 Vertical-channel type junction sic power fet and  manufacturing same patent thumbnailVertical-channel type junction sic power fet and manufacturing same
In order to secure the performance of a sic-based jfet having an impurity diffusion rate lower than silicon-based one, a gate depth is secured while precisely controlling a distance between gate regions, instead of forming gate regions by ion implantation into the side wall of a trench. This means that a channel region defined by a gate distance and a gate depth should have a high aspect ratio.

Methods for providing lithography features on a substrate by self-assembly of block copolymers


A method of designing an epitaxy template to direct self-assembly of a block copolymer on a substrate into an ordered target pattern involves providing a primary epitaxy template design and then varying the design to optimize a pattern fidelity statistic, such as placement error, relative to the target pattern by modelling predicted self-assembled block copolymer patterns and optimizing pattern placement as a function of a varied design parameter. In addition to varying a design parameter to optimize the pattern fidelity statistic, a random error in the template design is included prior to modelling predicted patterns in order to compensate for expected template inaccuracy in practice.
