Abstract:
This paper reports on the current status of the development of International Linear Collider vertex detector pixel readout chips based on multi-tier vertically integrated electronics. Initial testing results of the VIP2a prototype are presented. The chip is the second embodiment of the prototype data-pushed readout concept developed at Fermilab. The device was fabricated in the MIT-LL 0.15 μm fully depleted SOI process. The prototype is a three-tier design, featuring 30×30 μm2 pixels, laid out in an array of 48×48 pixels.
