CONSTITUTION:A field insulating film 2 is formed so as to surround semiconductor element forming regions 11 and 12 of a silicon substrate 1 and a silicon dioxide film 3 having a thickness of 600Angstrom  is formed over the whole surface by thermal oxidation. A resist film 4 is formed by exposure and development with a mask having an aperture in the first region 11 and the thickness of the film 3 in the first region 11 is reduced to about 200Angstrom  by etching to form a film 5. After the film 4 is removed, a resist film 6 having an aperture in the region 12 is formed. Phosphorus ions are implanted through the film 3 as impurity to control the threshold voltage of the second semiconductor element. After the film 6 is removed, phosphorus ions are implanted as impurity with an acceleration voltage with which the ions are transmitted through the film 5 but not transmitted through the film 3 to control the threshold voltage of the first semiconductor element.

Title: Fault location method
Inventor: OTOGURO HITOMI
IPC: G01R31/08
Filed: 1997-04-23
Abstract: PROBLEM TO BE SOLVED: To specify which of two sections output with location is a true failure section. SOLUTION: Current and voltage data transferred from terminal nodes of a transmission line are taken in and voltage on a node point (a) at the self end of a failure assumed section (k) is used to locate a distance L+x up to a failure point F with impedance operation, so that k-1 and (k) are output as failure sections. Similarly, voltage on a node point (b) at the counterpart end of the failure assumed section (k) is used to locate a distance up to the failure point F with impedance operation, so that k+1 and (k) are output as failure sections. The k-1 and (k) as a result of location at the self end and k+1 and (k) as a result of location at the counterpart end are combined to define a common (k) as a true failure section. If the failure section is within k-1, the location result at the counterpart end is k-1 and k+1, and k-1 is a true failure section.
