在这个ATLAS升级研发项目中,我们探索了使用深亚微米HV-CMOS工艺来生产传统辐射硬硅传感器的嵌入式替代品的概念。这种有源传感器包含简单的电路,例如放大器和鉴别器,但仍然需要传统的(像素或条带)读出芯片。这种方法产生map的大多数优点(提高分辨率,降低成本和材料预算等),而没有完全集成在单个芯片上的复杂性。在概述了HV2FEI4测试专用集成电路的基本设计之后,将给出862 Mrad的x射线照射和1016(1 MeV neq)/cm2的中子照射后的结果。最后,对今后的发展规划作了简要展望。
In this ATLAS upgrade R&D project, we explore the concept of using a deep-submicron HV-CMOS process to produce a drop-in replacement for traditional radiation-hard silicon sensors. Such active sensors contain simple circuits, e.g. amplifiers and discriminators, but still require a traditional (pixel or strip) readout chip. This approach yields most advantages of MAPS (improved resolution, reduced cost and material budget, etc.), without the complication of full integration on a single chip. After outlining the basic design of the HV2FEI4 test ASIC, results after irradiation with X-rays to 862 Mrad and neutrons up to 1016(1 MeV neq)/cm2 will be presented. Finally, a brief outlook on further development plans is given.
