WebAmong many steps, high aspect ratio (HAR) ONON channel hole formation modules remained the most critical steps. Forming billions of perfect channel holes from top to bottom without distortion and twisting is the grand challenge. Besides individual etch and deposition module optimization, deposition and etch Co-optimization (DECO) could … Web2. rude slang A strong desire or affinity for something.

WebSep 20, 2024 · HAR etch is also known as deep silicon etch or deep reactive ion etch (DRIE). For HAR etch, the industry mainly uses the Bosch process. Patented in 1996, the two-step process first involves an isotropic etch using sulfur hexafluoride (SF 6 ), followed by a protection film passivation layer. WebApr 11, 2024 · Abstract. High aspect ratio (HAR) ONON channel hole patterning in 3D NAND flash presents grand challenges. This report summarizes some of the recent progresses in patterning from a HAR etch and Deposition-Etch-Co-Optimization (DECO) perspective.
