Abstract
A method of manufacturing a probe card and a probe card manufactured using the same are disclosed. The method is configured to be capable of collectively attaching probes to a wiring board provided with a connection pad to which the probes are attached.
Claims9
A method of manufacturing a probe card, the method comprising:
- forming a temporary layer on a surface of a base substrate, forming a masking material layer on a surface of the temporary layer and patterning the masking material layer to form an open area, filling the open area with a conductive material, and removing the masking material layer excluding the conductive material by an etching process;
- manufacturing a multilayer wiring board configured to have an anodic oxide film wiring board which is provided with a plurality of vertical wiring portions and horizontal wiring portions inside and made of an anodic oxide film material;
- placing the base substrate, to which the conductive material is attached, above a probe connection pad of the multilayer wiring board to bond one end of the conductive material to the probe connection pad;
- and
- removing the temporary layer of the base substrate through an etching process using an etchant to separate the other end of the conductive material from the base substrate.
