Abstract This article describes the methodology used to derive the 22FDX® Fully-Depleted Silicon-On-Insulator (FDSOI) Chip Package Interaction (CPI) qualification envelope. In the first part it is discussed how the individual market segments influence the technology features and offerings, including BEOL stacks and package types. In the following, the criteria used for the selection of BEOL stacks, die and package sizes and the interconnect type for the qualification envelope are summarized and explained. The three CPI qualification stages and related characterization methods are presented. CPI test structures used in the envelope are reported and their placement on the technology qualification vehicles (TQV) is outlined on the basis of flip chip TQV. Finally, the paper presents the passing 22FDX® package and board level reliability results obtained for wire bond, flip chip, as well as wafer level fan-in and fan-out package technologies. Key aspects of the individual qualifications are reported.
