Optimizing the edge termination design around the periphery of active area is critically important for achieving the highest and stable breakdown voltage (BVdss) for any power devices. Active cell structures can be assumed as two dimensional (2-D) in the central part of the die, however as the active cells terminate to the termination regions at the periphery of the die, 2-D and 3-D transition regions...
This paper discusses the breakdown voltage (BVDSS) characteristics of an n-channel charge balanced shielded gate trench power MOSFET. The study emphasizes on elements that affect the BVDSS stability of such devices to gain good control on design and process/device parameters in order to produce a robust product. Breakdown voltage (BVDSS) walk-in or walk-out can be observed when certain process (e...
Inner ear hair cells detect sound through deflection of mechanosensory stereocilia. Each stereocilium is supported by a paracrystalline array of parallel actin filaments that are packed more densely at the base, forming a rootlet extending into the cell body. The function of rootlets and the molecules responsible for their formation are unknown. We found that TRIOBP, a cytoskeleton-associated protein...
A method is described for constructing looped actin filaments. Circular islands of nitrocellulose were patterned onto a microscope cover slip by micro-contact printing. A flow cell was then constructed over the patterned surface. Skeletal myosin was introduced into the assay which non-specifically attached to the nitrocellulose islands. Labeled actin filaments were added to the assay and self assembled...
