Abstract:
A device fabricated on a chip is disclosed. The device generally includes (A) a first pattern and a second pattern both created in an intermediate conductive layer of the chip, (B) at least one via created in an insulating layer above the intermediate conductive layer and (C) a first bump created in a top conductive layer above the insulating layer. The first pattern generally establishes a first of a plurality of plates of a first capacitor. The via may be aligned with the second pattern. The first bump may (i) be located directly above the first plate, (ii) establish a second of the plates of the first capacitor, (iii) be suitable for flip-chip bonding and (iv) connect to the second pattern through the via such that both of the plates of the first capacitor are accessible in the intermediate conductive layer.
