Definitions
- the present invention relates to an electrical connection technology for electronic components, and more specifically, a microcontact for contacting an electrode of a semiconductor device typified by LSI for electrical conduction and such contact.
- the present invention relates to a contact member used for a child.
- semiconductor devices such as LSIs mounted on electronic devices are also required to be high performance and small. Therefore, in order to integrate more circuits in a smaller volume, the semiconductor device needs to reduce the wiring pattern and reduce the thickness of the wafer.
- the contactors for LSI testing are classified according to the contactors used: 1) contactor using a needle method, 2) contactor using a spring probe as a contactor, 3) contactor using a membrane probe as a contactor, 4) It is classified into 4 types of contactors using anisotropic conductive rubber as contacts.
- Each needle (needle formed of tungsten wire or the like) is formed on the contactor substrate so that it matches the terminal position of the LSI to be tested.
- l_a) Cantilever method It is configured such that the needle extends in an inclined state from above with respect to the electrode of the semiconductor device.
- the probe pin has a configuration in which a spring is disposed between the contact portion with the terminal of the semiconductor device, the contact portion with the substrate, and the contact portion. Due to the elasticity of the springs between the contact parts, the contact parts are pressed against the terminals of the semiconductor device and the test substrate to obtain electrical contact.
- the membrane probe is formed as a film-like circuit board having metal protrusions as contact electrodes for the stylus.
- Anisotropic conductive rubber is formed by using rubber as an insulating member and incorporating a material (such as a metal wire) that conducts only in the thickness direction.
- the contact resistance is the sum of the film resistance, the concentrated resistance, and the specific resistance of the contact.
- the reason why contact resistance is reduced by pressurization is that concentration resistance can be reduced.
- FIG. 2 is a schematic diagram showing a state in which the needle contact 6 is brought into contact with the test terminal 4.
- the terminal surface 4a has irregularities. Department only. Therefore, force and concentration resistance at the contact area are large. The sum of this concentrated resistance and the film resistance due to the coating on the terminal surface and the contact surface is the contact resistance. Therefore, the contact resistance increases as the concentrated resistance increases. For this reason, a large pressure is applied between the two to increase the contact area between the contactor and the electronic component, thereby reducing the concentrated resistance, thereby reducing the contact resistance.
- Patent Document 1 As a contact method other than the contactor described above, in Patent Document 1 below, a silicon processing technique is used on a silicon substrate, a hole for a contact electrode is generated, and the hole is formed in the hole.
