  • SEMICONDUCTOR INTERCONNECTION STRUCTURE AND METHODS OF FORMING THE SAME
    Publication number: 20240088023
    Abstract: An interconnect structure includes a dielectric layer, a first conductive feature, a hard mask layer, a conductive layer, and a capping layer. The first conductive feature is disposed in the dielectric layer. The hard mask layer is disposed on the first conductive feature. The conductive layer includes a first portion and a second portion, the first portion of the conductive layer is disposed over at least a first portion of the hard mask layer, and the second portion of the conductive layer is disposed over the dielectric layer. The hard mask layer and the conductive layer are formed by different materials. The capping layer is disposed on the dielectric layer and the conductive layer.

  • Engagement assembly for connecting reflector and connecting rod
    Patent number: 8636370
    Abstract: The present invention provides an engagement assembly for connecting a reflector and a connecting rod. The engagement assembly has a fixing base and a fixing plate. The fixing base has a head accommodating room for holding a head portion of the connecting rod and a plate retaining space formed between two protrusion rings. The fixing plate is mounted in the plate retaining space and has a position-limiting portion and two fixing portions. The position-limiting portion has a through hole for inserting the head portion and at least two tongues. The tongues are mounted on an inner edge of the through hole for clamping the head portion of the connecting rod that has entered the head accommodating room. The engagement assembly provides a strong linking structure for the reflector and the connecting rod.
