1 Scope

This procedure is applicable to four-probe resistivity testers with a contact range of 10-3 Ω·cm to 103 Ω·cm. First verification, subsequent verification and in-use inspection. For some versatile four-probe resistivity testers or only for measurement Block resistance four probe testers are also suitable. The sheet resistance is measured from 10-2 Ω/□ to 104 Ω/□. This procedure does not apply to the verification of two-probe, three-probe, six-probe and square four-probe resistivity testers.

2 Overview

The four-probe resistivity tester (hereinafter referred to as the resistivity tester) is used to measure semiconductor materials and process silicon. The resistivity of the sheet, or the diffusion layer and the epitaxial layer, and the measuring instrument for the sheet resistance of the insulating substrate coating layer. It is mainly The electrical part and the probe are composed of parts. The automatic tester also includes a computer and an interface, etc., and the electrical part is generally Including adjustable steady current source, A/D converter, digital display, reversing switch and other instruments and components. Probe part general package The probe fixture, the probe and the sample stage are shown in Fig. 1 and Fig. 2.
