Field of the Invention The present invention relates to a contact used in an electrical test of a semiconductor element such as a semiconductor integrated circuit and a method of manufacturing the same. [Prior Art] 平板 平板 A flat semiconductor element such as an uncut integrated circuit formed on a semiconductor wafer or an integrated circuit that has been cut from a semiconductor wafer is electrically tested to confirm whether it is manufactured according to specifications. . In such an electrical test, a plurality of probes respectively pressed against the pad electrodes of the semiconductor element are used, that is, a probe card in which a contact is placed on a substrate such as a wiring board or a probe substrate. The probe card is mounted to the tester in such a manner that the solder tab electrode is electrically connected to the test device, i.e., the circuit of the tester. A contact plate made of such a probe card has a plate-like shape (Patent Document 1), and includes a plate-shaped mounting portion that is attached to the substrate in a state in which the vertical direction is extended from the lower end portion of the mounting portion. a plate-shaped arm portion extending toward one side in the left-right direction, a plate-shaped pedestal projecting downward from the front end portion of the arm portion, and protruding downward from the lower end portion of the pedestal portion and having a needle tip at a lower end of the contact portion A plate-like or columnar contact portion (that is, a solder-to-weld contact portion). In the contact, the mounting portion, the arm portion, and the pedestal portion are formed into a plate-shaped contact sub-body by a conductive metal material. The contact element is mounted on the substrate at the upper end of the mounting portion and supported by the substrate in a cantilever shape. 3, 2009, 999, 2009. A probe card system in which a plurality of the contact elements are arranged on a substrate is attached to a tester. When the probe card is installed in the tester, the tip of the probe is pressed against the electrode of the pad, thereby causing the overdrive force—(4) the contactor, and the contact sub-system is elastically changed in the arm, and scraped off with the tip of the needle. An oxide film on the surface of the electrode is welded The action of scraping off the oxide film on the surface of the electrode is performed separately depending on the respective semiconductor elements to be tested. However, in such a contact, the contact is as described above when the power is excessive (〇Verdrive), and the portion on the arm side is used. In the center, the contact portion is bent and the load is applied to the contact portion. Therefore, the electrode is pressed against the electrode, and cracks and defects are generated at the contact portion, and the batch is opened and the pray is known. In addition, due to the offset of the tip position relative to the electrode of the pad, the tip of the tip is pressed to a portion other than the electrode of the pad, or the end of the electrode of the pad is touched, so that a torsional force acts on the contact, in particular, There are many cases where the contact portion is damaged, so that the contact with the known damage contact is not used, and the county a & μ uses the contact of the first contact, and the last contact portion is broken and cannot be 2) The subject '6 proposes a kind of technology (patent literature, ', ' will be elastically deformed with the arm, and the part of the contact portion that is slid in the electric direction of the pad (that is, the direction of the grinding) is reinforced. People 4 also invented - recorded aunt (Japanese Patent No. 2006-270543), in the above-mentioned torsion reinforcement and grinding position, the contact portion of the contact portion in the direction of the right direction, and the contact type of the type described in Patent Document 1, in the overdrive 200940999 When the overdrive acts on the contact, the complicated force such as cracks, defects, breaks, and twists at the contact portion acts on the contact portion, and thus the technique of the patent document 2 and the proposed technique Even if the technology that can only solve their respective problems is applied to the contact of the patent document (the above-mentioned complicated force acts on the contact portion), the problem unique to the contact