Patent JP-H04242952-A (JP)
Title: Thin film forming equipment
Inventor: OMI TADAHIRO
IPC: C23C8/10
Filed: 1991-01-01
Abstract: PURPOSE:To prevent deterioration both in contact resistance and in characteristics of dielectric strength by exposing the ground surface of a semiconductor substrate and by avoiding aeration of an exposed surface before a thin conductive film and a thermal oxide film are formed. CONSTITUTION:For example, a semiconductor wafer before a surface film is formed is introduced into an RIE device 2 and irradiated with ions in the surface. This operation makes a wafer cleaned of impurities and a natural oxide film deposited on its surface. Next, the wafer is transferred into an oxidation device 4 through a tunnel 1 having a permanent inflow of N2 gas or air whose hydrogen concentration is kept at less than 10ppb. An SiO2 film is formed on the wafer surface by thermal oxidation in the oxidation device 4. Preparing a MOS transistor whose gate insulating film is an SiO2 on this wafer induces deterioration neither in contact resistance nor in characteristics of dielectric strength.

Title: Simulation method of etching process
Inventor: IKEUCHI HIDETAKA
IPC: H01L21/306
Filed: 1991-01-31
Abstract: PURPOSE:To simulate the etching operation of many layers by a method wherein an etching rate for other substances, to be etched, which have been exposed by deleting a point train is applied to the substances and a point train is moved by an etching rate which is peculiar to each substance. CONSTITUTION:An oxide film 2 is formed on a silicon substrate 1; a nitride film 3 is formed on the oxide film 2. When a developed resist 4 exists on its upper part, a point train 5 is formed around each substance. An etching operation is made to progress clockwise; the intersection P of a point train is detected at each time step. At a stage where the intersection of the point train 5 has been detected, the point train is cut into pieces; a substance to be etched on the lower layer is exposed. Regarding a face (a flag is given as a candidate of a point to be moved to a point train included in the face) which comes into contact with an etching substance, an etching operation is continued at an etching rate which is decided by each substance to be etched and the etching substance.

IPC: H04N21/236
Filed: 1994-02-01
Abstract: PURPOSE: To quickly identify a data file packet of a file that is selected when the preamble of each packet is not completely identified, to minimize the length of each field that is transmitted with each packet, to identify each segment of a selected file and to minimize processing burden to a receiver when a file is repeatedly transmitted. CONSTITUTION: A data file is divided into packets, and a sequence group of packets that constitute a field is identified as a segment. A 1st packet 10 of each segment has a service identification number 12, a block number 14, a segment number 16, segment length information 18 and a prefix including data content. The next packet of a segment has the numbers 12 and 14 and data content. When file data is repeatedly transmitted, it is possible to considerably reduce a receiving processing time or power without changing many segments by including a version number 26 or a toggle bit in a segment prefix. Then unchanging data is ignored by a receiver.

Filed: 1986-01-22
Abstract: PURPOSE:To measure the film thickness of a liquid crystal anchoring layer handily and at a low cost by utilizing the relationship between rotatory power obtained, by measurement and the thickness of liquid crystal and rotatory power of liquid crystal. CONSTITUTION:The height l of spacers 4a and 4b is set in plurality l1-l5 and a plurality of liquid crystal cells having gaps according to respective heights are prepared. Then, normal light is projected into respective liquid crystal cells and a rotatory power meter is used to measure the rotatory power from the incident light L1 and emission light L2. As a result, the relationship between the cell gaps 4l1-l5 and the rotatory power is obtained. The relationship is expressed in the X-Y coordinates (X axis: cell gap and Y axis: rotatory power). Then the cell gap is read out at a point where a straight light connecting dots intersects the X axis, namely, a point where the rotatory power is zero. This value gives the thickness of the anchoring layer.
