Objectives
INFINIT has one main objective:
To gain a deep understanding of the N7 FinFET process technology for use in digital space applications.
In addition, two sub objectives are considered:
-
Create a minimum set of hardened standard cells
-
Establish a standardized radiation evaluation test vehicle approach for fast(er) evaluation of new advanced process technologies.
The starting TRL of the activity is TRL1: there are only a few publications on very specific radiation aspects, no structured technology evaluation exists.
The end TRL of the activity is TRL4: the radiation evaluation of the technology will be done by extensive validation of critical radiation aspects in a relevant environment and representative radiation models will be developed.
Challenges
INFINIT is a pre-cursor project for the ESA UDSM programme. Further projects depend heavily on the outcome of INFINIT. Therefore, timely presentation of final results as well as having a baseline radiation-hard library is of utmost importance for further success of the N7 technology implementation in near-future space projects.
System Architecture
A 5 mm2 ASIC consisting of two sub-dies: RETVD (digital test vehicle) and RETVA (analogue test vehicle), to be bonded mutually exclusively.
The Analog Test Vehicle contains transistor arrays and allows for highly accurate measurement of TID-induced effects.
The Digital Test Vehicle contains a mix of standard cells (foundry supplied) as well as a small set of RAD-hard custom cells to evaluate the effects of TID and mostly SEE on the N7 FinFET process technology.
Plan
Definition phase (WP1)
Technology exploration and test vehicle definition.
Milestones: KO, SRR, ADR
Design & manufacturing phase (WP2, 3, 4)
Design of test vehicle, test hardware, test software
Manufacturing and assembly of test vehicle, test hardware
Milestones: PDR, DDR, CDR
Test phase (WP5, 6)
Electrical and irradiation testing, and ASIC library design update
Milestones: TRR, DVR, FR
Current Status
The technical preparation phase (WP1) has been successfully completed and the design partners are now preparing the preliminary design for an analogue and a digital radiation evaluation test vehicle. This includes the development of a set of test structures for TID and SEE irradiation, as well as a continuation of the initial technology definition work into the actual packaged samples.
