To provide a semiconductor device manufacturing method of making a pattern formation possible with high precision at a high speed, the same block can be completed by one process a cell by dividing the layout data into cells in the OPC processing step and then applying the OPC to each cell, and the OPC is applied only to the cell boundary portions after respective OPC-applied cells are arranged on the chip, so that a dimensional precision in vicinity of the cell boundaries can be ensured. Also, since the patterns on the cell boundary portions are caused to shrink uniformly, the OPC of the cell boundary portions can be simplified and thus the fast process can be applied.

In a system where a plurality of sensor nodes are distributed and communication is performed between the distributed nodes by using an encryption key, a key required for communication is flexibly specified for each node and stored even when node arrangement is irregular or a plurality of distribution methods are used. An area dividing unit (611) divides a space as a node distribution object into predetermined small spaces. A key generation unit (612) generates an identical number of keys to the number of small spaces, causes a key pool storage area (613) to store the keys while correlating the small spaces to the keys. An arrangement sampling unit (614) predicts arrangement points of the respective nodes according to the probability density function, selects small spaces within a range communicable from the arrangement point of each predicted node, and specifies the key assigned for the selected small space as a storage object. This processing is repeated until a predetermined number of keys are specified for one node and a key write unit (615) writes the key specified by the arrangement sampling unit (614) in the node.
