Abstract: A semiconductor device and a manufacturing method thereof are provided. The semiconductor device includes a semiconductor substrate, active devices and transparent conductive patterns. The active devices are formed on the semiconductor substrate. The transparent conductive patterns are formed over the active devices and electrically connected to the active devices. The transparent conductive patterns are made of a metal oxide material. The metal oxide material has a first crystalline phase with a prefer growth plane rich in oxygen vacancy, and has a second crystalline phase with a prefer growth plane poor in oxygen vacancy.

Abstract: A skateboard with a handlebar has a board member connected to a support rod from a front end. The handlebar is connected to a top end of the support rod for permitting direction of the skateboard to be changed. A front blade is pivoted to a lower end of the support rod, and a rear blade is pivoted to a rear lower part of the board member for permitting the skateboard to be moved along on ice. The blades can be replaced with shaped skis for permitting the skateboard to be moved along on snow. The skateboard further has a brake depressable to move the rear blade downwards for a stopping block on a bottom of the rear blade to contact the ice. The skis have stopping trenches on a bottom; the trenches do not touch the ground normally, but do when the skateboard leans sideways.
