摘要:
A circuit substrate and the method for fabricating a packaging of the circuit substrate are provided. A plurality of electrodes are formed on the surface of the circuit substrate, the electrodes are formed with fork structures over an connection section of the circuit substrate, so that when the circuit substrate expands/contracts due to thermal processes, the probability of alignment with electrodes of an external circuit board is increased by easily detaching the fork structure overlapping an electrode of the external circuit board which is not corresponding to the fork structure of the electrode of the circuit substrate, so as to avoid short circuit. Thus, electrode misalignment due to electrode pitch variation of the traditional circuit substrate as a result of thermal deformation can be effectively eliminated.

A composite bump suitable for disposing on a substrate pad is provided. The composite bump includes a compliant body and an outer conductive layer. The coefficient of thermal expansion (CTE) of the compliant body is between 5 ppm/° C. and 200 ppm/° C. The outer conductive layer covers the compliant body and is electrically connected to the pad. The compliant body can provide a stress buffering effect for a bonding operation. Furthermore, by setting of the CTE of the compliant body within a preferable range, damages caused by thermal stress are reduced while the bonding effect is enhanced.

A method for forming electrically conductive bumps on a semiconductor substrate, or a semiconductor wafer and devices formed by the method are disclosed. In the method, a wafer that has an active surface, a plurality of conductive elements formed on the active surface and a passivation layer insulating the plurality of conductive bumps from each other is first provided. A first metal layer is then sputter deposited on top of the plurality of conductive elements and the passivation layer, followed by stencil printing a plurality of bumps of an insulating material on top of each one of the plurality of conductive elements. The plurality of bumps may be heat treated to a temperature of at least 100° C. for a period of at least 10 minutes for stress relief. A second metal layer is then sputter deposited on top of the plurality of bumps and the first metal layer. The first and the second metal layers are then patterned by a photolithographic process and formed by a wet or dry etching process to remove metal layers in areas in-between the plurality of bumps.

A method for simultaneously forming a flat display panel and bonding to a printed circuit board is disclosed in which a silicon wafer is first supplied and then coated with an alignment layer, a multiplicity of spacers are then mounted to the wafer before it is severed into a multiplicity of dies. A frame seal is then applied to the periphery of the die, while a multiplicity of metal leads is formed on the die for electrical communication with a multiplicity of thin film transistors. A glass plate is then assembled to the silicon substrate by the frame seal, while simultaneously bonded to a printed circuit board in a bonder apparatus under pressure by utilizing a conductive material such as silver paste, an anisotropic conductive film or an isotropic conductive adhesive. The bonding of the printed circuit board to the flat panel display module occurs simultaneously with the formation of interconnections between the printed circuit board and the multiplicity of metal leads on the silicon substrate through a multiplicity of transparent electrodes formed on the glass plate of the flat panel display. The present invention novel structure allows the use of a conventional alignment apparatus such as CCD for optical alignment and a conventional bonder apparatus since a glass substrate is completely exposed and optical transmission can be achieved through the flat panel display module.
