A scalable multi-power integrated circuit package for integrated circuits having spaced apart first, second and third pluralities of respective spaced apart chip power bonding pads connected to-corresponding first, second, and third chip power supply nets, the chip power bonding pads disposed adjacent to a chip periphery defining the chip area, the scalable multi-power integrated circuit package comprising: a central chip mounting area for mounting one of said integrated circuits, said chip mounting area defining a chip mounting area periphery surrounding said chip mounting area; spaced apart first, second and third package power supply continuous conductive traces, each trace disposed adjacent to the chip area mounting periphery; corresponding first, second and third pluralities of spaced apart package bonding areas defined along each respective one of said first, second and third package power supply continuous conductive traces, each respective one of said package bonding areas disposed in bondable alignment with a corresponding one of said chip power bonding pads along said chip periphery such that a permanent conductive bond can be made between said package bonding area and said chip bonding pad. Alternatives include a chip scale package outline, in which one of the chip power supply nets is a common ground return for the other two power supply nets.

Multi-power ring chip scale package for system level integration

An integrated circuit including a power ring and an embedded low drop-off voltage regulator is disclosed herein. The regulator is located within an inner side of the power ring. An input of the regulator is coupled to the power ring. An output of the regulator is coupled to a circuit also included in the integrated circuit. The regulator is configured to fit within a bond pad frame.

A methodology of creating integrated circuits with improved noise isolation is presented. The circuitry of an integrated circuits is separated into noise generating circuit blocks and noise sensitive circuit blocks. N-type and P-type diffusion guard rings are placed around each of the circuit blocks. Substantially overlying the N-type and P-type diffusion guard rings are power supply meshes which are intimately in contract with the guard rings below through spaced apart vias. The power supply meshes not only supply power for the circuit blocks, but also reverse-bias the diffusion guard rings for improved noise isolation.
