Abstract: <P>PROBLEM TO BE SOLVED: To provide a photomask which has an OPC (optical proximity correction) pattern and which can deal with scale down of the photomask pattern and does not generate an unnecessary transfer pattern on a wafer and to provide data for the photomask for this purpose.  <P>SOLUTION: The pattern on the wafer corresponding to the data for the photomask is obtained by: using the design data corresponding to the shape of the pattern on the desired wafer or the first correction data obtained by correcting the design data as the original data for the photomask to be processed; and performing simulation or actual manufacture relating thereto. Further, a series of processing is repeated which consists of: the differential pattern acquisition processing to determine the differential pattern which is the difference between the pattern of the design data and the pattern on the wafer; and the correction processing to form the fresh data for the photomask by correcting the same so as to make the differential pattern smaller in succession thereto. The finally obtained data for the photomask is adopted as the data for the photomask having the optical proximity correction pattern after the correction. The correction processing newly obtains the data for the photomask by subjecting the data for the photomask to distributed correction processing by distributing the patterns of the sizes and minute intervals which cannot be resolved by the exposure wavelength on the wafer during the transfer exposure to the wafer.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

Title: Fuse of semiconductor element and its manufacturing method
Inventor: SUN HO-WON
IPC: H01L21/82
Filed: 2003-01-20
Abstract: <P>PROBLEM TO BE SOLVED: To provide a fuse and its forming method for obtaining fine-pitch fuses which are free of damages to adjacent fuses when a selected fuse is irradiated with laser light to be blown.  <P>SOLUTION: While an upper wire connected to a lower wire used as a fuse is patterned, a groove is formed at a position of the lower wire as a laser target spot for fuse blowing. Consequently, a wire breaking capacity, i.e., a part which is irradiated with the laser light can be made extremely small, so that wire breaking is facilitated to increase a rate of success of wire breaking even when the fuse is irradiated with laser light of small energy in a short time. Therefore, excessive stress is prevented from being applied to a fuse which is adjacent to a fuse to be blown, so that the adjacent fuse is not damaged and fuses can be packed below a specified pitch, thereby increasing fuse density (the number of fuses per unit area).  <P>COPYRIGHT: (C)2003,JPO
