Title: Method for cleaning device for forming deposited film
Inventor: YAMAMURA MASATERU
IPC: H01L31/08
Filed: 1988-11-08
Abstract: PURPOSE:To maintain the quality of a deposited film on a high level and to uniformly and efficiently remove deposits on the inner wall, etc., of a reaction chamber by using an etching gas prepd. by mixing a gaseous SF6-oxygen compd. mixture with a gas other than SF6. CONSTITUTION:When a deposited film is formed on a substrate in a reaction chamber by a vapor phase process, an Si atom-based film and a silane polycompound are produced on the inside of the chamber. In order to remove the deposits, an etching gas prepd. by mixing a gaseous SF6-oxygen compd. mixture with a gas other than SF6 is used. The molecules of the etching gas are brought into a plasma reaction by applying high frequency energy and the deposits on the inner wall of the reaction chamber are removed by the etching action of the resulting active component. The etching gas other than SF6 may be CF4 or NF3 and is preferably mixed by about 10-80% of the total flow rate of the mixed etching gas. The deposits in the reaction chamber can be efficiently removed in a short time.

Title: Mis transistor
Inventor: KUDO NOBORU
IPC: H01L29/78
Filed: 1985-12-16
Abstract: PURPOSE:To reduce junction capacitance between a drain and a substrate, and to increase the working speed of a transistor, and to improve the performance of an integrated circuit, by forming the drain in the MIS transistor having short channel length in double diffused structure. CONSTITUTION:An impurity diffusion layer 10, which is wider and deeper than a drain 8 and has a conduction type reverse to a substrate 1 and impurity concentration thinner than the substrate 1, is shaped into the drain 8. Consequently, impurity concentration in a region in the substrate being in contact with the drain 8 is thinner substantially. Accordingly, junction capacitance between the drain 8 and the substrate 1 can be reduced, thus improving the performance of an integrated circuit by increasing the working speed of a transistor. The P<-> region 10 can be formed by self-alignment through a method such as an ion implantation method, using a poly Si gate 4 and a field oxide film 2 as masks, thus eliminating the need for a masking process.

Filed: 1986-11-28
Abstract: PURPOSE:To transmit a block jumping request earlier by several machine cycles by holding the information on the read history and the branch instruction of an instruction word positioned at the final word of an instruction buffer. CONSTITUTION:The instruction words are successively read out of an instruction buffer 3. If these words are not equal to the branch instruction, the corresponding bit of a read history register 8 is set and the information on said bit contents is written into a read history table 78 via a line 32. In case of request, a decoding circuit 18 decides whether the instruction words position in a range covering an address shown by a buffer register 12 through buffer 3 or not whether a branch instruction exists or not with reference to the output of the register 8. Then the information showing the permission of a request is sent to a control circuit 20 after a fact is detected that all instruction words existing up to the block end have the read histories with absence of branch instructions.

Title: Japanese syllabary/chinese character converting method
Inventor: TOKUHASHI YOSHIO
IPC: G06F17/22
Filed: 1996-10-25
Abstract: PROBLEM TO BE SOLVED: To validly utilize a dictionary for abbreviation conversion by automatically registering a character string including a variable in the dictionary for abbreviation conversion when a variable is included in a character string in a referred dictionary at the time of operating Japanese syllabary/Chinese character conversion by referring to a standard dictionary or a user dictionary. SOLUTION: At the time of operating Japanese syllabary/Chinese character conversion by referring to a standard dictionary 4 or a user dictionary 5, when a variable is included in a character string in the referred dictionary, the character string including the variable is automatically registered in a dictionary 6 for abbreviation conversion.  That is, at the time of inputting a similar character string whose only one part is different many times, a Chinese character already registered in the dictionary 6 for abbreviation conversion is compared with the Chinese character converted this time at the time of the dictionary for abbreviation conversion registration after the establishment of conversion, and when only one character (the number of characters can be arbitrary) is different, the different part is displaced with a variable, and it is re-registered as one character string including the variable. Thus, a necessary dictionary area is reduced, and as a result, a dictionary capacity is validly utilized.

By forming a bit line of the first wiring material 41 and the second wiring material 42 whose Fermi level is higher than the first wiring material 41, heat is absorbed by the contact surface 43 of them, a transistor constituting a storage cell and minute capacitor 2 are cooled, leak or escape of charges from the minute capacitor 2 is reduced, and supply period of charges (period of refreshing operation) can be prolonged. Thus a dynamic memory element whose electric consumption power is small can be obtained.
