Design and properties of the GLAST flight silicon micro-strip sensors

We have designed and developed the flight model silicon micro-strip detector (FM-SSD) for Large Area Space Telescope (GLAST). The concepts and details of the sensor design are described and the results of production testing of the SSDs are reported. A total of 11,500 FM-SSDs were produced in the 2-yr time span from the start of 2001 to the end of 2003. The fabrication was done on the 6-in process line at Hamamatsu Photonics Company. The properties of each SSD were determined by measuring a set of specific parameters. The leakage current and dead channel rate establish a new performance standard for SSD mass production, indicating that the SSD design and fabrication technologies have been well optimized and are well matured.
