摘要:
Disclosed is a reinforced bond pad structure having nonplanar dielectric structures and a metallic bond layer conformally formed over the nonplanar dielectric structures. The nonplanar dielectric structures are substantially reproduced in the metallic bond layer so as to form nonplanar metallic structures. Surrounding each of the nonplanar metallic structures is a ring of dielectric material which provides a hard stop during probing of the bond pad so as to limit the amount of bond pad that can be removed during probing.

摘要:
A system for testing a collection of device chips by temporarily attaching them to a carrier having a plurality of receptacles with microdendritic features; the receptacles matching with and pushed in contact with a matching set of contact pads on the device chips; said carrier additionally having test pads connected to the receptacles through interconnect wiring. The system allows connecting the chips together and testing the collection as a whole by probing the test pads on the carrier. Burn-in of the collection of chips can also be performed on the temporary carrier, which is reusable.

A method for fabricating a solder transfer mold includes masking a substrate with a masking agent. A pattern is transferred to the substrate mask. The masked substrate is etched until cavities of a first volume are formed. The cavities of the first volume are selectively coated. The masked substrate is etched until cavities of a second volume are formed.

A solder mold includes a substrate and a plurality of cavities for holding solder to be transferred to an integrated circuit. The plurality of cavities comprises cavities of at least two different volumes.
