Ordering has been already done.
◦ Total cost: 4M JPY
◦ Half of them is covered by KEK (ATLAS-J), and another
half is covered by Kobe U. (Detector R&D budget).
◦ The small modification for drawings will be needed.
◦ Proof check of the pattern will be done in this week.
◦ Mask production … 1.5 weeks
◦ Image development on the foil … 1 week (Laytech)
◦ The sputtering will be available at end of this year or the
beginning of the next year. (Be-sputter)
