Due to the large expected instantaneous luminosity, the future HL-LHC upgrade sets strong requirements on the radiation hardness of the CMS detector Inner Tracker. Sensors based on 3D pixel technology, with its superior radiation tolerance, comply with these extreme conditions. [...]

A new generation of radiation hard 3D pixel sensors for the ATLAS upgrade
/ Terzo, Stefano (Barcelona, IFAE) ; Grinstein, Sebastian (Barcelona, IFAE ; ICREA, Barcelona) ; Manna, Maria (Barcelona, Inst. Microelectron.) ; Pellegrini, Giulio (Barcelona, Inst. Microelectron.) ; Quirion, David (Barcelona, Inst. Microelectron.)
The ATLAS experiment at the Large Hadron Collider (LHC) will replace its inner tracker system to cope with the extreme particle fluence expected after the High Luminosity upgrade of the accelerator (HL-LHC). The 3D silicon sensor technology has been selected as baseline to instrument the innermost layer of the pixel detector in the future ATLAS Inner Tracker (ITk). [...]

First measurements of segmented silicon tracking detectors with built-in multiplication layer
/ Cavallaro, Emanuele (Barcelona, IFAE) ; Lange, Jörn (Barcelona, IFAE) ; Lopez Paz, Ivan (Barcelona, IFAE) ; Grinstein, Sebastian (Barcelona, IFAE) ; Baselga, Marta (Barcelona, Inst. Microelectron.) ; Greco, Virginia (Barcelona, Inst. Microelectron.) ; Quirion, David (Barcelona, Inst. Microelectron.) ; Pellegrini, Giulio (Barcelona, Inst. Microelectron.)
Silicon sensors with a built-in multiplication layer, also known as Low Gain Avalanche Detectors (LGAD), are a new technology of potentially radiation hard silicon sensors developed at CNM (Centro Nacional de Microelectrónica) in the framework of the CERN-RD50 collaboration. The concept of the LGAD technology is to produce a tracking sensor with an intrinsic low gain due to charge multiplication in order to enhance the signal-to-noise ratio. [...]

Rad-hard vertical JFET switch for the HV-MUX system of the ATLAS upgrade Inner Tracker
/ Fernandez-Martinez, Pablo (Barcelona, Inst. Microelectron.) ; Ullan, Miguel (Barcelona, Inst. Microelectron.) ; Flores, David (Barcelona, Inst. Microelectron.) ; Hidalgo, Salvador (Barcelona, Inst. Microelectron.) ; Quirion, David (Barcelona, Inst. Microelectron.) ; Lynn, David (Brookhaven)
This work presents a new silicon vertical JFET (V-JFET) device, based on the trenched 3D-detector technology developed at IMB-CNM, to be used as switches for the High-Voltage powering scheme of the ATLAS upgrade Inner Tracker. The optimization of the device characteristics is performed by 2D and 3D TCAD simulations. [...]

Design and Fabrication of an Optimum Peripheral Region for Low Gain Avalanche Detectors
/ Fernandez-Martinez, Pablo (Barcelona, Inst. Microelectron.) ; Flores, David (Barcelona, Inst. Microelectron.) ; Hidalgo, Salvador (Barcelona, Inst. Microelectron.) ; Greco, Virginia (Barcelona, Inst. Microelectron.) ; Merlos, Angel (Barcelona, Inst. Microelectron.) ; Pellegrini, Giulio (Barcelona, Inst. Microelectron.) ; Quirion, David (Barcelona, Inst. Microelectron.)
Low Gain Avalanche Detectors (LGAD) represent a remarkable advance in high energy particle detection, since they provide a moderate increase (gain ~10) of the collected charge, thus leading to a notable improvement of the signal-to-noise ratio, which largely extends the possible application of Silicon detectors beyond their present working field. The optimum detection performance requires a careful implementation of the multiplication junction, in order to obtain the desired gain on the read out signal, but also a proper design of the edge termination and the peripheral region, which prevents the LGAD detectors from premature breakdown and large leakage current.

Prototype ATLAS IBL Modules using the FE-I4A Front-End Readout Chip
/ ATLAS IBL Collaboration
The ATLAS Collaboration will upgrade its semiconductor pixel tracking detector with a new Insertable B-layer (IBL) between the existing pixel detector and the vacuum pipe of the Large Hadron Collider. The extreme operating conditions at this location have necessitated the development of new radiation hard pixel sensor technologies and a new front-end readout chip, called the FE-I4. [...]
