US 7285966 B2Abstract
Disclosed herein are a probe and a method of making the same, and more particularly to a probe having a minute pitch, with which a probe card corresponding to arrangement of pads formed with a massed shape or other various shapes on a wafer is made, and a method of making the same. The probe having a prescribed thickness and formed in the shape of a flat plate. The probe comprises a body part bent at the middle thereof so that the body part is elastically tensioned or compressed when a tension force or a compression force is applied to the body part at the upper and lower ends thereof, a connection part integrally formed with the lower end of the body part, the connection part being fixed to a substrate, and a tip part integrally formed with the upper end of the body part, the tip part contacting a pad of an element.
This application is a National Stage application under 35 U.S.C. � 371 of and claims the benefit of International Application No. PCT/KR2004/000559 filed on Mar. 16, 2004, which claims priority to Korean Application No. 10-2003-0016634, filed on Mar. 17, 2003, which is hereby incorporated by reference.
The present invention relates to a probe and a method of making the same, and more particularly to a probe having a minute pitch, with which a probe card corresponding to arrangement of pads formed with a dense shape or other various shapes on a wafer is made, and a method of making the same.
Generally, semiconductor integrated circuit devices are tested when manufacturing the devices, after manufacturing the devices, or when packaging the devices, in order to verify whether the devices are manufactured while the whole or partial electric characteristics of the devices exactly correspond to the original design of the devices.
Therefore, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a probe having a minute pitch, with which a probe card corresponding to arrangement of pads formed with a dense shape or other various shapes on a wafer is made, and a method of making the same.
Probes according to preferred embodiments of the present invention are shown in FIGS. 7 a to 7 d. Referring to the left side of FIG. 7 a, a probe 70 is formed in the shape of a bent plate, and is made of metal. The probe 70 has a body part 70 b, which is bent at the middle thereof so that the body part 70 b is elastically compressed and expanded when an external force is applied to the body part 70 b. When a tension force or a compression force is applied to the body part 70 b at the upper and lower ends thereof, the body part 70 b is elastically tensioned or compressed within a prescribed allowable limit. The probe 70 also has a connection part 70 a, which is integrally formed with the lower end of the body part 70 b. The connection part 70 a serves as a supporting beam for supporting the body part 70 b when one end of the body part 70 b is connected to a substrate. The probe 70 further has a tip part 70 c integrally formed with the upper end of the body part 70 b. The tip part 70 c directly contacts a pad of an element to be tested. The bottom of the probe 70, which is seen in the direction X at the left side of FIG. 7 a, is shown at the right side of FIG. 7 a. It can be seen from FIG. 7 a that the tip part 70 c is more extended to the left side than the connection part 70 a. This means that the tip part 70 c is disposed at the outermost side of the probe 70 in the horizontal direction at the left side of FIG. 7 a. The reason why the probe 70 is constructed as described above is that adjacent tip parts can be arranged densely in straight lines by an intersection arrangement of the probes, which will be described later.
As apparent from the above description, the present invention provides a probe having a minute pitch, with which a probe card corresponding to arrangement of pads formed with a dense shape or other various shapes on a wafer is made.
