  • Patent number: 11023645
    Abstract: An approach is described for a method, system, and product for detection of contours for data pads of a device having a free form contour, clustering integrated circuit pads and data pads, performing any angle routing based on a contour angle, and performing resistance balancing. For example, data pads of a display device having one or more curved contours (e.g. data pads arranged on an arc) are identified. Corresponding data pads and integrated circuit pads are then grouped together for routing interconnections and subsequently routed using any angle routing instead of merely routing interconnections with turns having 90-degree or 45-degree angles. Finally, the routed interconnects may be further refined/modified to balance resistances of the interconnections.

  • Patent number: 11024577
    Abstract: A method for manufacturing a semiconductor device includes forming first and second interconnect structures on an etch stop layer, wherein the second interconnect structure is spaced apart from the first interconnect structure. The etch stop layer extends between the first and second interconnect structures. In the method, part of the etch stop layer between the first and second interconnect structures is removed. The removing forms a first portion of the etch stop layer extending from under the first interconnect structure toward the second interconnect structure, and a second portion of the etch stop layer extending from under the second interconnect structure toward the first interconnect structure. The first and second portions are spaced apart from each other. A dielectric layer is formed which fills in the spaces between the first and second portions of the etch stop layer and between the first and second interconnect structures.

The forming method includes: providing a base; forming a first electrode layer on the base; forming a capacitance dielectric layer on a top and a sidewall of the first electrode layer; and forming a second electrode layer conformally covering the capacitance dielectric layer. Compared with a solution in which the capacitance dielectric layer only covers the top of the first electrode layer, in the present disclosure, an effective area between the second electrode layer and the first electrode layer is increased, the second electrode layer, the first electrode layer, and the capacitance dielectric layer located on the top of the first electrode layer construct one capacitance, and the second electrode layer, the first electrode layer, and the capacitance dielectric layer located on the sidewall of the first electrode layer construct other four capacitances. That is, the formed capacitor structure includes five parallel capacitances.

A circuit resist pattern and a monitoring resist pattern may be formed on the plating layer, and the plating layer may be etched using the circuit resist pattern and the monitoring resist pattern as etch masks, thereby forming circuit patterns and sub-patterns of a monitoring pattern. A residual rate of the circuit patterns may be monitored by inspecting the number of the sub-patterns of the monitoring pattern remaining on the substrate body after an etch process for forming the circuit patterns and the sub-patterns of the monitoring pattern. A semiconductor chip may be bonded to the circuit patterns using inner connectors.
