Abstract: A semiconductor device includes a substrate. A high voltage transistor is disposed within a high voltage region of the substrate. The high voltage transistor includes a first gate dielectric layer disposed on the substrate. A first gate electrode is disposed on the first gate dielectric layer. A first source/drain doping region and a second source/drain doping region are respectively disposed in the substrate at two sides of the first gate electrode. A first silicide layer covers and contacts the first source/drain doping region and a second silicide layer covers and contacts the second source/drain doping region. A first conductive plate penetrates the first silicide layer and contacts the first source/drain doping region. A second conductive plate penetrates the second silicide layer and contacts the second source/drain doping region.

Abstract: A light-emitting diode structure includes a substrate, a semiconductor light-emitting structure, and an electrode. The semiconductor light-emitting structure is located on the substrate, and the semiconductor light-emitting structure includes a top surface and a plurality of side walls. A surface roughening area is formed on the top surface. The electrode is located on the top surface. The surface roughening area is located between the electrode and the plurality of side walls, and the top surface forms a first flat part between the surface roughening area and the plurality of side walls.

Abstract: A bearing journal for bicycles includes a lower race having two stops extending from an outer periphery of the lower race and an upper race having a skirt extending from an outer periphery thereof. A bearing is received between the lower race and the upper race. A protrusion extends inward from an inner periphery of the skirt which encloses the two stops. The steering tube of the front fork extends through the bearing journal and is connected to a handlebar stem. When the handlebar is rotated 180 degrees, the upper race co-rotated with the handlebar is stopped by the contact between the protrusion and one of the stops.
