This publication presents lithography results for 3D wafer-level system integration applications using a reticle free maskless VPG+ 400 from Heidelberg Instruments. The focus is on high density Cu redistribution layer (RDL) formation with <2µm L/S used in polymer RDL stacks, overlay accuracy determination better than ±150nm and hybrid bond interconnect 2µm interconnects, all processed 300mm ...

The CorInnova cardiac compression device (CorInnova, Inc., Houston, TX, USA) is designed to provide direct biventricular support, increase output, and improve ventricular unloading in patients with heart failure. Placed within the pericardium surrounding both ventricles, has two concentric sets of thin-film polyurethane chambers: (1) inner (epicardial) saline-filled chambers that conform intima...

In this paper a sliding mode controller (SMC) is designed for a permanent magnet direct current (PMDC) motor to enhance the motor performance in the presence of unwanted uncertainties. Both the electrical and mechanical signals are used as the inputs to the SMC. The complete motor control system is simulated on a personal computer with different design parameters and desirable system performanc...
