New ITS Design goals
1. Improve impact parameter resolution by a factor of ~3• Get closer to IP (position of first

Results of the flip-chip mounting • Radius of solder balls does not affect the total material budget much (0.002%) • The thickness of the flex cable contributes significantly to the total material budget
Our studies confirm the material budget for inner layers : X/X0 /layer ~ 0.3%
