FREMONT, Calif.—An enhanced atomic layer deposition platform developed by Lam Research Corp. is reported to address semiconductor manufacturing challenges for 3D NAND, DRAM, and Logic chipmakers. The Striker® FE platform, a new processing platform for manufacturing high-aspect-ratio chip architectures, uses an innovative, first-of-its-kind ICEFill™ technology for filling extreme structures in 3D NAND, DRAM, and logic devices at emerging nodes, Lam Research said in a release.

Traditional methods of gapfill for semiconductor manufacturing include legacy chemical vapor deposition, diffusion/furnace, and spin-on processes. These techniques are no longer viable for today’s 3D NAND requirements, as they are limited by the tradeoffs between quality, shrinkage, and gapfill voids.

Lam’s Striker ICEFill, by contrast, uses a proprietary surface modification technique to achieve what the company called “highly preferential bottom-up and void-free gapfill, while retaining the film quality inherent to atomic layer deposition (ALD).” The ICEFill technology removes existing limitations for filling high-aspect-ratio features that are especially prevalent in 3D NAND devices, the company said. It is also said to prevent collapse issues in DRAM and logic devices.

“Our goal is to provide customers with the most enabling ALD technology,” said Sesha Varadarajan, senior vice president and general manager of the deposition product group at Lam Research, in the release. “This technology combines the ability to produce high quality oxide films with superior gapfill performance, in a single processing system with the productivity advantages offered by our industry-leading quad station module architecture.”

The system delivers the continued cost and technology scaling required to meet the semiconductor industry roadmap, Lam Research said in the release.