cannot be solved. Patent Document 1: WO 2006/075408 A1 Patent Document 2: JP-A-2007-192719 SUMMARY OF THE INVENTION The object of the present invention is to prevent a break or a defect of a contact portion due to repeated application of an overdrive force (〇verdrive) to perform a normal gas test. The contact for electrical test according to the present invention includes: a plate-shaped contact sub-body having a mounting portion extending in the vertical direction, an arm extending from at least one side of the lower end portion of the mounting portion, and a left-right direction, and a pedestal portion protruding from a front end portion of the arm portion; a contact portion from the lower end portion of the pedestal portion to the lower end of the shank portion 1 with a lower end of the contact yoke abutting a tip of the electrode of the semiconductor element, and a reinforcing portion The system is disposed near at least the side of the contact portion and the pedestal portion. The reinforcing portion is formed of a metal material different from the contact sub-body and having the toughness of the contact portion. The reinforcing portion may include a film covering all of the surface regions except the tip of the pedestal to D and the tip. The metal material forming the reinforcing portion may comprise an alloy containing at least two metals 5 200940999 elements. The reinforcing portion may include at least two metal material layers laminated. The method for producing a contact for electrical test of the present invention can be applied to an electric test contactor having a plate-shaped contact sub-body and a contact portion projecting from the contact sub-body and having a tip end as a tip. The manufacturing method comprises the following steps. The first step 'forms at least a first photoresist layer having a second recess which follows the contact portion on the base member, and the sacrificial layer is formed in the first recess by deposition of a suitable material. In the second step, after the first photoresist layer is removed, a second photoresist layer having a recess 2 in the portion of the contact portion adjacent to the contact portion and the contact portion is formed on the base member. And, by depositing a conductive material having a higher affinity than the contact portion, forming a 帛" 甫 quot layer in the first recess and further improving the conductive layer having a hardness higher than that of the first reinforcing layer The deposition of the material is formed in the (4) 2 recess. The third step 'removing the second photoresist layer, forming a third photoresist layer having a third recess in the body of the contact sub-substrate on the base member, and being different from the first reinforcing layer, and The toughness is higher than the deposition of the conductive material of the contact portion, and the contact body is formed in the third recess. In the fourth step, after removing the third photoresist layer, a fourth photoresist layer having a fourth recess in the portion of the contact portion adjacent to the contact portion and the contact portion is formed on the base member. And forming a second reinforcing layer in the fourth recess by depositing a conductive material having a higher affinity than the contact portion and different from the probe body. In the first step of 200940999, the contact member including the i-th reinforcing layer, the contact portion, the contact body, and the second reinforcing layer is separated from the base member. The above manufacturing method allows the deposition of the material to the respective recesses to be formed by at least one selected from the group consisting of electroplating techniques, sputtering techniques, and vapor deposition techniques. If the reinforcing portion is formed of a metal material different from the contact sub-body and having a mobility higher than that of the contact portion, the contact portion may generate a three-dimensional action on the contact member due to the twist ❹ = generated by the rubbing direction. It becomes soft and makes the contact portion less susceptible to damage and breakage. * When the reinforcing port P includes a film covering all the surface areas except the lower end portion of the pedestal portion to the contact portion and the needle ', the contact portion becomes softer than the irregular force, and is less likely to be damaged or broken.

