 0.15 nm/min. In practice, this etch rate implies a mask underetching ... R 111 the etch rate in nm/min and R v the groove widening, also in nm/min.

... fundamental problems that arise from the small dimension of the channels must be solved. Most of these problems originate from the large curvature of the interface between two phases in these small ... control. This topic is particularly important in microelectromechanical systems (MEMS) applications for two reasons. First, as electromechanical systems, MEMS devices often must be co...
