Description
ALTIROC-A is the front-end readout ASIC of the ATLAS High-Granularity Timing Detector (HGTD). Its large-scale production requires reliable wafer-level screening before dicing and module assembly. This contribution presents the ALTIROC-A wafer probing campaign, focusing on measured performance, including TDC and jitter characterization, wafer-to-wafer yield spread, and the constraints relevant to large-scale quality control. In the current pre-production campaign, 16 wafers have been probed at IHEP, with an average yield of about 78% under the present acceptance criteria. The contribution addresses the probing-related effects that influence chip qualification and the definition of robust screening rules for production.
