Multi-Beam Market Heats Up

se_logoBy Mark Lapedus

The multi-beam e-beam mask writer business is heating up, as Intel and NuFlare have separately entered the emerging market.

In one surprising move, Intel is in the process of acquiring IMS Nanofabrication, a multi-beam e-beam equipment vendor. And separately, e-beam giant NuFlare recently disclosed its new multi-beam mask writer technology.

As a result of the moves, the Intel/IMS duo and NuFlare will now race each other to bring multi-beam mask writers into the market. Still in the R&D stage, these newfangled tools promise to speed up the write times for next-generation photomasks, although there are still challenges to bring this technology into production.

What’s the Next-Gen Litho Tech? Maybe All of Them

semimd_logoBy Jeff Dorsch

The annual SPIE Advanced Lithography symposium in San Jose, Calif., hasn’t offered a clear winner in the next-generation lithography race. It’s becoming clearer, however, that 193i immersion and extreme-ultraviolet lithography will co-exist in the future, while directed self-assembly, nanoimprint lithography, and maybe even electron-beam direct-write technology will fit into the picture, too.

At the same time, plasma deposition and etching processes are assuming a greater interdependence with 193i, especially when it comes to multiple patterning, such as self-aligned double patterning, self-aligned quadruple patterning, and self-aligned octuple patterning (yes, there is such a thing!).
