Title: Multilayer wiring structure and manufacturing method therefor
Inventor: MATSUMOTO SUSUMU
IPC: H01L21/28
Filed: 1999-11-18
Abstract: PROBLEM TO BE SOLVED: To provide a multilayer wiring structure and its manufacturing method which improves the electromigration resistance and the stress migration resistance, at the same time. SOLUTION: An AlCu film 103C is reacted with a Ti film of 0-15 nm thick, to form an Al3Ti layer 103D on the interface of the AlCu film and a TiN film which suppresses the interface diffusion, reduces tensile stress caused at formation of the Al3Ti layer, and improves EM resistance. For forming an FSG film 104A using the HDP-CVD method thereafter, an inert gas is flowed on the wefer backside to cool the wafer down to a wafer temperature of 450 deg.C or lower, thereby reducing the residual tensile stress of the AlCu film, due to the thermal expansion coefficient difference between FSG and AlCu and improving the SM resistance and the EM region, and an SiON film is provided on the FSG film to block free F in the FSG film from diffusing upwardly to prevent upper layer wirings from stripping.

Title: Angular velocity sensor
Inventor: KOBAYASHI YASUNOBU
IPC: G01C19/5628
Filed: 1998-11-19
Abstract: PROBLEM TO BE SOLVED: To reduce transmission of vibration from the outside to a detection electrode vibrating body so as to prevent deterioration in an output characteristic by fixing a terminal on a base into a hole in a circuit board with a clearance arranged between the base and the circuit base board. SOLUTION: When a tuning fork is turned, an electric charge generated in a detection electrode 28 by a Coriolis force generated in a detection electrode vibrating body 23 is fed to an electronic component 36 in a circuit board 35. This output voltage is processed by a computer, and an angular velocity is detected. When vibration is applied to the circuit board 35 from the outside, the vibration from the outside is damped because a terminal 33 in a base 30 is mounted in a hole 37 in the circuit board 35 for fixing the terminal 33 and the hole 37 while a clearance 38 is arranged between the base 30 and the circuit board 35. That is, the circuit board 35 and the base 30 are fixed only via the thin terminal 33, so that vibration from the outside is hardly transmitted to the detection electrode vibrating body 34.  Consequently, deterioration in an output characteristic of an angular velocity sensor due to generation of electric charge can be prevented.

Title: Program runaway detecting method
Inventor: MIYAO TAKESHI
IPC: G06F11/30
Filed: 1988-12-28
Abstract: PURPOSE:To detect a program runaway even when an area being adjacent to a stack area is used for an arbitrary purpose by storing a boundary address of the stack area in a storage means and executing a decision of a stack pointer. CONSTITUTION:When the system rises, a boundary address of a smaller address of a stack area 102 is stored in a register 104, and comparison of a stack pointer 105 and the boundary address is executed whenever one instruction is executed. When a program runs away, and the pointer 105 overflows the stack area 102, the pointer 105 comes to point to a data area 103, and its value becomes smaller than the boundary address. In this case, it is decided that the program runs away, and the program is stopped immediately. In such a way, since it is unnecessary to provide a program runaway detecting area being adjacent to the stack area, its area can be used for an arbitrary purpose, and a main memory can be utilized efficiently.
