Filed: 1991-04-01
Abstract: PURPOSE:To prevent an interferrence to a recording circuit and to make a S/N of differential pair transistors large by providing the transistors between the common connection point of loading resistors and a power source and specifying the connection. CONSTITUTION:This read out circuit 3 is provided with a P channel transistor (Tr) Q5 between loading resistors R1, R2 and a power source 5, a resistor R3 is connected to the common connection point of the gate and the resistors R1 and R2 and the corrector of a Tr Q6 is connected to the gate. When a power source 12 and the base current of the Tr Q6 are set at zero at the time of recording, the side connected to the R1 and R2 is operated as a source and the side connected to a power source 5 is operated as a drain, but since the Tr Q6 is off and the gate of the Tr Q5 is connected to a source via a resistor R3, a current becomes zero between the gate and the source and becomes an off condition by making the Tr Q5 an enhancing type. Thus, a by-pass is not formed for a current generated at a head 1.

IPC: H01L21/66
Filed: 1991-04-01
Abstract: PURPOSE:To easily evaluate outer and inner cracks of a semiconductor device by grinding the surface of the device, then conducting a saturated pressure- cooker test, and measuring the weight before and after the test. CONSTITUTION:The surface of the package of a semiconductor device as a sample is first ground. Then, after the weight is measured, a saturated pressure cooker test is conducted. Thereafter, after the test is finished, the weight is again measured, and presence or absence of an inner crack of the device is determined from the difference of the values of the weight before and after the tests. Thus, since the test is conducted after the surface of the device is ground to reach the inner crack, water easily reaches the crack, moisture due to dew-condensation in the crack is increased to judge presence or absence of the crack.
