Then an electromagnetic induction voltage is generated in the conductor 10, and A/D converter 12 converts it into a digital value and the computer 13 reads it. With attention paid to some phase of an AC magnetic field of the generating source 50, phase matching and sampling are conducted. In other words, the computer 13 reads sequentially voltages induced in the conductor 10, at a certain sampling interval according with the same phase of the alternating current, and measures them for one period. With a rotary stage 51 rotated, subsequently, a computed tomography is applied to the measured detected voltages for each phase of the AC magnetic field and the distribution of the AC magnetic field is restored for each phase.

Title: Manufacture of semiconductor device
Inventor: FUJIWARA HIDEAKI
IPC: H01L29/78
Filed: 1994-09-05
Abstract: PURPOSE: To provide the manufacture of a semiconductor device capable of controlling the depth of junction and the gradient of impurity concentration. CONSTITUTION: An arsenic implantatipn area 6 is made by implanting the ions of arsenic into a substrate 1 from above a silicon oxide film 5, and next a low-concentration n<-> -region 9 as an electric field lightening layer is made by activating the implanted arsenic ions after heat treatment. Since the dispersion of scattered ions of arsenic is increased by the silicon oxide film 5, the distribution of the impurities in the implantation area of the arsenic is in such condition that the peak is low and that the dispersion is large. Accordingly, the profile of the impurity concentration in the n<-> -region 9 scarcely changes from the condition after ion implantation, so the depth of the junction of the n<-> -region 9 and the gradient of the impurity concentration can be controlled merely by changing the condition of ion implantation of arsenic.
