DESCRIPTION (provided by applicant): Propose to combine standard commercial CZT crystals and ASICS with Aguila Technologies' proprietary high-density CZT detector bonding methods and very dense electronic packaging capability to develop high resolution (less than 1 mm pixel pitch) imaging CZT gamma detectors. The aim is that the proposed detector modules could be manufactured in large quantities relatively inexpensively. The proposed detector module will comprise a single 19.6 x 19.6 x 5-mm CZT crystal in a high-density sensor package that will include four ASIC readout chips. The crystals will be partitioned into 512 anodes. Pixel pitch will be about 850-mu m, with 50-mu m streets and a 100-mu m border. The readout ASIC chips are mounted on an interposer card that is, in-turn, flip-chip bonded to the CZT array on one side and an array connector on the other. The proposed detector with its four readout ASICs will be assembled into small, self-contained modules that can be plugged into an array of sockets on a motherboard to create a large tiled array of sensors with no dead space between them. A central program objective is to fabricate and deliver to investigators in the field of small animal gamma ray imaging fully functional detector modules and test boards to integrate the detectors into functional imaging systems.

描述（由申请人提供）： 建议将联合收割机标准商用CZT晶体和ASICS与Aguila Technologies专有的高密度CZT探测器接合方法和非常密集的电子封装能力相结合，以开发高分辨率（像素间距小于1 mm）成像CZT伽马探测器。目的是所提出的检测器模块可以相对便宜地大量制造。拟议的探测器模块将包括一个19.6 x 19.6 x 5 mm的CZT晶体，采用高密度传感器封装，其中包括四个ASIC读出芯片。晶体将被划分为512个阳极。像素间距约为850亩，街道50亩，边界100亩。读出ASIC芯片安装在插入卡上，插入卡又在一侧倒装芯片接合到CZT阵列，在另一侧倒装芯片接合到阵列连接器。拟议的探测器及其四个读出ASIC将被组装成小型的独立模块，这些模块可以插入主板上的插座阵列中，以创建一个大型的传感器阵列，它们之间没有死区。 一个中心计划的目标是制造和提供给小动物伽马射线成像领域的研究人员全功能探测器模块和测试板，将探测器集成到功能成像系统中。
