标题： Yield, noise and timing studies of ALICE ITS3 stitched sensor test structures: the MOST

摘要： 在LHC长期停机3期间，ALICE实验将其内跟踪系统内部层升级为三层围绕束流管道弯曲的晶片级拼接传感器。 两个拼接传感器评估结构，即单片拼接传感器（MOSS）和带时间的单片拼接传感器（MOST），允许研究电路密度、电源分割、用于电源和数据传输的拼接演示、反向偏置对性能的影响、电荷收集性能、芯片上参数的一致性以及晶片级数据传输的性能。 MOST的尺寸为25.9厘米×0.25厘米，拥有超过900,000个18x18$\mu$m$^2$的像素，并强调了最大密度的像素电路验证，同时还具有大量由开关分隔的电源域，允许断开故障电路。 它采用异步、数据驱动的读出方式，进行26厘米长的数据传输，速率为1 Gb/s。 这种读出方式保留了像素地址、到达时间和阈值时间的信息。 相比之下，在MOSS中，实现了不同像素密度的区域以研究良率依赖性，并且是同步读取的。 MOST测试结果验证了电源域切换的概念以及将在全尺寸、全功能ITS3原型传感器MOSAIX上使用的26厘米拼接线的数据传输。 此传输的抖动仍在研究中。 本文总结了拼接传感器测试结构的性能，重点在于MOST。 显示英文摘要

摘要： In the LHC long shutdown 3, the ALICE experiment upgrades the inner layers of its Inner Tracker System with three layers of wafer-scale stitched sensors bent around the beam pipe. Two stitched sensor evaluation structures, the MOnolithic Stitched Sensor (MOSS) and MOnolithic Stitched Sensor with Timing (MOST) allow the study of yield dependence on circuit density, power supply segmentation, stitching demonstration for power and data transmission, performance dependence on reverse bias, charge collection performance, parameter uniformity across the chip, and performance of wafer-scale data transmission. The MOST measures 25.9 cm x 0.25 cm, has more than 900,000 pixels of 18x18 $\mu$m$^2$ and emphasizes the validation of pixel circuitry with maximum density, together with a high number of power domains separated by switches allowing to disconnect faulty circuits. It employs 1 Gb/s 26 cm long data transmission using asynchronous, data-driven readout. This readout preserves information on pixel address, time of arrival and time over threshold. In the MOSS, by contrast, regions with different in-pixel densities are implemented to study yield dependence and are read synchronously. MOST test results validated the concept of power domain switching and the data transmission over 26 cm stitched lines which are to be employed on the full-size, full-functionality ITS3 prototype sensor, MOSAIX. Jitter of this transmission is still under study. This proceeding summarizes the performance of the stitched sensor test structures with emphasis on the MOST.
