Title: Laser trimming method
Inventor: KOWASE YASUAKI
IPC: H01L27/01
Filed: 1987-05-27
Abstract: PURPOSE:To improve conditions in which laser beams are applied, and to enhance the efficiency of cutting by forming a lower-layer metallic film to a section, to which a metallic film pattern to be trimmed is shaped, while forming the metallic pattern to be trimmed onto the lower-layer metallic film through an inter-layer insulating film. CONSTITUTION:A wiring 5 consisting of second layer Al is irradiated with laser beams within a range shown in the figure A, and trimmed. L represents a section trimmed by laser beams. Since a first layer Al film (a dummy film) 3 is shaped previously just under the trimming region A, a recessed section is buried and a foundation SiO2 film to the first layer Al film is to a certain extent flattened even when there are irregularities in the foundation SiO2 film, the second layer Al wiring formed onto the foundation SiO2 film through a thick inter-layer film 4 has uniform film thickness and a flat surface, and the title laser trimming method is extremely effective to laser beams having the different efficiency of cutting by the flatness of a film surface and film thickness.

Title: Process control method
Inventor: MAEDA HIROMOTO
IPC: G06F3/048
Filed: 1993-05-31
Abstract: PURPOSE:To provide the process control method which can minimize the loss of data even if a process in operation runs away. CONSTITUTION:If the process A runs away, a system program 11 activates a process B according to a user's indication. The process B recognizes that the process which runs away is the process A on the basis of a process information control table 12 that the system program 11 controls and the selection indication from the user. Then the process B sends a request to stop the process A to the system program 11, which generates an interruption to the process A. The interrupted process A saves data which are being processed by prescribed interruption processing. Consequently, even if a process in operation runs away, the loss of data can be minimized.
