Description
Recently (2023 (1) ) we set up a collaboration aimed for the development of the DoTPiX pixel device (2).
This type of device is designed to improve the spatial resolution of pixel detectors planned to be used in
future detectors such as the ILD. The vertex detector is the part in which the DoTPiX device is primarily
intended. The development plan is segmented into three main phases. The first phase relies on simulation
work. We use so-called TCAD to assess the detection and electrical performances of the device, and to
outline the different fabrication steps that are necessary. Much of this phase concerning electrical
performance has reached its goals. There exists still many open questions in the material processing
necessary to achieve a testable device. This is the aim of the second phase. We are now currently studying
the different processing steps with a material science point of view, in order to quantify all of these to
obtain a reliable process flow. We will describe this here and how it is organized within the DoTPiX
collaboration. Finally, we ‘ll introduce the following development steps, and how these depend on the
former development phases.
