Lam Research Advances Next Generation 3D Memory Manufacturing with Revolutionary New Etch Technology
Vantex™ redefines high aspect ratio etching with new innovations in technology and Equipment Intelligence® enabling chipmakers to progress 3D NAND and DRAM roadmaps
Chipmakers building 3D memory devices used in applications such as smartphones, graphics cards, and solid-state storage drives continually strive to reduce their cost per bit from node to node by increasing device dimensions vertically and reducing critical dimensions (CD) laterally. This is driving etch aspect ratios in 3D NAND and DRAM to new levels.
Vantex’s new chamber design enables the use of higher than previously available radio frequency (RF) power levels in order to etch high aspect ratio features at high throughput and achieve cost scaling. The increased power is coupled with advancements in RF pulsing technology to deliver the tight CD control required to improve device performance.
The 3D NAND device roadmap requires etching to achieve greater depths with every new generation, driving a need for improved etch profile uniformity. The Vantex technology controls the vertical angle of the etch to meet the tighter placement requirements of these 3D device features and achieve high yield across the entire 300mm wafer.
“With more than a decade of industry leadership in high aspect ratio etch, our unique learning enabled the Vantex chamber design from the ground up to offer scalability and innovation for many nodes to come,” said
Lam’s Sense.i etch platform with Equipment Intelligence® includes capabilities for collecting data from hundreds of sensors monitoring system and process performance. The Vantex chamber leverages the high bandwidth communication in the Sense.i system to collect more data per wafer than any other tool on the market – with the ability to utilize data much more efficiently in order to improve both on-wafer and wafer-to-wafer performance.