The output signal of the area sensor u is image processed and used to determine the coordinate position of the tip 3〇a relative to the semiconductor component 12 or the tester. In the above manner, a plurality of contact members 14 are disposed on the probe card 16 of the probe substrate, and are mounted on a tester including the chuck top 18, the inspection stage 2, and the area sensor 22. Each of the contacts 14 is pressed against the pad electrode in a state where the probe cartridge 6 is attached to the tester, and the overdrive is applied to the pad electrode 3a. Contact the child. Thereby, the contact 14 is elastically deformed in the f portion 26, and the action of the oxidized film which scrapes off the surface of the electrode with the needle tip 30a by the needle tip to the oxidized amine small pore-forming film on the surface of the pad electrode is determined according to the test. The long-distance main road, the 戎 各 each + conductor element 12 are repeated. However, in the contact portion 14 φ, since the reinforcing portion 40 is made of a metal material different from the contact sub-body and having a toughness higher than that of the contact portion, the contact portion 30, the contact portion 30 acts on the grinding process. The irreversible torsion of the contact is caused by three-dimensional damage and damage. The force becomes softer 'the contact portion 30 is not closed, because the surface area of the reinforcing portion contact portion 30, the four-way coating covers all the surface areas from the lower end portion of the pedestal portion 28 to the removal of the needle tip 30a, since 14 200940999 this contact portion 30 pairs of irregular forces will become softer and less susceptible to damage and break the contact 14. Although the pedestal 28 and the contact portion 3 have a complicated structure, they can also utilize lithography using exposure technology and use. It is produced by deposition techniques of conductive metal materials such as electroplating technology, sputtering technology, and vapor deposition technology. [Embodiment of Manufacturing Method of Contact Member] Hereinafter, a practical example of the manufacturing method of the contact member 14 will be described using Figs. 7 to 8 . 7 to 8 are perspective views showing the contact 14 viewed from the left along the axis 48 of Fig. 6. First, as shown in Fig. 7(A), nickel and copper are sputtered on the surface of the plate-like base member 6A made of tantalum or stainless steel to form a thin peeling layer which facilitates peeling of the contact after manufacture. (not shown). Next, as shown in Fig. 7(B), the photoresist 62 is coated on the base member 6 (actually, the peeling layer) to form a layer. ❿ Next, as shown in FIG. 7(C), the photoresist 62 is exposed in a state of covering the reticle, and then subjected to development processing, wherein the reticle is used to at least resemble the recess 64 of the contact portion 30. Formed on the photoresist 62. Next, as shown in Fig. 7(D), a sacrificial layer 66 having a predetermined thickness dimension is formed in the recess 64 by a deposition technique such as plating, sputtering, vapor deposition or the like. Next, as shown in Fig. 7(E), after the photoresist 62 is removed, the photoresist 68 is applied to the base member 60 and the sacrificial layer 66 to form a layer. Next, as shown in Fig. 7(F), the photoresist 68 is exposed while the photomask is covered with the photoresist 68, and then subjected to development processing. By this recess 7〇 15 200940999 is formed in the pre-resistance 68. As shown in Fig. 8(A), the crank-shaped first reinforcing layer 74' having a shape similar to the shape of the front end portion 72 is formed into a crank shape in the recess 70 by deposition techniques such as electric ore, money, and vapor deposition. The first reinforced layer is formed into a layered shape using the above-described conductive metal material. The deposition technique for forming the first reinforcing layer 74 is in contact with platinum, nickel, or the like. The material used in 卩3G has a more excellent workability and is different from the metal material of the contact sub-body. However, the i-th reinforcing layer 74 may be a metal material layer of two or more layers in which a plurality of metal materials each having a specific number of layers are laminated. ★ Next, as shown in Fig. 8(B), the front end portion 72 is formed on the i-th reinforcing layer 74 in the recess 7 by a deposition technique such as plating, money ore, or vapor deposition. The distal end portion 72 is formed in a crank shape similar to the first reinforcing layer 74 by using a high-hardness conductive metal material such as 姥(10) or 嫣(w). As shown in Fig. 8(B), the recess 70 follows the front end portion 72 of the contact member 14. The distal end portion 72 is a portion 72a where the contact portion 30 is formed, and a portion 72b that forms one portion of the pedestal portion and is integrally connected to the contact portion 30 and joined to the rest of the pedestal portion 28, and corresponds to an arrangement region of one portion of the reinforcing portion 4''. Then, as shown in FIG. 8(C), after the photoresist 68 is removed, the photoresist 74 is applied to the base member 60, the sacrificial layer 66, and the tip end portion 72 to form a layer. As shown in FIG. 8(D), the photoresist 74 is subjected to development processing after exposure of the photomask to the photoresist 74. Thereafter, the recess 76 in the contact sub-body is formed in the photoresist. 74. 200940999 Next, as shown in FIG. 8(E), in accordance with the body portion 8〇 of the contact sub-body, P is formed in the recess 76 by deposition techniques such as electric ore, antimony ore, and steaming, wherein the contact sub-body The portion including the portion 72b of the front end 62 has a function of the pedestal portion 28.
