As pattern size becomes very small, it has been getting difficult to correct an EB proximity effect accurately. We have developed a new proximity effect correction which corrects dose by simulating the energy scattering. It can correct accurately in reasonable computing time. We will explain how to improve efficiency of energy deposit simulation and evaluate the algorithm in this paper.

As pattern size becomes very small, it has been getting difficult to correct an EB proximity effect accurately. We have developed a new proximity effect correction which corrects dose by simulating the pattern width. It can correct accurately a pattern of 100nm and below.

We are developing a NGL data conversion system for EPL, for LEEPL, and for EBDW, which is based on our established photomask data conversion system, PATACON PC-cluster. For EPL data conversion, it has SF division, Complementary division, Stitching, Proximity effect correction, Alignment mark insertion, EB stepper control data creation, and Mask inspection data creation. For LEEPL data conversion, it has Pattern checking, Complementary division, Stitching, Stress distortion correction, Alignment mark insertion, and Mask inspection data creation. For EB direct-writing data conversion, it has Proximity effect correction and Extraction of aperture pattern for cell projection exposure.

PATACON-EPL is a software product for converting semiconductor mask CAD data to the EB data of masks for EB steppers. This software has several functions, such as pattern placement corresponding to the structure of masks for EB steppers, complementary division for stencil masks, stitching for deforming the shape of a portion for connecting divided portions, proximity effect correction, machine control data generation, mask inspection data generation, and alignment mark insertion. This software operates in the environment in which several to some hundreds of Linux PC's are connected by a high-speed network.
PATACON-LEEPL is a software product for converting semiconductor mask CAD data to the EB data of masks for LEEPL transcribing devices. This software has several functions, such as pattern placement function corresponding to the structure of the LEEPL mask, which is different from the mask for optical steppers, complementary division function for stencil masks, correction of distortion due to mask internal stress, and alignment mark insertion. This software operates in the environment in which several to some hundreds of Linux PC's are connected by a high-speed network.
