摘要:
The present disclosure provides a semiconductor device. The semiconductor device includes a substrate and an interconnect structure disposed over the substrate. The interconnect structure includes a plurality of interconnect layers. One of the interconnect layers contains: a plurality of metal via slots and a bulk metal component disposed over the plurality of metal via slots. The present disclosure also provides a method. The method includes providing a wafer, and forming a first layer over the wafer. The method includes forming an interconnect structure over the first layer. The forming the interconnect structure includes forming a second interconnect layer over the first layer, and forming a third interconnect layer over the second interconnect layer. The second interconnect layer is formed to contain a plurality of metal via slots and a bulk metal component formed over the plurality of metal via slots. The third interconnect layer contains one or more metal trenches.

A Wafer Image Modeling and Prediction System (“WIMAPS”) is described that includes systems and methods that generate and/or apply models of resolution enhancement techniques (“RET”) and printing processes in integrated circuit (“IC”) fabrication. The WIMAPS provides efficient processes for use by designers in predicting the RET and wafer printing process so as to allow designers to filter predict printed silicon contours prior to application of RET and printing processes to the circuit design.

Features of a mask, when close enough to one another, can cause unwanted phantom images to print on an integrated circuit. Advantageously, potential locations of phantom images can be automatically identified from a mask layout. This technique can include creating perimeters or rings around features in the mask layout (in one case, after proximity correction). An overlap of perimeters/rings can be assigned a particular weight such that areas of greater overlap have a higher weight and areas of less overlap have a lower weight. If the weight of an overlap area exceeds a trigger weight, then an evaluation point can be added to the mask layout, thereby identifying that layout location as a potential location of a phantom image. After simulation of the mask layout, that layout location can be analyzed to determine if a phantom image would print.

A lottery ticket machine including a chute for guiding a series of lottery tickets, two rollers for conveying the series of lottery tickets, a handle operable for moving the rollers from each other, and a security unit movable between a locking position for avoiding movement of the rollers from each other and a releasing position for allowing the rollers to move from each other. The handle is operable to move the security unit between the locking position and the releasing position.

A game machine includes a cabinet, a supporting rod disposed in the cabinet, a retaining base secured on top of the rod, a lighting device disposed on the retaining device, and a drive mechanism disposed in the cabinet. The rod defines a bore therein. The retaining base defines an aperture in communication with the bore in the rod. The lighting device has its electric wire extending through both of the aperture in the retaining base and the bore in the rod. The target is made of a light-transmissive material. The retaining base and the lighting device are housed in a receptacle of the target. The drive mechanism is configured to drive the rod to move up to have the target pop out of a hole in a table of the cabinet.

A method for manufacturing a high efficiency light-emitting diode (LED) is disclosed. In the method, a substrate is provided, in which an N-type buffer layer, an N-type cladding layer and an active layer are stacked on the substrate in sequence. A first P-type cladding layer is formed on the active layer. Next, a growth-interruption step is performed, and a catalyst is introduced to form a plurality of nuclei sites on a surface of the first P-type cladding layer. A second P-type cladding layer is formed on the first P-type cladding layer according to the nuclei sites, so that the second P-type cladding layer has a surface with a plurality of mesa hillocks. Then, a contact layer is formed on the second P-type cladding layer. Subsequently, a transparent electrode is formed on the contact layer.

A vending machine is equipped with a dispensing device that includes a plate, a track, carriers, a work station, a driving unit and a sensor. The plate is horizontally placed in a vending machine. The track is connected to the plate. The carriers are movably connected to the track for carrying products. The work station causes a selected one of the carriers to release the corresponding one of the products. The driving unit drives the carriers along the track. The sensor senses the selected one of the carriers and accordingly stops the driving unit so that the selected one of the carriers is placed at the work station.
