Low cost planar ferroelectric thick film varactors based on Barium Strontium Titanate (BST) are realized and their nonlinear behavior with varying DC bias is investigated. A model for the capacitance tunability is utilized for nonlinear simulations and compared to measurements. The model based on static measurement of the varactor's capacity is extended by the results from measurements with pulsed...
Investigation of computational profiling of laser processing on glass substrate was carried out to provide numerical solutions to the selection of the laser parameters for microchannel fabrication. Polynomial equations were derived from DadtFit programming to classify and map the randomly scattered paired-data into four different regions, which indicated the four different phenomena induced in laser...
In semiconductor manufacturing processes, mixed-products are usually fabricated on the same set of process tool with different recipes. Run-to-run controllers which based on the exponential weighted moving average (EWMA) statistic are probably the most frequently used in industry for the quality control of certain semiconductor manufacturing process steps. However, for mixed-product drifting process,...
