Claim:
1. A method for forming a semiconductor device, the method comprising: forming a first contact and a second contact on a first package; forming a first underbump metallization in physical contact with the first contact; forming a second underbump metallization in physical contact with the second contact; adjusting a height of the first contact relative to the second contact by forming a first post-contact material over the first contact, wherein the first contact, the first underbump metallization and the first post-contact material each have a different composition from each other; forming a first external conductive connector in physical contact with the first post-contact material, wherein the first external conductive connector comprises a single material throughout the first external conductive connector, the single material having a different composition than the first post-contact material; and bonding a second package to the second contact, wherein the first external conductive connector extends away from the first package a first distance, the second package extends away from the first package a second distance, the second distance being parallel to and less than the first distance, and wherein the second package comprises a second conductive connector in physical contact with the second underbump metallization.
