Abstract: PURPOSE:To make it possible to form an upper wiring layer with high reliability by a method wherein after the formation of a metal plug, an anti-oxidation film formed on a layer insulating film is shaped in such a way that it is formed with an excellent coverage. CONSTITUTION:A lower wiring layer 12 consisting of a diffused layer and an interlayer insulating film 16 are formed in and on a semiconductor substrate 10 and an anti-oxidation film 22 is formed on the film 16. An opening part 18 is formed by dry etching and an adhesive layer 20 is made to deposit on the film 22 and in the opening part 18. After that, a tungsten layer 24 is formed and the layer 24 is etched back to form a metal plug 26. Then, the layer 20 on the film 22 is etched away and the layer 20 is left only on the sidewall of the opening part 18. After the plug 26 is formed in the opening part 18, a part 22A, which is adjacent to the opening part 18, of the film 22 is shaped by a horizontal return method. Thereby, the reliability of a process at the time of formation of an upper wiring layer is improved and the reliability of the connection between the metal plug and the upper wiring layer can be improved.

Title: Signal processing system and computer readable recording medium recording signal processing program
Inventor: KANAZAWA MASAYA
IPC: G06F7/76
Filed: 1997-12-24
Abstract: PROBLEM TO BE SOLVED: To provide a signal processing system that can accelerate the processing speed and keep it constant even when adding data with different floating point positions, and a recording medium for recording signal processing program. SOLUTION: When performing an arithmetical shift processing with saturation operation, the number of shifts is judged (S101) and multiplication with a number to be shifted is performed while taking the exponent of '2' of that shift number (S103). After the above operation, a code and overflow are discriminated while referring to the upper half contents of the arithmetic result (S104) and saturation operation is performed (S106 and S107). Thus, since shift processing can be completed only with one time of multiplication, the processing speed can be made stable and accelerated.

Title: Shutter driving mechanism used as lens driving mechanism
Inventor: OZEKI YOSHIYUKI
IPC: G03B9/08
Filed: 1992-12-18
Abstract: PURPOSE:To make a stepping motor used both as a driving source for a lens and for a shutter, and to shorten a time lag in a mechanism capable of performing lens driving by normal rotating operation and shutter driving by reverse rotating operation. CONSTITUTION:A switch 28a works on the first step of a shutter button, and a switch 28b works on the second step. A driving member 2 normally rotates as the switch 28a works, and a lens driving member 5 normally rotates in accordance with the member 2. After the member 2 reversely rotates, a member 3 stops at a focusing position by being locked by a locking lever 6. When the switch 28b works, a shutter blade performs opening and closing work by the series of reverse rotation of the driving member 2; however, the time lag occurs a little from a time when the blade is released to be opened to the time when a pin-hole is formed. When the switch 28b does not work and the switch 28a stops working, the driving member 2 finishes performing reverse rotation work in the time lag, so that the member 2 returns to an initial position without performing real opening. Consequently, sequence can be progressed to the time just before the shutter works, so that the time lag after the switch 28b works can be decreased by the work of the switch 28a.
