1. Pico-second TDC Schedule & Production

2. schedule Significant submission delay encountered.
Time and jitter critical design very delicate
Underestimate of finalizing simple things: Simple things x large N = large time
Memory integration issue
Trainee supposed to help with design, verification and test left at very unfortunate time
Integration of custom blocks
Verification took longer than expected (always does)
Prototype submission: August 2018
Initial bare die test: November - December 2018
At CERN only, to verify chip is alive
Packaging of chips: Jan. – Feb. 2019
Testing of packaged chips: March. – April 2019
At CERN plus few selected users
(Possible design corrections: May – June 2019)
Production submission: July 2019
Production chip test/verification: September - October 2019
Chips available in quantity: October 2019

4. Production scenarios, cost estimate
Masks, engineering run and packaging are dominating costs: Prices in CHF/Euro/$
12inch wafer (4kCHF) = 3.5k PicoTDCs per wafer
½ or ¼ if shared masks and process split
Dedicated engineering. run: ~500k CHF, low metal layer count
Shared engineering run: ~250k CHF (could be less if several clients)
Packaging + test: ~10 CHF per chip
Yield: ~2/3
Dedicated engineering run:
Eng run 5 wafers: 500k CHF
Chips: 5 x 3.5k 17k, ~10k working
Packaging/test: 17k x k, CHF
Cost per chip: 670k / 10k 67 CHF per chip
Price ~150 CHF per chip assuming half sold, for non commercial
Shared engineering run
Eng run 5 wafers: 250k CHF
Chips: 5 x 3.5/2 k 9k, ~6k working
Packaging/test: 9k x 10 90k CHF
Cost per chip: 340k / 6k 57 CHF per chip
Production run: Only after Engineering run
25 wafers: 100k CHF
Chips: 25 x 3.5k 90k, 60k working, half if shared run
Packaging/test: 90k x 5 450k CHF
Cost per chip: 550k / 60k 10 CHF per chip, double if shared run
Realistic scenario: 10/6 k working chips produced, 5K assured to be sold
Non commercial sales price: 150 CHF/E/$ per chip, Non commercial
2.3 CHF/E/$ per channel
Commercial use: To be negotiated on case by case
