Reinforced semiconductor structures are provided. A method for clock adjustment includes receiving feedback clocks from independent ASIC modules. The tapered line portion keeps a predetermined characteristic impedance constant and expands at least one of a width of the transmission line and an interval in a tapered shape at a predetermined taper angle. The fermentation by the koji mold causes the oil content to fall to a predetermined amount, while the heat of fermentation is used to reduce the water content of organic raw materials, thus producing a koji feed composition.
