Multi-beam mask writer MBM-1000 will be released in Q4 2017 for N5 semiconductor production. Performance of MBM-1000 is under verification and tuning by using alpha tool upgraded to high-volume manufacturing (HVM) system. It is designed to realize better resolution and higher throughput than EBM-9500, our latest variable-shaped-beam writer, at shot count higher than 500 Gshot/pass. Writing test after upgrade confirmed that MBM-1000 has better beam resolution than EBM-9500 as expected by optics design. It also showed that position of beam array projected on target was stable during one hour writing enough to accomplish registration target. Design of data transfer system and BAA for 300-Gbps data rate is described.
