Title: Flattening using etchback
Inventor: HIJIKATA ISAMU
IPC: H01L21/302
Filed: 1989-11-17
Abstract: PURPOSE:To make it possible to perform an etching of a photoresist and an etching of an SiO2 film in a state that an etching rate of the photoresist and an etching rate of the SiO2 film coincide correctly with each other by a method wherein the mixed gas containing CF4 gas and SF6 gas is used as reaction gas and moreover, the ratio SF6/(SF6+CF4) of the SF6 gas is specified. CONSTITUTION:The mixed gas containing CF4 gas and SF6 gas is used as reaction gas for etchback use and moreover, the ratio SF6/(SF6+CF4) of the SF6 gas in this mixed gas is set in a ratio of 10 to 80%. When an etching of a photoresist and an etching of an SiO2 film are simultaneously performed using the mixed gas produced by adding the SF6 gas or NF3 gas to the CF4 gas in a specified ratio in such a way, a selection ratio confined to 0.9 to 1.1 or thereabouts without being affected so much by the density of a pattern. Thereby, an etching rate of the photoresist and an etching rate of the SiO2 film become equal to each other and the photoresist film is never etched up in an uneven thickness.

Title: Display device
Inventor: SAKAMOTO YASUTAKA
IPC: G09F9/313
Filed: 1989-11-20
Abstract: PURPOSE:To enable the plural color developments within the same light emitting body and to provide the color development patterns having a wide variety by using a high-frequency and high electric field exciting means. CONSTITUTION:This device has the discharge light emitting body 16 and the high-fre quency and high electric field exciting means 15 which applies electric fields having desired potential gradient characteristics to the light emitting body to cause the light emitting body to develop plural colors in arbitrary patterns. For example, a space region 16b (high-voltage side) in proximity to dielectrics 15 for leading out the electric field shows the color development to the blue intrinsic to argon and a space region 16b enclosing the region 16a of the blue color development shows the red or orange color development intrinsic to neon when a gaseous mixture composed of the neon and argon is sealed into the light emitting body 16 and is excited to emit light. These colors are distinctly separated from each other. The volumetric ratio of the mutual light emission can be changed by changing the mixing ratio of the gaseous neon and the gaseous argon. The formation of the patterns having a wide variety is thus pos sible. The displaying of the plural color developments and intricate color developing shapes is enabled in this way by the single gas-sealed light emitting body.

IPC: A61B8/00
Filed: 1997-10-17
Abstract: PROBLEM TO BE SOLVED: To easily determined an optimum start location for a volume rendering process for an ultrasonograph by using a depth information. SOLUTION: A volume rendering system from a plurality of image data, a noise cut level setting unit 10 which determines a signal process start location by the volume rendering system is installed in this ultrasonograph which produces a three-dimensional imaging of the surface of a diagnosis objective region. Since the tilt of a noise cut straight line and a noise cut level can be freely changed, an optimum start location to perform the volume rendering signal process, can be easily found by using a depth information. Also, by changing a value of a RAM for data convertion in a post-process processing unit 6, conforming to a set value of the noise cut level setting unit 10, the three- dimensional image data can be easily converted and displayed.  By using the depth information which has been lost in the three-dimensional display of a conventional system, the surface image of a diagnosis objective region at an optional depth can be easily obtained.
