Abstract: A method of fabricating a semiconductor device, including a high-voltage device region and a low-voltage device region, includes the steps of: providing a substrate, wherein a bottom mask layer and a top mask layer are sequentially disposed thereon; forming a doped region in the substrate based on a first layout pattern; patterning the substrate based on a second layout pattern to form at least two trenches in the substrate respectively in the high-voltage device region and the low-voltage device region; and patterning the top mask layer in the high-voltage device region based on a third layout pattern to form a patterned top mask layer and expose the bottom mask layer from the patterned top mask layer, wherein the third layout pattern is generated by comparing the first layout pattern and the second layout pattern and executing a Boolean operation.

Abstract: The disclosure provides a photovoltaic vehicle roof. The photovoltaic vehicle roof comprises a structural layer including a flat-plate or single-curve surface shaped power generation zone and a transition zone disposed around the power generation zone, and a photovoltaic module layer including a flexible photovoltaic thin-film module secured to an upper surface of the power generation zone. The present disclosure adopts a single-curve surface or flat-plate shaped power generation zone, and only needs to lay the flexible photovoltaic thin-film module on the power generation zone. The process is simple and convenient, and can effectively prolong the service life of the photovoltaic vehicle roof since no complex stress will be generated.

Abstract: A solar support mounted on a vehicle roof includes a module bracket and a photovoltaic module disposed on the module bracket. The module bracket fits the vehicle roof. The module bracket is provided with at least two fixing units. Each of the at least two fixing units detachably fits an upper edge of a vehicle door frame.
