Patent number: 8575954Abstract: Based upon a layout of a semiconductor wafer comprising a plurality of integrated circuits at pre-defined locations, each integrated circuit comprising a set of electrical connection pads, a probe chip contactor is established, having a unit standard cell on the probe side of the probe chip to correspond to each of the arranged integrated circuits. The unit standard cell is stepped and repeated for the probe side of the probe chip contactor, to establish a wafer scale standard cell layout. The opposite contact side of the probe chip contactor is connectable to a central structure, e.g. a Z-block or PC board, typically comprising a fixed array of vias with fixed X, Y, and Z locations. The routing of contact side of the probe chip contactor is preferably routed automatically, such as implemented on one or more computers, to provide electrical connections between the substrate through vias and the Z-block through vias.Type: GrantFiled: January 31, 2008Date of Patent: November 5, 2013Assignee: Advantest (Singapore) Pte LtdInventors: Fu Chiung Chong, William R.

Patent number: 7952373Abstract: 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.Type: GrantFiled: October 23, 2006Date of Patent: May 31, 2011Assignee: Verigy (Singapore) Pte.
