Title: Data bus clamp circuit for semiconductor memory
Inventor: MIYAWAKI MASABUMI
IPC: G11C11/409
Filed: 1988-07-12
Abstract: PURPOSE:To always operate a differential amplifier type readout circuit at a high speed by constituting the title circuit of 1st and 2nd discharge circuits which respectively discharge electric charges of complementary data buses for prescribed periods. CONSTITUTION:The data bus clamp circuit is constituted of the 1st discharge circuit composed of N transistors (TR) 61-63 having small mutual conductances and the 2nd discharge circuit composed of N TRs 80-83 having large mutual conductances. Then data buses DB and the inverse of DB are gradually discharged by the 1st discharge circuit while a low-address strobe signal RAS is active. When a row decoder enable signal Yde rises from 'L' to 'H' thereafter, the electric charges of the buses DB and the inverse of DB are quickly discharged by the 2nd discharge circuit and the potential at the buses DB and the inverse of DB drops following the drop of a supply voltage. As a result, the potential and potential difference at and between the buses DB and the inverse of DB are maintained at the optimum values. Therefore, the differential amplifier type readout circuit which reads out the potential and potential difference always operates at the high speed.

Title: Electron beam device
Inventor: ITO AKIO
IPC: H01J37/244
Filed: 1988-07-11
Abstract: PURPOSE:To perform measurement in a large region so far as a high-precision measurement is feasible by arranging so that a first lens may image a secondary electron sample image on this side of a second lens and a focus of the second lens may accord with the secondary electron sample image. CONSTITUTION:Electrons emitted from above an axis of the sample surface 8 at an angle alpha are converged upon one point by a first lens L1 at the secondary electron sample image point SI for being completely collimated by a second lens L2. This is because a focus of the second lens L2 is made to accord with the secondary electron sample image SI. On the other hand, the electrtons emitted from the point distant by gammaS from above the axis go out from the second lens L2 at a slight angle. This angle theta2 is fixed by the magnification M1 and the distance l being able to be minimized to a negligible extent. Thereby, when an analyzing grid is arranged in the rear (the upper part) of the second lens L2, secondary electrons of the sample surface in a wide range can be analyzed with good accuracy thus being able to expand a high-precision voltage measuring region.
