Pattern matching seems to be promising technique to the mask industry. It can be used for many applications such as hot spot detection of post-OPC data, search of AIMS reference location or CDSEM measurement point extraction. In particular, fuzzy pat

Since the layout patterns on photomasks have been getting more and more complicated by OPC/RET processes, the mask patterns need to go through the verification to check the mask manufacturability even though the layout is 'DRC clean'. This verificati

In order to go through the transition term from GDSII to OASIS successfully, the aid of the verification tools between OASIS and GDSII is necessary. In general, we have two methods of OASIS file verification. One is a hierarchical method that checks

The OASIS (Open Artwork System Interchange Standard) format is a new standard format for describing LSI layout data and it has begun to be used for photomask data. One of the greatest features of OASIS format is its conciseness of expressing pattern

OASIS format has begun to be accepted in the field of mask data processing gradually. Major EDA venders have announced their support of OASIS format and new versions of EDA tools which can handle with OASIS files have been shipped one by one. Still,

As patterns on photomasks are getting more complex due to RET technologies, mask rule check (MRC) has become an essential process before manufacturing photomasks. Design rule check (DRC) tools in the EDA field can be applied for MRC. However, photoma

We have been developing intellectual properties (IP) protection software using OASIS format. In the Photomask Technology 2004 we presented that by taking advantage of repetition presentation of OASIS, it becomes possible to express arrayed patterns w

In this paper we present new development of intellectual properties(IP) protection software using OASIS format. By taking advantage of repetition presentation of OASIS, it becomes possible to express arrayed patterns without any generation of new cel

The contact layer has been said to be the first application of NGL technologies such as EPL or LEEPL, in which stencil masks are used. Since the computation time depends on the number of edges of patterns, contact layer data which contains many recta

EPLON is the name of a system that we have been developing as a data conversion system for EPL masks in order to meet the requirements of EPL stencil masks. In our paper we presented in PMJ2002, we proved that our system could convert the whole chip
