Title: Method of opening fuse line in semiconductor devices
Inventor: NA JONG HUN
IPC: H01L21/82
Filed: 2002-12-23
Abstract: PURPOSE: A method for opening a fuse line of a semiconductor device is provided to prevent an interconnection layer located under an interlayer dielectric from being exposed by forming each fuse line open region in every line. CONSTITUTION: An interconnection layer and an interlayer dielectric(14) are sequentially formed on a semiconductor substrate(10). A fuse line(16) and a metal layer are sequentially formed in a predetermined region of the interlayer dielectric. A passivation layer(20,22) is formed on the resultant structure. A pattern for defining a fuse line open region for opening the upper part of the fuse line only is formed on the passivation layer. The passivation layer and a metal layer are removed by using the pattern for defining the fuse line open region as a mask to open the fuse line.

Title: System for designing visual information to be displayed on monitor unit used in combination with programmable controller
IPC: G05B19/05
Filed: 2000-09-28
Abstract: A system for designing visual information on a monitor unit which enables the use of the monitor unit manufactured at a reduced cost but assures rapid reproduction of the intended visual information. The monitor unit is utilized in combination with a programmable logic controller (PLC) for monitoring a task to be performed by I/O devices managed by the PLC. The monitor unit includes a display, a controller section, and a memory. The system includes an image design tool operating on a personal computer for creating a source display code of the visual information to be reproduced on the display. The image design tool has a conversion means which translates the source display code into a corresponding bitmapped image and exports the bitmapped image to the monitor unit for immediate reproduction of the visual information on the display. Consequently, the monitor unit can be dispensed with a costly component of translating the source image code into the bitmapped image, yet effecting rapid reproduction of the visual information on the display directly from the bitmapped image transferred from the image design tool. <IMAGE>
