Abstract: An integrated circuit (IC) comprising an enhanced passivation scheme for pad openings and trenches is provided. In some embodiments, an interlayer dielectric (ILD) layer covers a substrate and at least partially defines a trench. The trench extends through the ILD layer from a top of the ILD layer to the substrate. A conductive pad overlies the ILD layer. A first passivation layer overlies the ILD layer and the conductive pad, and further defines a pad opening overlying the conductive pad. A second passivation layer overlies the ILD layer, the conductive pad, and the first passivation layer, and further lines sidewalls of the first passivation layer in the pad opening and sidewalls of the ILD layer in the trench. Further, the second passivation layer has a low permeability for moisture or vapor relative to the ILD layer.

Abstract: Methods for forming dummy under-bump metallurgy structures and semiconductor devices formed by the same are disclosed. In an embodiment, a semiconductor device includes a first redistribution line and a second redistribution line over a semiconductor substrate; a first passivation layer over the first redistribution line and the second redistribution line; a second passivation layer over the first passivation layer; a first under-bump metallurgy (UBM) structure over the first redistribution line, the first UBM structure extending through the first passivation layer and the second passivation layer and being electrically coupled to the first redistribution line; and a second UBM structure over the second redistribution line, the second UBM structure extending through the second passivation layer, the second UBM structure being electrically isolated from the second redistribution line by the first passivation layer.

Abstract: The present disclosure is related to a vapor chamber lid. The vapor chamber lid includes a base plate and a top plate. The base plate includes a plate body, a frame, a plurality of supporting pillars and a chip accommodating portion. The frame surrounds the plate body to define a cooling space. The cooling space is configured to accommodate a working fluid. The supporting pillars are located in the cooling space. The chip accommodating portion is located on the plate body of the base plate and is facing away from the cooling space. The top plate is located on the frame of the base plate to seal the cooling space. An external sidewall of the frame of the base plate is coplanar with an external sidewall of the top plate.

Abstract: A lubricating system is installed in a common injection molding machine which includes a stationary mold half unit, a movable mold half unit which can be moved towards and away from the stationary mold half unit, a toggle mechanism coupled with the movable mold half unit so as to be driven to move the movable mold half unit, a mold pressing hydraulic cylinder having a piston rod coupled with the toggle mechanism so as to drive the toggle mechanism, and an oil feed system coupled with the mold pressing hydraulic cylinder so as to provide hydraulic pressure for the mold pressing hydraulic cylinder to drive the toggle mechanism.
