摘要:
Differential signals are supplied to gates of first and second transistors. One end and a gate of a third transistor are connected to a signal output node. One end and a gate of a fourth transistor are connected to the other end of the second transistor. A fifth transistor is connected between a power source and the other end of the third transistor. A sixth transistor is connected between a power source and the other end of the fourth transistor. A seventh transistor is inserted between the power source and the signal output node. An eighth transistor is inserted between the power source and the common connection node of the second and fourth transistor, and a gate of the eighth transistor is connected to the gate of the sixth transistor.
摘要:
In a method for setting appropriate initial-failure screening conditions when mass-producing semiconductor devices of multiple types, devices of each type being manufactured in a small number, the step of subjecting products of every type to an acceleration test is excluded, and instead, the failure ratio on the market of semiconductor devices of each type is estimated using a testing semiconductor device. Specifically, {circle around (1)} first, all types of semiconductor devices to be developed and mass-produced are classified into several groups. {circle around (2)} A test semiconductor device is developed which has the same number of elements, the same gate area, the same multi-layer wiring length and the same number of contact holes as the average number of elements, the average gate area, the average wiring length and the average number of contact holes of the semiconductor devices included in one of the type groups, respectively. The testing semiconductor device has main features (design rules, MOSFET structure, wiring structure, etc.) common to the types included in its corresponding type group, and a failed portion thereof, if any, can be easily detected by an analysis using a tester.

摘要:
A semiconductor integrated circuit device includes a semiconductor integrated circuit formed in a semiconductor chip, and a switching element that is formed in the semiconductor chip and has a current path whose one end and the other end are both connected to the semiconductor integrated circuit. The switching element receives a control signal produced by a control circuit and causes a current to flow from the one end to the other end of the current path by a bipolar operation. The semiconductor integrated circuit device further includes the control circuit that is formed in the semiconductor chip and configured to control a conductive/non-conductive state of the current path of the switching element.
