Title: Method for screening resin sealed semiconductor integrated circuit device
Inventor: MORI SHINICHI
IPC: G01R31/30
Filed: 1987-01-21
Abstract: PURPOSE:To make it possible to screen products having slight defects at an early time, by applying an adequate pressure to a packaged device from the outside, and mechanically increasing the pressure on the surface of a chip with a packaging resin and a filler. CONSTITUTION:In a compressing step, a packaged device 6 is fixed on a stage 10, and a pressure is applied with a pusher 11, or a pressure is applied with a high-pressure atmosphere 12 of a gas or a liquid. In any case, the adequate pressure is applied so that the main body of a chip 1 is not broken with internal strain. The pressure, which is applied on the packaged device 6, amplifies and accelerates the effects of a packaging resin 3 and a filler 4 on a memory cell, a circuit or passivation film 2 and accelerates the progress and the yield of defects, which will occur due to minute flaws and defects present on the surface of the chip 1. Thus the defective products can be effectively screened in a short time.

Title: Normalization circuit
Inventor: SUDA MASATO
IPC: G06K9/32
Filed: 1986-01-24
Abstract: PURPOSE:To make the size of the circuit small, the cost unexpensive and the maintenance easy by providing a counter for performing a counting operation synchronously with the addition in an adder and outputting the counted value as a normalization pattern two-dimensional address and forming them on the same semiconductor chip. CONSTITUTION:The W comparator 31 compares the contents of the W1-W3 with that of the W counter 33 and when the value of the W counter 33 is present within a range of the W1-(W1-W2), 1 is outputted and when it is not present, 0 is outputted. The H comparator 32 compares the contents of H1-H3 and the H counter 34, and outputs 1 when the value of the H counter 34 is present in a range of H1-(H1-H2) and outputs 0 when it is not present. Accordingly, when signals from the comparators 31, 32 are inputted to an AND gate 35, an AND output becomes a mask signal in which a part of a normalization pattern is 1 and a part of a while frame is 0. This mask signal divides the normalization pattern formed by scanning a control pattern into a character part and a white frame part in an external circuit. Thereby, they are integrated on one semiconductor chip, which results in the compact size and the low cost of the circuit.

Filed: 1987-01-26
Abstract: PURPOSE:To improve the resolution of cycle control by applying this cycle control only to one of those main circuit switches which controls each load with the ON/OFF control applied to other switches respectively. CONSTITUTION:A 3rd semiconductor switch 10c performs the ON/OFF control when the control level voltage VIN exceeds about 66% of the maximum control level voltage VMAX. A 2nd semiconductor switch 10b performs the ON/OFF control when the voltage VIN exceeds about 33% of the voltage VMAX. While a 1st semiconductor switch 10a gives the cycle control to the electric power of about 0-33%, 33-66% and 66-100% of the voltage VMAX in response to the rate of the VIN against the VMAX. As a result, the resolution of the cycle control is cut down to 1/3 compared with a case where the cycle control is applied to a full range of the control power.
