IPC: H01L21/66
Filed: 1979-06-01
Abstract: PURPOSE:To preferably measure the depth of a shallow junction by moving a probe wound with  coil at a portion where an impurity introduction layer is partly removed on a substrate exposed from the layer when measuring the depth of the junction of the layer and obtaining the depth of the junction from the variation in the inductance of the coil. CONSTITUTION:An N<+> type layer 2 is diffused in a P type is substrate 1. When the depth of the junction is measured, the layer 2 is first coated with wax or resist mask 3, and etched with a solution containing 1:5:40 in volume ratio of HF:HNO3: CH3COOH. Since the interface between the layer 2 and the substrate 1 is remarkably decelerated at its etching rate at this time, the etching process is stopped with this phenomenon as a reference. Thereafter, the mask 3 is removed, a magnetic probe 4 hung via a spring 6 is slided on the surface of the exposed substrate 1 from the layer 2 retained with the mask 3 removed, and the variation in the inductance of the coil 5 surrounding the probe 4 is measured by a step measuring unit 7.
