An object is to provide a semiconductor device and its manufacturing method in which delay in switching and non-uniform operations are prevented and in which stresses occurring in trench regions are alleviated as much as possible. The methodology leverages the structure of suffix trees to build a suffix tree by simultaneously tiling accesses to both the input string as well as the partially constructed suffix tree. A liquid crystal layer is coated on the alignment layer to cover the first regions and the second regions of the pattern configuration to a plane with a determined thickness on the surface of the first regions. The index module indexes the content data and metadata received from the desktop integration module. A Bayesian filter is configured to train itself using the identified messages and the confidence levels and adjust the confidence levels. , thus obtaining a shifted synthesis gas ; purification of said shifted synthesis gas including at least a step of pressure-swing adsorption to remove residual carbon oxides and methane from the synthesis gas, obtaining a purified synthesis gas, and optionally, addition of nitrogen to said purified synthesis gas, thus obtaining ammonia synthesis gas with a desired hydrogen to nitrogen ratio.
