发明名称 Layered microelectronic contact and method for fabricating same
摘要 A microelectronic spring contact for making electrical contact between a device and a mating substrate and method of making the same are disclosed. The spring contact has a compliant pad adhered to a substrate of the device and spaced apart from a terminal of the device. The compliant pad has a base adhered to the substrate, and side surfaces extending away from the substrate and tapering to a smaller end area distal from the substrate. A trace extends from the terminal of the device over the compliant pad to its end area. At least a portion of the compliant pad end area is covered by the trace, and a portion of the trace that is over the compliant pad is supported by the compliant pad. A horizontal microelectronic spring contact and method of making the same are also disclosed. The horizontal spring contact has a rigid trace attached at a first end to a terminal of a substrate. The trace is free from attachment at its second end, and extends from the terminal in a direction substantially parallel to a surface of the substrate to/the second end. At least a distal portion of the trace extending to the second end is spaced apart from the surface of the substrate. The spaced-apart distal portion is flexible in a plane parallel to the substrate.
