A semiconductor device structure has a semiconductor die that has a bond pad with a passivation layer surrounding a portion of the bond pad. A nickel layer, which is deposited, is on the inner portion. A space is between a sidewall of the nickel layer and the passivation layer and extends to the bond pad. A palladium layer is over the nickel layer and fills the space. The space is initially quite small but is widened by an isotropic etch so that when the palladium layer is deposited, the space is sufficiently large so that the deposition of palladium is able to fill the space. Filling the space results in a structure in which the palladium contacts the nickel layer, the passivation layer and the bond pad.

A method for forming a semiconductor structure includes forming a first contact pad on a first die, wherein the first contact pad comprises a first metal element, forming a metal over the first contact pad, wherein the metal comprises a second metal element, and the second metal element is different from the first metal element. The method further includes rapidly reflowing a portion of the metal to form a thin intermetallic layer. The method further includes attaching the first contact pad of the first die to a second contact pad of a second die, wherein attaching comprises heating the first contact pad and the second contact pad to reflow the metal to form an intermetallic layer such that substantially all of the metal formed over the first contact pad is used as part of the intermetallic layer.
摘要:
A method for making a semiconductor device (10) includes providing an interconnect layer (14) over an underlying layer (12), forming a first insulating layer (16) over the interconnect layer, and forming an opening (18) through the insulating layer to the interconnect layer. A first conductive layer (24) is formed over the interconnect layer and in the opening. This is performed by plating so it is selective. A second conductive layer (28) in the opening is formed by displacement by immersion. This is performed after the first conductive layer has been formed. The result is the second conductive layer is formed by a selective deposition and is effective for providing it with bridging material. A layer of bridgeable material (34) is formed over the second conductive layer and in the opening. A third conductive layer (42) is formed over the bridgeable material. The semiconductor device may be useable as a conductive bridge memory device.
