    • Several embodiments of integrated circuit probe card assemblies are disclosed, which extend the mechanical compliance of both MEMS and thin-film fabricated probes, such that these types of spring probe structures can be used to test one or more integrated circuits on a semiconductor wafer. Several embodiments of probe card assemblies, which provide tight signal pad pitch compliance and/or enable high levels of parallel testing in commercial wafer probing equipment, are disclosed. In some preferred embodiments, the probe card assembly structures include separable standard components, which reduce assembly manufacturing cost and manufacturing time. These structures and assemblies enable high speed testing in wafer form. The probes also have built in mechanical protection for both the integrated circuits and the MEMS or thin film fabricated spring tips and probe layout structures on substrates. Interleaved spring probe tip designs are defined which allow multiple probe contacts on very small integrated circuit pads. The shapes of probe tips are preferably defined to control the depth of probe tip penetration between a probe spring and a pad or trace on an integrated circuit device. Improved protective coating techniques for spring probes are also disclosed, offering increased reliability and extended useful service lives for probe card assemblies.
    • 公开了集成电路探针卡组件的几个实施例,其延伸了MEMS和薄膜制造的探针的机械顺应性,使得这些类型的弹簧探针结构可用于测试半导体晶片上的一个或多个集成电路。 公开了在商业晶片探测设备中提供紧密的信号垫间距顺应性和/或实现高水平并行测试的探针卡组件的几个实施例。 在一些优选实施例中,探针卡组件结构包括可分离的标准部件,这降低了组装制造成本和制造时间。 这些结构和组件能够以晶圆形式进行高速测试。 这些探头还内置了集成电路和MEMS或薄膜制造的弹簧尖端和基板上的探针布局结构的机械保护。 定义了交错的弹簧探针尖端设计,允许在非常小的集成电路板上进行多个探针接触。 探针尖端的形状优选地限定为控制探针尖端在探针弹簧和集成电路器件上的焊盘或迹线之间的深度。 还公开了用于弹簧探针的改进的保护涂层技术,为探针卡组件提供增加的可靠性和延长的有用的使用寿命。
