There is provided a probe card in contact with pads formed on a plurality of semiconductor dies on a wafer to test the semiconductor dies. The probe card includes a printed circuit board on which a plurality of pads are formed; a block plate having a plurality of grooves and attached to the printed circuit board; a plurality of sub-probe units equipped with a plurality of probe tips in contact with the pads of the semiconductor dies and detachably coupled to the plurality of grooves; and a plurality of interposer/space transformer units interposed between the sub-probe units and the printed circuit board and configured to electrically connect the probe tips to the pads of the printed circuit board and transform a pitch of the pads formed on the printed circuit to a pitch of the plurality of probe tips.

Probe card and manufacturing method

A method of manufacturing a capacitor for a semiconductor device includes forming a lower electrode, forming a dielectric layer on the lower electrode, forming a first upper electrode on the dielectric layer, adsorbing an organic silicon source onto a surface of the first upper electrode, and forming a second upper electrode on the first upper electrode onto which the organic silicon source is adsorbed. Related devices and fabrication methods are also discussed.

Methods of manufacturing capacitors for semiconductor devices

A method of fabricating a probe tip for use in a scanning probe microscope, includes the steps of: forming a triangular prism provided with a passivation film by patterning a {111} general silicon wafer, the passivation film being deposited on two sidewalls of the triangular prism; etching the silicon wafer to make the triangular prism into a probe tip of a triangular pyramid shape; and removing the passivation film.
