A method of fabricating a metal-oxide-semiconductor transistor is provided. A socket element is assigned to the second line and receives the plug pin in a pin receiver for electrically contact. The current distribution MISFET and the second current distribution MISFET constitute a current mirror. A normal vector perpendicular to the direction of the reflectance component gradient may be determined, based on a difference between the color channels of the image gradient. The background template frame can be combined with each of the plurality of partial frames to generate a plurality of altered frames, and the plurality of altered frames can be processed into a second animation.
