Abstract: A manufacturing method of a semiconductor structure includes the following steps. A first wafer is provided. The first wafer includes a first substrate and a first device layer. A second wafer is provided. The second wafer includes a second substrate and a second device layer. The second device layer is bonded to the first device layer. An edge trimming process is performed on the first wafer and the second wafer to expose a first upper surface of the first substrate and a second upper surface of the first substrate and to form a damaged region in the first substrate below the first upper surface and the second upper surface. The second upper surface is higher than the first upper surface. A first photoresist layer is formed. The first photoresist layer is located on the second wafer and the second upper surface and exposes the first upper surface and the damaged region. The damaged region is removed by using the first photoresist layer as a mask. The first photoresist layer is removed.

Abstract: A self-lock hinge is mounted between a cover and a base of an electronic device and has a resilient sleeve and a pintle. The resilient sleeve has a tubular body with a positioning protrusion formed on an inside wall thereof. The pintle has a rod. The rod is mounted rotatably through the tubular body and has a flat wall selectively abutting the positioning protrusion. When the cover is closed relative to the base, the flat wall of the rod abuts the positioning protrusion to lock the cover. Therefore, the cover is self-locked when closing.

Abstract: A simplified hinge is mounted between a cover and a base of a portable electronic device. The simplified hinge has a pintle connected to the base, a main linking sheet connected to the cover and a resilient washer and a positioning washer abutting each other and mounted around the pintle. The resilient washer has a resilient segment protruding toward one side. The positioning washer has corresponding positioning protrusion or detent. With the elasticity of the resilient segment, the resilient washer generates torsion when rotating between the positioning washer and the pintle. Furthermore, the positioning protrusion or detent selectively engages with the resilient segment to provide positioning function. Therefore, the resilient washer provides not only the torsion but also the positioning function so that the simplified hinge has a simplified structure and its volume is effectively reduced.

Abstract: A hinge is mounted in an electronic device with a cover and a base. The hinge has a first pivoting assembly, a second pivoting assembly and a resilient unit. The first pivoting assembly has a resilient plug. The resilient plug is mounted between the second pivoting assembly and the resilient unit to provide friction and to keep the second pivoting assembly from departing from the first pivoting assembly. The friction is adjusted by changing the resilience of the resilient plug or the resilient unit, or by changing the thickness of the resilient plug. Therefore, preciseness of the size of other component is less required to reduce the manufacturing cost.

Abstract: A hinge is mounted between a cover and a base of an electronic device. A lid covers the hinge and is attached securely to the base. The hinge has an arced surface and a rotating shaft. When the cover is pivoted to a certain angle, the rotating shaft abuts the arced surface to lift up the cover so the cover is selectively distant away from the lid. Therefore, the shape of the electronic device does not need to be disfigured and the cover still does not bump against the lid.

The spring is attached to the top of the stationary leaf and has a stationary end and a moving end. The pivot pin assembly connects the stationary leaf and the moving leaf and allows the moving leaf to slide relative to the stationary leaf. The guide pin assembly extends through the moving end of the spring, the stationary leaf and the moving leaf to connect the stationary leaf, the spring and the moving leaf and allows the moving leaf to slide and turn relative to the stationary leaf.

Abstract: A position-fixing hinge has a housing, a pintle and a fixing member. The housing defines an inner space and is mounted in a base of a portable electronic device. The pintle is mounted longitudinally in the housing, is rotatably relative to the housing and has an outer end and an inner end. The outer end connects with a connector to mount a cover of the portable electronic device. The inner end defines a tongue. The fixing member is movably mounted in the housing, has an engaging portion corresponds to and selectively engages the tongue of the pintle by a faces inter-pressing manner. Such that the cover connected with the pintle is securely held at any determined position. Furthermore, abrasion and deformation are effectively prevented, such that the position-fixing hinge is available for a long term of use.

The resilient element is mounted around the pintle between the flange and the mounting leaf. The mounting bracket is connected rotatably to one end of the body and a base of an electronic device. With such an arrangement, the dual-axis hinge only has a few components in a simple structure and allows the cover to lift from the base and rotate horizontally relative to the base.
