Filed: 1984-04-19
Abstract: PURPOSE:To add and vary functions easily by forming a plurality of integrated circuits, which directly has no connecting relationship with functions that a large scale integrated circuit must have and has broad application, in empty regions in a chip having the large scale integrated circuit. CONSTITUTION:Since a design system in which a large scale integrated circuit is divided ino partial circuits and the partial circuits are stacked in a hierarchic manner is adopted in the large scale integrated circuit and rectangles are often formed as the result of the layout of the partial circuits, wasteful empty regions are generated. Elements 4 for adding functions can be dotted without enlarging the shape of a chip by utilizing the empty regions. Even when only a gate 6'' and a gate 7'' are required, a gate 8'' is fitted previously for the layout of the partial circuits. When the gate 8'' must be inserted between the gate 6'' and the gate 7'' by the alteration of a design, an aluminum wiring section 9a or 9b is varied without changing a diffusion layer 10 and a mask for polysilicon 11 as shown in the layout of the lower figure, thus realizing the addition and change of functions.

Title: Processing circuit for defect detecting signal
Inventor: YAMAMURA TATSUO
IPC: G01N21/94
Filed: 1981-05-28
Abstract: PURPOSE:To detect a size of a defect from a theoretical product output of a first signal, which indicates a period extending from a scanning start of a binary-coded image signal to detection of fall edge and a second signal ranging from an edge of a signal, which is delayed by a full scanning period and is inversed, to completion of a scanning. CONSTITUTION:A shift register 1 is a circuit which delays a binary-coded signal input A by a full scanning period to output it. If an initial rise detecting circuit 3 detects an initial rise edge of a wave-form of the signal intput A, delayed by a full scanning period, it outputs a high-level signal till terminal of a scanning period. A final fall detecting circuit 2 detects a final fall edge (d) of the signal input A to set an amount, being equivalent to a time extending from a start point of a scanning period to the edge (d), in a down counter 4 which outputs a high level till a count zero. Thus, a theoretical product of an inversion output of a signal wave form A, delayed by a full scanning period, and a theoretical product of signal wave-forms B and C are formed in a theoretical product circuit 5, and this permits obtaining of a signal, indicating a size of a defect, in a D.
