Method for a capacitor connection structure

Disclosed is a method for a capacitor connection structure. Benefits include improved functionality, improved performance, and improved power performance.

Background

     

      The frequency of operation of a processor is set by the lower limit of the voltage in the voltage tolerance range. When the range around the nominal operating voltage is narrower, the voltage control circuit (VCC) and the operating frequency are higher.

      Conventionally, the core and input/output (I/O) power delivery connections are not sufficient and have a higher inductive path to the capacitors. The result is higher voltage noise levels and the processor runs at lower core and I/O frequencies. This problem is solved by adding capacitors in parallel to reduce loop inductance and voltage fluctuations within a set tolerance. However, this solution is not cost effective.

General description

      The disclosed method is alternate shorting of the high-frequency two terminal (2T) or interdigitated capacitor (IDC) to improve power delivery robustness. This connection can be made using die-side and/or land-side components.

      The key element of the disclosed method includes high frequency capacitors connected in parallel through an alternate metal pad geometry for improved core and/or I/O power delivery.

Advantages

      The disclosed method provides advantages, including:
•     Improved functionality due to providing a capacitor connection structure

•...
