A digital broadcast transmitting system and a signal processing method thereof that improves the receiving performance of the system. A digital broadcast transmitter includes a randomizer to receive and randomize a transport stream into a specified position of which stuff bytes are inserted, a replacement sequence generator to generate known data including a predefined sequence, a stuff-byte exchange unit to insert the known data into the specified position of the transport stream into which stuff bytes are inserted, an encoder to encode the transport stream output from the stuff-byte exchange unit for an error correction, and a transmission unit to modulate the encoded transport stream, RF-convert the modulated transport stream and transmit the RF-converted data. The digital broadcast receiving performance is improved even in an inferior multi-path channel by detecting the known data from the received transmission and using the known data for synchronization and equalization.

A semiconductor substrate is mounted on a semiconductor alignment apparatus. A chip alignment step is performed to center a central chip on the semiconductor substrate with respect to the semiconductor alignment apparatus, and to store the coordinates thereof. A semiconductor substrate alignment is performed to virtually align the semiconductor substrate with the semiconductor alignment apparatus. At this time, coordinates of a chip adjacent to the central chip and of a number of chips in a peripheral region of the semiconductor substrate are stored in the alignment apparatus. In addition, at least two templates are located in the central chip, and images and coordinates of the templates are stored in the semiconductor alignment apparatus during the semiconductor substrate alignment.
