Title: Capacitor of semiconductor device
Inventor: KUROMARU YOSHIMITSU
IPC: H01L27/04
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To reduce the parasitic capacitance under a lower electrode of an MIM capacitor without forming a large step by forming latticed trenches in plan view in a region of a semiconductor overlapping with the lower electrode and filling an insulating material into the trenches. SOLUTION: A capacitor 9 of a semiconductor device has a lower electrode 10 deposited on a semiconductor substrate 1 via an insulator film. A latticed insulating layer 24 is formed in a region of the semiconductor substrate 1 overlapping with the lower electrode 10. Further, the latticed insulating layer 24 has a latticed cross-section in plan view and is formed by filling an insulating material 24b into trenches 24a formed through an LOX 23. Thus, even if the LOX 23 is not formed thick, the latticed insulating layer 24 keeps the substrate 1 surface opposite to the lower electrode 10 in that part farther therefrom. Therefore, a parasitic capacitance can be suppressed by substantially increasing the distance between the lower electrode 10 of the capacitor 9 and the opposite substrate 1.

IPC: G01R27/28
Filed: 1984-03-15
Abstract: PURPOSE:To measure a coefficient of AM/PM conversion with high precision through simple constitution and simple operation by using a composite signal of three continuous waves (CW) in specific relation. CONSTITUTION:Signals of frequencies f1, f1+fm+DELTAf, and f1-fm+DELTAf are generated by CW signal generators 1-3 and synthesized by a synthesizer 4. Then, f1>>fm>>DELTAf and electric power of the generators 2 and 3 are equal to each other and 1/120 time as large as that of the generator 1; and a carrier of frequency f1 is AM-modulated and PM-modulated with a sine wave of frequency fm and the composite signal varies in opposite-phase relation at a 1/2(2DELTAf) period from a modulation index of zero to a maximum value. Therefore, the output signal of a body 5 to be measured which is supplied with the composite signal is modulated to measure its electric power Pam by a power measuring instrument 10, and the output electric power Ppm of a square-low detector 7 supplied with the composite signal is measured by an electric power measuring instrument 11 to calculate the square mean of the ratio of the Pam and Ppm. Thus, the AM/PM conversion coefficient is measured with high precision through the simple constitution and easy operation which eliminates the need for calibration, etc., by ratio calculation.

Filed: 1983-03-23
Abstract: PURPOSE:To obtain a device with high sensitivity and high resolution by providing a timing electrode passing ions to an incident hole only during a necessary time width and also constituting a diverging/focusing means as a focus lens for focusing ions. CONSTITUTION:During a necessary time width when the potential of each of three electrodes of a timing electrode B1 becomes an equal potential V0, focused ions enter a flight analysis stage C through an incident hole B with the ion orbit not being bent, follow an orbit repeating divergence and focusing by lenses C1, C2, go out through an outgoing hole D, and are detected by an ion detector E. Furthermore, a deflecting potential V2 deflecting ions is applied to the central electrode of the timing electrode B1 during the time except for the necessary time width for detecting ions, thus the orbit of ions is bent, and ions can not fly up to the ion detector E. A signal 8 detected by the ion detector E and amplified by an amplifier 5 is displayed on an oscilloscope 6 together with a timing pulse signal 9 from a timing pulse generator 7, and the ion flight time from the incident hole B to the ion detector E can be observed.
