Abstract
The present invention discloses an integrated method for I/O redistribution and in-situ passive components fabrication such that passive components such as resistors and capacitors can be formed simultaneously during the I/O redistribution process. Only minor modifications in the I/O redistribution process need to be made for accomplishing the present invention method. In the method, an adhesion layer formed of a high resistance material such as TiW, TiN, NiCr,or NiV can be used to connect between connective traces and to function as passive resistors. Passive capacitors can be formed by the additional deposition steps of a dielectric layer and a conductive metal layer on top of an existing connective trace formed on a bonding pad.
