Recent developments in LSI mask dataprocessing show a tendency towards unpreceded data volume increases. This paper introduces a data compression technique designed to reduce mask data volumes and is based on geometrical library recognition in which a library is defined as a set of patterns that can be referenced as a single object repeated along a 2 dimensional mesh. The data compression technique is referred to as mask data geometrical library recognition compression (MD-GLRC) and includes a newly developed repetition center tracking (RCT) and library inheritance tree (LIT) algorithm. By applying MD-GLRC, a 885 Mbyte 0.25 μm memory device mask data sample was compressed to 7 Mbytes in 3.5 CPU hours on a 135 MIPS workstation.

With mask dataprocessing becoming increasingly complex, there is a growing need for mask data verification. An eb graphical image browser was developed to support mask data verification and was designed to allow high speed visualization of large data volumes such as typically found in ULSI designs. The eb browser uses an intermediate format in order to support multiple ebdata formats. The software implementation allows for portability between computer platforms commonly used in a CAD framework.
