Abstract: A metal interconnect structure includes a first metal interconnection in an inter-metal dielectric (IMD) layer on a substrate, a second metal interconnection on the first metal interconnection, and a cap layer between the first metal interconnection and the second metal interconnection. Preferably, a top surface of the first metal interconnection is even with a top surface of the IMD layer and the cap layer is made of conductive material.

Abstract: The present invention discloses an optical fiber coupling system controlling an optical fiber coupling device, and the system is characterized by a manufacturing process controlling device. With the present invention, the coupling ratio of the optical fibers to be coupled can be modulated via a window interface unit. Thus, the system provides real-time information and convenient modulation of the optical fiber coupling device simultaneously and clearly.

Abstract: A jig for optical fibers to manufacture fused couplers includes a guide rail, at least one slider, two vacuum bases and at least one ceramic power output element. The slider is mounted on the guide rail. The vacuum bases are used to fix the optical fibers, while one of the vacuum bases is fixed to the slider. The ceramic power output elements drive the slider to move on the guide rail.

Abstract: A mass production polisher includes a polisher base, a polishing element, a rotary arm, a fixture, a force-cushioning means and a force-applying means. The polishing element is provided in the polisher base. The rotary arm is rotatably provided on the polisher base. The fixture is connected to the rotary arm for holding at least one object. The force-cushioning means is provided on the rotary arm. The force-applying means is also provided on the rotary arm for applying force through the force-cushioning means to the fixture so that the object pushes against the polishing element.

Abstract: An automatic apparatus for assembling an optical fiber cable, a pre-assembled element and a sleeve. The automatic apparatus includes a glue-injecting mechanism, a feeding mechanism, a forging press, a movable stand, a clamping and rotating mechanism and a robot. Glue is injected into the pre-assembled element by the glue-injecting mechanism. Then, the robot conveys the pre-assembled element from the glue-injecting mechanism to the clamping and rotating mechanism. The optical fiber cable and sleeve are supported by the movable stand. The stand is moved toward the pre-assembled element so that the optical fiber cable enters the pre-assembled element. Then, the optical fiber cable is further pushed into the pre-assembled element by the feeding mechanism. Then, the pre-assembled element is covered with the sleeve by the feeding mechanism. Then, the sleeve is pressed by the forging press so that the sleeve is deformed to engage the pre-assembled element.
