List of Items Controlled
Related Controls: 1. ECCN 3E905 applies to process “technology” exclusively for the “development” or “production” of GAAFET structures of integrated circuits at a semiconductor wafer production facility. ECCN 3E905 does not, for example, control an integrated circuit design such as the physical layout file in “GDSII” format or EDA tools, or any other technology used to produce the physical layout file for integrated circuit design. 2. ECCN 3E905 does not apply to vertical GAAFET architectures, e.g., those used for 3D NAND.
Related Definitions: N/A
Items: The list of items controlled is contained in the ECCN heading.
Note 1:
3E905 includes 'process recipes'.
Note 2:
3E905. does not apply for tool qualification or maintenance.
Technical Note:
