Abstract: Image analysis using machine learning technology utilizes a texture structure which is analyzed while a manufacturing process is changed for a purpose of searching for an optimum condition or the like. One aspect is an information processing system including: an identifier configured to output an identification result with an image as input; an automatically identifiable range storage unit configured to store an identifiable range of the identifier defined by numerical values in n (n is an integer of 1 or more) dimensions; an acquisition unit configured to acquire the numerical values corresponding to the image; a control unit configured to compare the numerical values acquired by the acquisition unit and the identifiable range; and an alert output unit configured to output an alert when the control unit determines that the numerical values acquired by the acquisition unit deviate from the identifiable range.

Abstract: A rutile phase can be formed even in the case of a thin film by adding nickel or cobalt to titanium dioxide in the range of 0.5 to 10 atm %, and the use of this element-added titanium dioxide film in a capacitor dielectric film results in an increase in capacitance per unit area of a DRAM memory cell and enables a high-integration DRAM to be realized at low cost.
