Inverse lithography technology: 30 years from concept to practical, full-chip reality

By Technical Paper Link - 01 Oct, 2021 - Comments: 0

Published in the Journal of Micro/Nanopatterning, Materials, and Metrology, Aug. 31, 2021. Read the full technical paper here (open access). Abstract In lithography, optical proximity and process bias/effects need to be corrected to achieve the best wafer print. Efforts to correct for these effects started with a simple bias, adding a hammer head in line-ends to prevent line-end shortening. T... » read more

Multi-Beam Market Heats Up

By Mark LaPedus - 17 Mar, 2016 - Comments: 3

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, [getentity id="22846" e_name="Intel"] is in the process of acquiring IMS Nanofabrication, a [gettech id="31058" t_name="multi-beam e-beam"] equipment vendor. And separately, e-beam giant NuFlare recently disclosed its new multi-beam mask writer t... » read more

10nm Fab Challenges

By Mark LaPedus - 21 May, 2015 - Comments: 1

After a promising start in 2015, the semiconductor equipment industry is currently experiencing a slight lull. The pause is expected to be short-lived, however. Suppliers of [getkc id="208" comment="3D NAND"] devices are expected to add more fab capacity later this year. And about the same time, foundries are expected to order the first wave of high-volume production tools for 10nm. At 10nm... » read more

Issues And Options At 5nm

By Mark LaPedus - 19 Mar, 2015 - Comments: 0

While the foundries are ramping up their processes for the 16nm/14nm node, vendors are also busy developing technologies for 10nm and beyond. In fact, chipmakers are finalizing their 10nm process offerings, but they are still weighing the technology options for 7nm. And if that isn’t enough, IC makers are beginning to look at the options at 5nm and beyond. Today, chipmakers can see a p... » read more
