A monolithic pixel sensor (TRAPPISTe-2) for particle physics instrumentation in OKI 0.2μmSOI technology

Abstract

A monolithic active pixel sensor for charged particle tracking has been developed within the frame of a research and development project called TRAPPISTe (Tracking Particles for Physics Instrumentation in SOI Technology). TRAPPISTe aims to study the feasibility of developing a monolithic pixel sensor with SOI technology. TRAPPISTe-2 is the second prototype in this series and was fabricated with an OKI 0.20μm fully depleted (FD-SOI) CMOS process. This device contains test transistors and amplifiers, as well as two pixel matrices with integrated 3-transistor and amplifier readout electronics. The results presented are based on the first electrical measurements performed on the test structures and laser measurements on the pixel matrices.
