    Abstract: The invention relates to a probe needle for testing semiconductor chips, one end of said probe needle being fixed in a holding element and the free end thereof comprising a contact tip. The invention also relates to a method for producing a probe needle for testing semiconductor chips, said method comprising a plurality of treatment steps for forming the probe needle. The aim of the invention is to increase the service life of probe needles. To this end, the probe needle is provided - at least on the surface of the contact tip - with a layer consisting of a chemically inert, electroconductive material which is hard in relation to the material of contact surfaces of the semiconductor chips.

    Abstract: A method of making an integrated circuit includes providing a semiconductor wafer having a first surface and a second surface opposite the first surface, at least one of the first surface and the second surface including a metallization layer deposited onto the surface. The method additionally includes forming a first trench in the semiconductor wafer extending from one of the first surface and the second surface toward an other of the first surface and the second surface. The method further includes sawing a second trench in the other surface until the second trench communicates with the first trench, thus singulating the integrated circuit from the semiconductor wafer.

    Abstract: The invention relates to an ultrathin semiconductor circuit having contact bumps and to a corresponding production method. The semiconductor circuit includes a bump supporting layer having a supporting layer thickness and having a supporting layer opening for uncovering a contact layer element being formed on the surface of a semiconductor circuit. An electrode layer is situated on the surface of the contact layer element within the opening of the bump supporting layer, on which electrode layer is formed a bump metallization for realizing the contact bump. On account of the bump supporting layer, a thickness of the semiconductor circuit can be thinned to well below 300 micrometers, with the wafer reliably being prevented from breaking. Furthermore, the moisture barrier properties of the semiconductor circuit are thereby improved.
