Paper Abstract

A CdZnTe strip detector array with capabilities for arc second imaging and spectroscopy has been built as a prototype for a space flight gamma ray burst instrument. Two dimensional orthogonal strip detectors with 100 micrometer pitch have been fabricated and tested for a large area array (approximately 60 cm2 with 36 detectors). Details for the fabrication and evaluation of the detectors are presented. Critical issues to be addressed include fabricating metal contacts with low leakage current and with excellent wire bonding yield, achieving high yield for good strips, and surface cleaning and passivation.
