The Quest For Curvilinear Photomasks

By Mark LaPedus - 15 Apr, 2021 - Comments: 1

The semiconductor industry is making noticeable progress on the development of advanced curvilinear photomasks, a technology that has broad implications for chip designs at the most advanced nodes and the ability to manufacture those chips faster and cheaper. The question now is when will this technology move beyond its niche-oriented status and ramp up into high-volume manufacturing. For ye... » read more

EUV Pellicle, Uptime And Resist Issues Continue

By Mark LaPedus - 26 Sep, 2018 - Comments: 0

Extreme ultraviolet (EUV) lithography is moving closer to realization, but several problems involving scanner uptime, photoresists and pellicles need to be resolved before this long-overdue technology is put into full production. Intel, Samsung and TSMC are hoping to insert EUV into production at 7nm and/or 5nm. While the remaining issues don’t necessarily pre-empt using EUV, they do affec... » read more

Next-Gen Mask Writer Race Begins

By Mark LaPedus - 19 Oct, 2017 - Comments: 5

Competition is heating up in the mask writer equipment business as two vendors—Intel/IMS and NuFlare—vie for position in the new and emerging multi-beam tool segment. Last year, Intel surprised the industry by acquiring IMS Nanofabrication, a multi-beam e-beam mask writer equipment vendor. Also last year, IMS, now part of Intel, began shipping the world’s first multi-beam mask writer f... » read more

Hirokazu Yamada, a board member and the director of the Mask Lithography Division of NuFlare, sat down with Semiconductor Engineering to discuss photomask technology, e-beam mask writer trends and other topics. NuFlare is the world’s largest supplier of e-beam mask writers. What follows are excerpts of that conversation. SE: How does the [getkc id="265" kc_name="photomask"] market look in... » 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
