Abstract
A method is provided for shaping tips of lithographically-produced probe elements configured for use in a probe card to establish electrical communication with a contact of a semiconductor device to be tested. The method includes (a) lithographically producing a plurality of probe elements and (b) using a subtractive process, such as laser ablation or micro-electro-discharge machining, to remove material from each tip of the plurality of probe elements to form each tip into a shape well adapted to penetrate a contaminant oxide layer.
