Title: Roll call circuit for memory having redundancy circuit
Inventor: AIZAKI AKANE
IPC: G11C29/00
Filed: 1990-02-26
Abstract: PURPOSE:To prevent the characteristic of the operating source current of a memory deteriorated by providing a switching element capable of passing a current only when a read/write control signal is set at a logic level with less current consumption of the memory. CONSTITUTION:In a readout operation, the inverse of W' goes to an 'H' level, and a transistor Q3 is turned off, therefore, no current flows on a roll call circuit 1, and when the memory not using a redundancy circuit is used, a transistor Q4 is turned off since a signal RE is set at an 'L' level, therefore, no current flows on the roll call circuit 1. Also, in a roll call circuit 2, the inverse of W' goes to the 'L' level in a write operation and a transistor Q7 turned on, and all the transistors Q5-Q8 in the roll call circuit 2 are turned on, therefore, the current flows from a power source to the ground, and the inverse of W' goes to the 'H' level in the readout operation, and the transistor Q7 is turned off, thereby, no current flows on the roll call circuit 2. In such a way, no adverse effect is applied to the characteristic of the operating source current.

Abstract: PURPOSE:To make it possible to perform position alignment between a photoelectric mask and a sample and to prevent the effect of scattered electrons of a substrate, by judging the time of mark detection for detecting a position aligning mark which is formed on a sample. CONSTITUTION:When a power source circuit 21 applies a specified voltage across a photoelectric mask 6 and a sample, photoelectrons from the mask 6 are accelerated and made to scan the vicinity of a position aligning mark. A reflected-electron signal (c) is detected with an intermediate electrode plate 10 and a signal detecting circuit 23. The mark is detected with a control circuit 22. The beam position for pattern scribing is adjusted based on the detected mark. Then, the applied voltage is switched to a voltage lower than the voltage at the time of detection with the circuit 21 based on a control signal (b) from the circuit 22. Then, the photoelectrons are accelerated by said voltage, and the resist on the sample is exposed. Thus, the specified pattern is transferred. In this way, position alignment between the mask and the sample can be performed, and the effect of the scattered electrons from the substrate can be prevented.

IPC: H01L21/60
Filed: 1985-03-11
Abstract: PURPOSE:To prevent occurrence of failure of bonding in the titled device by a method wherein the base metal layer of the surface metal film of the bonding pad to be provided on the resin substrate is formed of an alloy plating layer having a soft property. CONSTITUTION:A Cu wiring pattern (copper layer) 2 is formed on a resin substrate 1 by performing an etching using a glass epoxy substrate 1, for example, as the resin substrate. In case of need, the pattern 2 is formed by coating an electroless Cu plating layer, a nickel-cobalt alloy plating layer (base metal layer) 3 is coated on the Cu wiring pattern 2, and finally, an Au plating layer is coated as a surface layer (surface metal layer) 4. The nickel-cobalt alloy plating layer 3 is also more effective as a layer for diffusion prevention of the Au plating layer, which is the surface metal layer 4, than a nickel plating layer alone. By this way, even when the resin substrate 1 is softened by heating at the time of thermocompression bonding, this bonding pad can be held in a mechanically stable state. As a result, the generation of a failure of bonding can be made to reduce to the utmost.
