Abstract: PURPOSE:To reduce the number of working steps and raise accuracy and reliability, by printing a first wiring layer on a substrate, baking the first wiring layer, printing a resistor, a dielectric substance and a second wiring layer, baking the resistor, the dielectric substance and the second wiring layer simultaneously and coating the resistor and the second wiring layer with the same crystallized glass of low melting point. CONSTITUTION:A paste of Ag-Pd conductor or the like is printed on a substrate 1 of alumina or the like and baked so that the first wiring layer conductor 2 is provided. A resistor paste 4 of RuO2 or the like is then printed. A paste of Ag-Pd conductor is printed in succession to crystalline glass pastes 3'', 3'. The resistor paste 4, the glass pastes 3'', 3' and the paste of Ag-Pd conductor are simultaneously baked so that a dielectric substance 3, a resistor 4 and the second wiring layer conductor 2' are provided. A paste of glass of low melting point is printed to coat the resistor 4 and the conductor 2' and baked so that a glass coating 5 is provided. As a result, the number of times of baking is reduced, the accuracy of resistance is improved,  and the reliability of humidity-proof property is raised by the glass coating.

Title: Semiconductor memory device
Inventor: TOMISATO MASAHIRO
IPC: G11C29/04
Filed: 1986-01-29
Abstract: PURPOSE:To easily decide the number of redundant circuits which have been used, by cutting the fuses of the number being equal to the number of the redundant circuits which have been used, and applying a test signal of the potential being negative or positive to the ground potential to an electrode being its external input signal terminal at the time of an IF test. CONSTITUTION:In a semiconductor memory device provided with (n) (n>=2) pieces of redundant circuits for replacing a defective bit of a memory chip, in case (m) pieces (0<=m<=n) of redundant circuits are used, fuses L1-Lm of a source side extending from an NMOS transistor Q1 to an NMOS transistor Qm are cut successively, electrically or by using a laser light. In this state, at the time of an IF test, in case a voltage signal being negative relatively against a ground potential (Vss) of a Vss wiring 4 has been applied to an electrode 1, a current flows out to the electrode 1 from the Vss wiring 4 through NMOS transistors Qm+1-Qn in which the fuse of the source side is not cut. In this way, from this current value, the number of redundant circuits which have been used can be discriminated.

Abstract: PURPOSE: To reduce the scattering of an MOS capacitance, by making the diameter of a circular metal film provided on the opening of an insulating film on the surface of a substrate, larger than that of a hemispherical metal electrode in bidimensional directions.  
     CONSTITUTION: An SiO 2  insulating film 12 is coated on the semiconductor substrate 11 of a Schottky barrier diode or the like and provided with an opening. A circular multilayer metal film (Mo-Ti-Au) 13 with a diameter of 130μm or the like is provided on the opening and the film 12 around the opening. An almost hemispherical silver electrode 14 is provided on the metal film 13 by selective plating. When the diameter of the silver electrode 14 in bidimensional directions is designed to be 100μm, the diameter of the silver electrode becomes 90∼125μm including deformation due to the pressural contact of an electrode probe and the scattering in the plating process. Since the diameter of the metal film 13 is 127∼133μm, the scattering of an MOS capacitance depends on that of the metal film 13. This results in reducing the scattering of the MOS capacitance in comparison with a conventional case.
