Claim 4:
5. A method for evaluating a capacitance manufacture procedure, comprising:
setting a plurality of sampling regions;
obtaining a plurality of capacitance groups by obtaining a plurality of capacitances in each sampling region of the plurality of sampling regions along a preset arrangement direction as one capacitance group;
obtaining a difference between a maximum value and a minimum value of shortest distances between adjacent capacitances in each capacitance group of the plurality of capacitance groups as an initial parameter, wherein each of the shortest distances between the adjacent capacitances in each capacitance group is obtained by: obtaining a distance between tangent lines of adjacent surfaces of two adjacent capacitances in the capacitance group, and taking the distance between the tangent lines of the adjacent surfaces of the two adjacent capacitances in the capacitance group as a shortest distance between the two adjacent capacitances in the capacitance group, wherein the tangent lines of the adjacent surfaces of the two adjacent capacitances in the capacitance group have a same direction, and the direction of the tangent lines is perpendicular to the preset arrangement direction of the two adjacent capacitances in the capacitance group; and
obtaining a mean value of the initial parameters of the plurality of capacitance groups, the mean value being used as a parameter for evaluating the capacitance manufacture procedure.
