Filed: 1993-05-28
Abstract: PURPOSE:To obtain a high-gain, low-current consumption sense amplifier circuit which can secure the saturation area of a PMOS transistor without providing any bias circuit and its driving method. CONSTITUTION:This circuit is constituted of a flip-flop circuit 26. The driving method of the circuit 26 is such that the voltage at the first and second connection points 20 and 22 between a first and second parasitic capacitance 12 and 14 and the circuit 26 are individually changed by operating the circuit 26 in accordance with the voltage signal of a word line 101 and charging and discharging the first parasitic capacitance 12 and, at the same time, discharging and charging the second parasitic capacitance 14. When such a constitution is used, the need of the bias circuit which has been required in the conventional example can be eliminated. Therefore, a sense amplifier circuit which consumes a less amount of current can be obtained. In addition, a high gain can be obtained by driving the flip-flop circuit 26.

IPC: H01J37/26
Filed: 1994-06-10
Abstract: PURPOSE: To accurately specify an object structure by detecting information which correlates with a structure of an object using an interference pattern generated by irradiating a common part of the object with two mutually coherent electron beams. CONSTITUTION: An electron beam 2 from an electron gun 4 enters into a splitting device 8 through an irradiation system 10 and generates two electron beams 20 and 22. These two electron beams intersect and form an interference line pattern. The electron beam irradiates a sample object 24 through an irradiation system 26.

Moreover, a deflecting coil 38 decides the position of an irradiation area of the object 24, and decides a relative position of two irradiation beams 20 and 22. By such a composition a diffraction pattern of the object is expanded and forms an image on a surface 42 or 48 according to a phase-shift between two irradiation beams, giving an accurate information of the object.
