Abstract

Provided is an ohm contact imitation resistor test apparatus and a test method. The method comprises the following steps: (1) ventilating; (2) putting a product to be tested on the base plate of a frame shape support, wherein the test points aim at the metal electrodes and a positioning clamp can be designed according to different products; (3) opening a cylinder switch and pressing downward pressure plates to make the metal electrodes on the pressure plates to fully contact with the product to be tested; (4) reading the resistance value on the ohmmeter; (5) closing the cylinder switch, raising the pressure plates and removing the product tested. The advantages are: (1) the test apparatus helps minimize technology process and save production time; (2) the manufacture process of the test apparatus is simple and the cost of the test apparatus is low; (3) the test apparatus has good stability and easy operation; (4) the test apparatus has a wide application range.

Description

technical field [0001] The invention relates to the technical field of semiconductor resistance material measurement, in particular to a simulated ohmic contact resistance test device and a test method. Background technique [0002] The traditional resistance measurement method of semiconductor resistance materials is to prepare ohmic contact electrodes by metallization at both ends of the material to be tested, and then test the resistance. This process is complicated, the test takes a long time, the test cost is high, and it is not convenient for the test of batch products. Contents of the invention [0003] The purpose of the present invention is to develop a simulation ohmic contact resistance testing device and testing method for directly, accurately, quickly and stably measuring the resistance value of semiconductor resistance materials without the need of ohmic contact electrodes. [0004] The basic principle of the present invention is to press the metal electrode...
