Motorola Inc. / SPS GroupSacrificial Metal Wafer Level Burn-in KGDMotorola has been developing and evaluating WLBItechnologies since the early ‘90s as seen in the earlierpresentation on the Motorola/TEL/Gore alliance. Thisparticular development and implementation of 127mmand 200mm Sacrificial Metal Wafer Level Burn-In KGD atMotorola is a strategic enabling technology that allowsMotorola to maintain a competitive edge in the electronicpersonal communications, computer and automotivemarketplace.This has been a joint effort between teams at:! Motorola Austin - TSG (Transportation Systems Group)! Motorola Chandler - SMD (Strategic ManufacturingDeployment)! Motorola Chandler - MOS 12 Group33
Motorola Inc. / SPS GroupThe WLBI process flow at the wafer-level:! WLBI process flow is identical to packagelevel devices all the way to Metal-3 at theMOS! The special passivation mask enable contactalong the scribe grid whose contactsaccommodate excercising of the deviceduring burn-in! A final polyimide over-layer acts as a stressbuffer in aggressive environments (ie.,automotive) - need to be free of unstablecomponents to prevent outgassing! Wafer-level burn-in circuit removalcomprised of wet etch processes withchemistries identical to that used in definingthe WLBI circuit - TiW and/or Cu must becompletely removed34
