Patent JP-S58176938-A (JP)
Title: Fine pattern formation
Inventor: TAMAMURA TOSHIAKI
IPC: G03F7/20
Filed: 1982-04-12
Abstract: PURPOSE:To form a pattern of high ratio of form at a high resolution by means of a thin graft polymer film by a method wherein a graft polymer film pattern is fored on an Si resin layer by using a double layer film constituted of an organic polymer layer in the lower layer and an Si resin layer in the upper layer, as the base material film. CONSTITUTION:The relatively thick organic polymer layer 2 of the film thickness approx. 1mum is coated on a substrate 1, and the relatively thin Si resin layer 3 of approx. 0.1mum is coated thereon. High energy rays 4 are irradiated onto the substrate having the thus obtained double layer film into an arbitrary pattern, then it is placed under the atmosphere of a monomer gas 5 which enables to additionally polymerize without being exposed to the air, and the pattern of the graft polymer film 6 is formed by selectively graft-polymerize the monomer on the irradiated part. Even by using a very thin Si resin layer, since the pattern can be transferred to the relatively thick organic polymer layer, the graft polymer film can be formed thin, and thus not only the resolution can be improved, but also a high sensitivity can be realized.

Filed: 1987-03-13
Abstract: PURPOSE:To make it unnecessary to expose a lower electrode in the atmosphere, eliminate a cleaning process and stabilize junction characteristics and improve the quality, by a method wherein a process in which a bias voltage is applied to a substrate and an insulating film is etched with neutral gas ions to expose the side surfaces of the lower electrode and then a process in which an upper electrode is applied to the insulating film including a junction barrier film are provided.

Title: Ferroelectric memory cell and method for detection and writeof its polarization state
Inventor: PAPU DEII MANIAA
IPC: G11C14/00
Filed: 1994-03-07
Abstract: PURPOSE: To improve the method for detecting the polarized state of ferroelectric capacitor in a memory cell by applying the ferroelectric capacitor with a field cycling from zero through one of upper or lower field point to zero and then measuring variation of polarization. CONSTITUTION: A memory cell 10 stores data in a ferroelectric capacitor 20 and bit lines 24, 25 are coupled with the complementary output of a detection amplifier 30. The capacitor 20 is in one polarization state (A or D) when the stored data is logical 1 (H), and it is in the opposite polarization state when the data is logical 0 (L). At that time, the capacitor 20 is assumed to be in state A. In order to access the cell 10 and detect a stored data, a positive signal is applied to a word line 22 and a reference word line 40. Consequently, a Tr 35 is turned on and a positive voltage across the capacitor 20 is applied from a high bit line 24 to a low plate line 23 and thereby the line 24 goes L. Subsequently, a positive voltage is applied to the lines 23, 24 and the capacitor 20 drops to D state. Variation of polarization is detected at that time.

Abstract: PURPOSE:To make it possible to evaluate the step coverage of an upper conducting film on the periphery of a contact hole in a short time by a method wherein the upper conducting film located on one side of an etching removal boundary line is etched away using such a mask pattern in which the etching removal boundary line passes through the central part of the contact hole. CONSTITUTION:A contact hole 5 is formed and thereafter, an Al conducting film 6 is coated. Then, a resist pattern is formed in such a way that an etching removal boundary line 71 passes through the central part of the contact hole and a UV curing is performed. After that, when an etching is performed by an RIE method, the section of the conducting film coated on the periphery of the hole 5 is exposed. Moreover, after the removal of the resist pattern, a monitor is slanted at a constant angle from a perpendicular to the surface of a wafer to scan in the direction shown by an arrow P and an observation is conducted by an electron microscope. Thereby, the evaluation of the step coverage of the conducting film at a desired contact hole part becomes possible. Accordingly, the step coverage of the conducting part at the desired hole part can be evaluated in a short time.

Filed: 1982-04-09
Abstract: PURPOSE:To make the recording time and recording interval time constant, by providing two buffer memories storing a restored picture signal at every N-line and operating the two buffers alternately. CONSTITUTION:A transmitted compressed picture signal is inputted to a compres sion and expanding circuit 2 via an input terminal 1 and restored intop an original picture signal.

Title: Apparatus for measuring water content rate
Inventor: NODA RYUZO
IPC: G01N27/22
Filed: 1989-03-13
Abstract: PURPOSE:To measure the rate of water content of a material continuously in a short time by detecting the dielectric constant of the material as the electric variable of a transmitting line, and converting the electric variable into the percent of water contents of the material. CONSTITUTION:When the amount of water in the ground is measured, a transmission line 1 is embedded in the ground. The resonant frequency of the line 1 is decreased when the percentage of water content is increased. At this time, the voltage across both ends of a series circuit of the line 1 and reference impedance 2 and the voltage across both ends of the line 1 are measured with a variable frequency oscillator 3. The values are inputted into a CPU 4 through an A/D converter 6. In the CPU 4, the measured results are operated, and the impedance of the line 1 is obtained. After the measurement of the impedance, the frequency at which the impedance becomes the minimum value (the terminating end of the line 1 is opened) or the maximum value (the terminating end of the line 1 is shorted) is obtained. This frequency is the resonant frequency of the line 1. This resonant frequency is converted into the percentage of the water content.
