    Abstract: A probe head for a testing apparatus integrated on a semiconductor wafer is disclosed having a first plurality of contact probes having a first transversal diameter, a second plurality of micro contact probes having a second transversal diameter, smaller than the first transversal diameter, and a flexible membrane having conductive tracks for connecting a first plurality contact probe with a corresponding second plurality micro contact probe. The second plurality contact probes are arranged between the testing apparatus and the flexible membrane, and the second plurality micro contact probes are arranged between the flexible membrane and a semiconductor wafer. The second plurality micro contact probes are configured to abut onto contact pads of a device under test integrated in the semiconductor wafer, with each first plurality contact probe being in contact with a corresponding second plurality micro contact probe through a conductive track of the flexible membrane to connect the device under test with the testing apparatus.

    Abstract: Flexible film electrical-test substrates with at least one conductive contact post for integrated circuit (IC) bump(s) electrical testing, and related methods and testing apparatuses are disclosed. The backside structure of an electrical-test substrate comprises a flexible dielectric film structure. One or more fine-pitched conductive coupling posts are formed on conductive pads disposed on a front side of the flexible dielectric film structure through a fabrication process. A first pitch of the conductive coupling post(s) in the flexible dielectric film structure is provided to be the same or substantially the same as a second pitch of one or more bumps in an IC, such as die or interposer (e.g., forty (40) micrometers (μm) or less). This allows the conductive coupling post(s) to be placed into mechanical contact with at least one bump of the IC, point-by-point, during an electrical test to electrically testing of the IC.
