Lay-out radiation mitigation techniques

LU

Digital design SEU mitigation

• Minimize the use of N-MOS transistors (more sensitive to radiation than P-

MOS) by selecting the appropriate architectures.

• Use of P-MOS transistor for HV switch, at the expense of a higher silicon area

.

• Pseudo enclosed layout for NMOS: ensures good D/S isolation from lateral transistor with acceptable accuracy with the foundry electrical model.

• Systematic guard rings => cut inter MOSFET leakage current

• NMOS and PMOS are designed inside floating pockets => improved physical isolation.

• NMOS and PMOS are manufactured above buried layers with deep biased plugs => improved charges evacuation towards power ties .

• Use of 3-vote flip-flops for digital storage (triple mode redundancy or TMR).

• Use of special monitoring logic for SEU (EDAC

).

Vds up to 80V, N-MOS and

P-MOS.

Design restriction: HV-

NMOS not used, due to its performance in radiation shows some important leakage. -> Future activity: design RH HV NMOS.

DIGITAL TEST VEHICLES

Selection:

INVERTER CHAIN

Highest sensitive transistor area density for a given size

Each transistor is sensitive while for a

NAND or a NOR, in the stacked branch, one transistor is less sensitive

The inverter chain is also a very good test vehicle for SET sensitivity tests, due to its ability to pass very fast signals

As the digital library is designed from performances of the smallest inverter

(fanout definition…), generalization of results is easier

Large cell area of the order 15x when compared to the standard cells!!!!

CONCLUSIONS

It is not possible to provide definitive conclusions since the ASICs described herein are still at the end of the design phase and no results are available yet.

The HV functions have been developed using P-channel transistors, departing from radiation data from preliminary test performed on test vehicles from ON SEMI.

• These tests showed acceptable radiation performance for High Voltage P-channel transistors while the N-channel ones showed a high sensitivity to both heavy ions and gamma rays total cumulative dose

.

A digital test vehicle has been developed that includes new rad hard digital structures.

• These designs will be verified in a first run and provide the digital functionality of the final mixed-signal ASIC.

The main aspect to be improved will be the area ratio between the radiation hardened and the standard I3T80 digital cells (15x). Further area improvements are under investigation

.
