摘要： A semiconductor device may include: a bus; first and second function modules configured to communicate via the bus; a first encryption module configured to encrypt first data output from the first function module using a first encryption key to generate first encrypted data; and/or a second encryption module configured to decrypt the first encrypted data using the first encryption key, to output the decrypted first data to the second function module, and to encrypt second data output from the second function module using a second encryption key to generate second encrypted data. A semiconductor device may include: a bus; first and second modules configured to communicate via the bus; and/or an encryption module configured to use different encryption policies for first data, which is output from the first module and stored in a memory, and second data, which is output from the second module and stored in the memory.

摘要： A photomask manufacturing method includes defining a main region and a dummy region based on a layout data, wherein the main region corresponds to an outer boundary surrounding functional patterns defined by the layout data and the dummy region corresponds to an empty space outside the main region, and forming a dummy pattern to fill the dummy region. The forming of the dummy pattern includes placing at least one first pattern block in the dummy region to form a first sub-region, each of the at least one first pattern block having a first area, and placing, after completing the placing of the at least one first pattern block in the dummy region, at least one second pattern block in the dummy region except the first sub-region to form a second sub-region, each of the at least one second pattern block having a second area smaller than the first area.
