A control method of a continuous casting process is a method that injects molten metal from a surface layer nozzle and an inner layer nozzle into a mold and separates the molten metal of a surface layer and the molten metal of an inner layer, the control method including, using a molten metal level meter that measures a surface layer level and a flowmeter that measures a supply flow rate of the molten metal, estimating a boundary layer level on the basis of a measured value of the surface layer level, a measured value of the supply flow rate of the molten metal, and a calculated value of the supply flow rate of the molten metal, and controlling the supply flow rate of the molten metal of the surface layer nozzle and the supply flow rate of the molten metal of the inner layer nozzle.

A method of fabricating a photodiode array having different photodiode structures includes providing a semiconductor substrate having first and second diode areas including a bottom substrate portion doped with a first doping type, an intrinsic layer, and a top silicon layer doped with a second doping type. The second diode areas are implanted with the second doping type. A dopant concentration in the surface of the second diode areas is at least three times higher than in the first diode areas. The top silicon layer is thermally oxidized to form a thermal silicon oxide layer to provide a bottom Anti-Reflective Coating (ARC) layer. The second diode areas grow thermal silicon oxide thicker as compared to the first diode areas. A top ARC layer is deposited on the bottom ARC layer. First PDs are provided in the first diode areas and second PDs provided in the second diode areas.
