Summary
• IPHC group has long history in developing CMOS Pixel Sensors (CPS), and build CPS detectors for many experiments.
• Japanese group has developed SOI pixel process. It showed high performance in position resolution, energy resolution, pixel size, radiation tolerance etc., which are necessary in future experiments.
• In collaboration of these two groups, large synergy will be expected.
