  4. Technologies • In house • All processesrelated to Photolithographytechnics • Chemical and electrochemicalplating • CNC dilling and milling for small pattern • Chemicaletching of metals and dielectrics • Vacuum + high pressure gluing • Screen printing (metal , dielectrics and resistors) • Clean rooms ( class 100 , 1000 and 10000) • Close collaboration withindustry for: • Vacuum deposition ( Metalresistorsdielectrics) • Laser drilling and milling • Plasma etching (RIE) • Large PCBs mass production • Large screen printing mass production • In study • New generationInkjet printers (metalresistorsdielectrics)

  5. Resistors -A Resistor is define by: -Value Ohms -Precision % -TCR ppm/Deg C -max power W or W/m2 -breakdown voltage V -Resistivity in Ohm*m -Sheet resistance or surface resistivity in Ohm/sqr -TCR: Temperature coefficient of the resistor -Cermet: is a composite material composed of ceramic (cer) and metallic (met) materials. Rui De Oliveira

  6. Resistors for static dissipative application available at CERN • Screenprintedpolymers • Filledcavitypolymers • ScreenprintedRuOresistors • DLC vacuum depositedresistors • ResistiveKapton • All of themcanbepaterned

  7. Resistors why carbon? • @ 300 K in (Ω·m) • Silver 16·10-9 (Ω·m) • Ruthenium 71 10-9 (Ω·m) • Germanium 460·10-9 (Ω·m) • Ni/Cr 1000·10-9 (Ω·m) • Carbone 35 000·10-9(Ω·m) Rui De Oliveira

  9. Participation in RD51 • WG1 :R&D on new structures, wehave introduce: • Bulk Micromega ( with Saclay collaboration) • Resistive protections (with Atlas Collaboration) • Large GEM (with CERN GDD/CMS/INFN Frascati/TUM Munich …) • GEM embedded stretching system NS2 • WG6 :Industrialisation, our contribution: • Companies visits (more than 10) • TT transfer with selected companies • Institutes trainings

  10. Passed developments • Large size GEM • Blind GEM / Micro well • Chemical micro-vias • Bulk Micromegas • Resistive protections in Micromegas detectors • Capacitive couplings to reduce electronic channel count • Piggy Back Micromegas • Micro BULK Micromegas • PG and TPG thermal management devices • Full Aluminium circuits • Embedded active devices in flex

  11. Trainings and TT • GEM production training and TT: • Techtra 2 weeks at CERN + full technology transfer • Xiaomei Li (CIAE Beijing) 1 week at CERN • Tech-etch full technology transfer • Mecaronics full technology transfer • Close to 10 licenced companies • Micromegas production training and TT: • CEA Saclay (BULK and resistive protection) many iterations @CERN • CEA Saclay : BULK facility review @ Saclay • CIREA and ELTOS (BULK and resistive) 2 Days @ CERN + 2 days @ ELTOS + full TT • INFN Frascati (Large Micromegas detector) 2 months @CERN • THGEM production • VECC KolKata (polyurethane protection) 1 day @CERN • Weissmann institute Israel (test and Cleaning) 2 days @CERN
