  • Patent number: 11881450
    Abstract: A system and method for fabricating on-die metal-insulator-metal capacitors capable of supporting relatively high voltage applications and increasing capacitance per area are described. In various implementations, an integrated circuit includes multiple metal-insulator-metal (MIM) capacitors. The MIM capacitors are formed between two signal nets such as two different power rails, two different control signals, or two different data signals. The integrated circuit includes multiple intermediate metal layers (or metal plates) formed between two signal nets. In high voltage regions, a MIM capacitor has one or more intermediate metal plates formed as floating plates between electrode metal plates. The floating plates have no connection to any power supply reference voltage level used by the integrated circuit.

  • Publication number: 20230207447
    Abstract: A system and method for fabricating on-die metal-insulator-metal capacitors capable of maintaining a similar capacitance for design reuse across multiple semiconductor fabrication processes are described. In various implementations, an integrated circuit includes multiple metal-insulator-metal (MIM) capacitors. The MIM capacitors are formed between two signal nets. The integrated circuit includes multiple intermediate metal layers (or metal plates) formed between two signal nets. Subsequent semiconductor fabrication processes typically increase a number of metal plates that can be formed in the dielectric layer, such as an oxide layer, between two signal nets. To permit design reuse across multiple semiconductor fabrication processes, for a particular MIM capacitor designated to maintain a same capacitance, the additional metal plates for the particular MIM capacitor are formed as floating nets.

  • Patent number: 11495535
    Abstract: A system and method for detecting and measuring electrostatic discharge during semiconductor assembly are described. A semiconductor device fabrication process forms a conductor between two metal routes in a series path on a semiconductor die. The series path is between a bump on the die and a substrate tie. The two metal routes have a width greater than a threshold based on a metal width capable of conducting a critical current density caused by an electrostatic discharge event without conductive failure or breakdown. The conductor has a width less than the threshold. When an electrostatic discharge event occurs, if the current exceeds a critical amount of current, the conductor experiences conductive breakdown and current ceases to flow. During later testing, this series path is tested for open connections, which indicate whether the conductor acting as an electrical on-die fuse experienced conductive failure during assembly of a semiconductor chip.

  • Patent number: 11189569
    Abstract: Integrated circuit layouts are disclosed that include metal layers with metal tracks having separate metal sections along the metal tracks. The separate metal sections along a single track may be electrically isolated from each other. The separate metal sections may then be electrically connected to different voltage tracks in metal layers above and/or below the metal layer with the separate metal sections. One or more of the metal layers in the integrated circuit layouts may also include metal tracks at different voltages (e.g., power and ground) that are adjacent to each other within a power grid layout. The metal tracks may be separated by electrically insulating material. The metal tracks and the electrically insulating material between the tracks may create capacitance in the power grid layout.
