Abstract: PURPOSE:To miniaturize an element and to prevent wire breakdown, by introducing a dislocation line having an intended shape in a desired part of an Si substrate outside an element region, depositing a conducting material along the dislocation line, and forming an element wiring. CONSTITUTION:An Si3N4 mask is provided on the plane (001) of a P type Si substrate. The edge of the mask is aligned with the direction of an intersecting line <110> between a sliding plane (-111), which yields the dislocation, and the plane (001). Then the device is treated in N2 at 1,100 deg.C for 30min. Then a dislocation line having a shape of semi-hexagonal pattern, is formed from the edge of the mask. The mask is removed, and Au is evaporated on the back surface of the substrate 1. The device is treated in H2 at 900 deg.C. Au is deposited along the dislocation line 2. The Au in the vicinity of the dislocation line 2 is preferentially deposited. The surrounding part becomes a clean Si crystal. The dislocation line, where the Au is deposited, is stable at room temperature. When an N<+> electrode 3 is provided, insulation between the substrate 1 and the dislocation (wiring) line 2 can be kept. Thus the miniature wiring is obtained. When the longest side of the dislocation line 2 is made to be 60 deg. dislocation and expanded dislocation is performed, the deposition of Au is accelerated and the resistance of wiring is decreased. The dislocation line is made to reach the back surface by long-time heat treatment and the penetrated wiring can be also obtained.

Filed: 1993-09-28
Abstract: PURPOSE:To improve the picture quality by reducing harmonic distortion of FM audio recording so as to reduce the disturbance with respect to a low frequency conversion chrominance signal. CONSTITUTION:An audio signal is inputted to an FM audio signal recording processing circuit 8, in which L and R channel signals are subject to frequency modulation respectively and the result is added by an adder circuit 9 to obtain an FMA signal.
