3D Sensor Processing - IBL G. Darbo – INFN / Genova Venezia, 4 June IBL Organization The IBL (Insertable B-Layer) is an ATLAS Upgrade project: It will deliver a fourth pixel layer, including a new beam-pipe, to the Inner Detector When delivered, it will become a part of the Pixel Detector and of the Inner Detector and the organization will be absorbed into the Pixel & ID Module WG IBL MB (Management Board) IBL MB (Management Board) Stave WG Stave WG I&I WG I&I WG Off-det WG Off-det WG IBL IB (Institute Board) IBL IB (Institute Board) Pixel Institutes in IBL Pixel Institutes in IBL New Institutes in IBL New Institutes in IBL ATLAS UPO ATLAS UPO ATLAS UPGRADE IBL IBL PL IBL TC

3D Sensor Processing - IBL G. Darbo – INFN / Genova Venezia, 4 June Modules & Stave Arrangement Two module options: Single chip modules abut one against the next Small sensor type: like 3D, active edge Multi chip modules: chip look the same if using multi-chip modules As present sensor size (~2xFE-I4) : like planar n-on-n assuming no Z-shingling, no space. W-bond pads

3D Sensor Processing - IBL G. Darbo – INFN / Genova Venezia, 4 June Requirements - Fluence Requirements discussed in previous meetings New simulation of n fluences as input for the IBL design (see box) Other requirements are: IBL design Peak Luminosity = 3x10 34, Integrated Luminosity seen by IBL = 550 fb -1 Fit made for 2 < r < 20 cm for L=1000fb -1 Gives for 3.7 cm (550 fb -1 ): 1MeV =2.4x10 15 (1.2 MGy) Safety factors not included in the computation (pp event generator: 30%, damage factor for 1 MeV fluences: 50%) Ref.

3D Sensor Processing - IBL G. Darbo – INFN / Genova Venezia, 4 June Sensors - Time line IBL project started now: TDR March 2010 – sensor option not decided before FE-I4.v1 prototyping FE-I4.v1 submitted (earliest) 15/10/2009 – Wafer back 31/4/2010 FE-I4.v1 prototype modules and testing – second half 2010 Sensor decision on FE-I3 and FE-I4.v1 prototypes End of 2010 Sensor production and testing 8 months production assumed. Testing could last 4 months after end production. Production starts beginning 2011.

3D Sensor Processing - IBL G. Darbo – INFN / Genova Venezia, 4 June How Many 3D Sensor Wafers For IBL we need: 14 staves (+6 spares) 32 FE-I4 (3D sensors) Total need = 640 single FE-I4 tiles = 54 Wafer If we consider yields: Sensor (0.5) Bump Bonding Module ~ 150÷200 wafer for whole IBL 4 Wafer – Fits 12 FE-I4
