Abstract: A semiconductor structure including a substrate, a first dielectric layer disposed on the substrate, a second dielectric layer disposed on the first dielectric layer and in physical contact with the first dielectric layer, an opening on the substrate and having a lower portion through the first dielectric layer and an upper portion through the second dielectric layer, an conductive layer disposed on the second dielectric layer at two sides of the opening and in physical contact with the second dielectric layer, a contact structure disposed in the lower portion of the opening, and a passivation layer covering a top surface of the contact structure, a sidewall of the second dielectric layer, and a sidewall of the conductive layer.

Abstract: A folder-type cell phone including a first body and a second body is provided. The housing of the first body is composed of a case and a cover. The second body is connected with the first body by using a hinge structure. The hinge structure includes a shaft, a flexible printed circuit (FPC), a holder, and a bearing. The shaft is formed at an edge of the second body and has a first opening and a second opening at both ends of the shaft. The FPC is arranged in the shaft and has a first end extending toward the second body and a second end passing through the first opening for electrically connecting with the first body. The holder is assembled in the first opening with partially protruding from the shaft for holding the FPC. The hinge is assembled in the second opening with partially protruding from the shaft. Two cylindrical concaves facing upward are formed on a bottom of the case for support the protruding portions of the bearing and the holder so as to pivotally connect the second body with the first body.

Abstract: A retention mechanism comprises a post and a movable arm slidingly secured to the post. The post includes a plurality of serrations formed along an elongated side thereof. The movable arm includes a canister adapted to enclose and latch with the serrations of the post, and a securing portion extending from the canister for securing an upper edge of an edge card. The canister forms a pair of stoppers in two opposite holes defined in an outside wall thereof. Each stopper includes a lever and two ribs supporting the lever in the sidewall of the canister. Each lever forms an inwardly extending protrusion thereon. When lower ends of the levers are pushed inwardly toward each other, the levers pivot about the ribs and the protrusions move outwards from the serrations of the post, allowing the movable arm to slide along the elongated side of the post.

Abstract: A ZIF connector comprises an insulative housing, a plurality of terminals received in the housing, an insulative cover plate curvedly slidably mounted on the housing having a pressing plate for pressing an FPC against the terminals, an actuation mechanism for curvedly slidably connecting the cover plate and the housing and two locking mechanisms for securely locking the cover plate to the housing. The housing comprises a pair of standing walls at both ends thereof. The cover plate comprises a pair of arms formed at opposite ends thereof. The actuation mechanism comprises a pair of arcuate channels defined in the two standing walls and a pair of corresponding arcuate ribs formed on opposite arms of the cover plate and slidingly moveable in the arcuate channels when the cover plate is curvedly slidably moved relative to the housing.
