摘要： A barrier layer is deposited over a layer of passivation including in an opening to a contact pad created in the layer of passivation. A column of three layers of metal is formed overlying the barrier layer and aligned with the contact pad and having a diameter that is about equal to the surface of the contact pad. The three metal layers of the column comprise, in succession when proceeding from the layer that is in contact with the barrier layer, a layer of pillar metal, a layer of under bump metal and a layer of solder metal. The layer of pillar metal is reduced in diameter, the barrier layer is selectively removed from the surface of the layer of passivation after which reflowing of the solder metal completes the solder bump of the invention.

摘要： An integrated chip package structure and method of manufacturing the same is by adhering dies on an organic substrate and forming a thin-film circuit layer on top of the dies and the organic substrate. Wherein the thin-film circuit layer has an external circuitry, which is electrically connected to the metal pads of the dies, that extends to a region outside the active surface of the dies for fanning out the metal pads of the dies. Furthermore, a plurality of active devices and an internal circuitry is located on the active surface of the dies. Signal for the active devices are transmitted through the internal circuitry to the external circuitry and from the external circuitry through the internal circuitry back to other active devices. Moreover, the chip package structure allows multiple dies with different functions to be packaged into an integrated package and electrically connecting the dies by the external circuitry.

摘要： A barrier layer is deposited over a layer of passivation including in an opening to a contact pad created in the layer of passivation. A column of three layers of metal is formed overlying the barrier layer and aligned with the contact pad and having a diameter that is about equal to the surface of the contact pad. The three metal layers of the column comprise, in succession when proceeding from the layer that is in contact with the barrier layer, a layer of pillar metal, a layer of under bump metal and a layer of solder metal. The layer of pillar metal is reduced in diameter, the barrier layer is selectively removed from the surface of the layer of passivation after which reflowing of the solder metal completes the solder bump of the invention.

摘要： A Chip Scale Package (CSP) and a method of forming the same are disclosed. Single chips without the conventional ball mountings, are first attached to an adhesive-substrate (adsubstrate) composite having openings that correspond to the input/output (I/O) pads on the single chips to form a composite chip package. Ball mounting is then performed over the openings, thus connecting the I/O pads at the chip sites to the next level of packaging directly. In another embodiment, the adhesive layer is formed on the wafer side first to form an adwafer, which is then die sawed in CSPs. Then the CSPs with the adhesive already on them are bonded to a substrate. The composite chip package may optionally be encapsulated with a molding material. The CSPs provide integrated and shorter chip connections especially suited for high frequency circuit applications, and can leverage the currently existing test infrastructure.
