Filed: 1990-11-28
Abstract: PURPOSE:To obtain a voltage control oscillator(VCO) which operates stably by forming the rectangular pattern part of an inductance so that the width between the patterns can be five times as long as the width of the pattern. CONSTITUTION:When a layer adhesive used for a multilayer substrate is adhered between the patterns of the rectangular pattern of the inductance formed at an intermediate layer, a capacitor capacity is formed between the patterns, the Z-f characteristic of the inductance is deteriorated, and the VCO having a prescribed characteristic can not be obtained. Then, the width between the rectangular patterns is set to be five times as long as the width of the pattern, and the capacitor capacity due to the adhesion of the layer adhesive is sharply reduced. As the result, the impedance Z(OMEGA) and inductance L(nH) of an inductance L6 are almost flat as respectively indicated by I and J. Thus, the VCO having the stable characteristic can be obtained.

Title: Semiconductor device
Inventor: KONDO YASUO
IPC: G11C29/00
Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To sort a partially defectless article in accordance with the same program as a perfectly moving article (perfectly defectless article) sorting program by providing a redundancy circuit for outputting the same signal as that outputted from a normal output terminal to the defective output terminal of the partially defectless article. SOLUTION: When, for example, only a bus 9 for output terminal does not work normally in a chip (partially defectless article), a switching signal 5 is changed to a low level (enable) from a high level by raising the input potentials of inverters INV1 and INV5 to high levels, lowering the input potential of an inverter INV3 to a low level, and raising the three input potentials of a NAND circuit NAND2 to high levels by disconnecting fuses 1 and 2. Consequently, CMOS bus transistors (MN1 and MP1) are conducted and CMOS bus transistors (MN2 and MP2) are non-conducted and an output bus 10 for output terminal is switched to a normally working output bus 8 for output terminal from the bus 9. Therefore, the same sorting program as that applied to perfectly working articles can be applied to partially defectless articles.
