Sidestepping Lithography In Chip Manufacturing

By Katherine Derbyshire - 23 May, 2024 - Comments: 0

Rising lithography costs, shrinking feature sizes, and the need for an alternative to copper are collectively spurring new interest in area-selective deposition. An extension of atomic layer deposition, ASD seeks to build circuit features from the bottom up, without relying on lithography. Lithography will remain a critical tool for the foreseeable future. But it has long been the most expen... » read more

Enabling Advanced Devices With Atomic Layer Processes

By Katherine Derbyshire - 18 Apr, 2024 - Comments: 2

Atomic layer deposition (ALD) used to be considered too slow to be of practical use in semiconductor manufacturing, but it has emerged as a critical tool for both transistor and interconnect fabrication at the most advanced nodes. ALD can be speeded up somewhat, but the real shift is the rising value of precise composition and thickness control at the most advanced nodes, which makes the ext... » read more
