The invention relates to an automatic collapsible umbrella, which utilizes several springs provided around a shaft or therein accompanying with a runner apparatus and a frame to control the umbrella being opened or closed automatically. Since the center of gravity of the carriage is located between the first sliding protrusion and the second sliding protrusions, the carriage can be stably supported by the first and second guide members while the carriage remains stationary or moves at a constant speed in a main scanning direction. The semiconductor device also includes at least one decoupling capacitor coupled to the die through the first substrate.
