SMIC Removes Wording from the 14nm Node: Are US Sanctions at Work?

Semiconductor Manufacturing Worldwide Corp., China’s largest contract chip maker, quietly eliminated its 14nm fabrication expertise list of services on the website. The corporate additionally did not point out superior FinFET-based applied sciences in its earnings name final week. Reports DigiTimes.

The most recent US authorities export management guidelines prohibit Chinese language semiconductor producers from buying the instruments and applied sciences essential to manufacture 14nm/16nm or smaller non-planar transistor logic chips, 3D NAND chips with 128 or extra energetic layers, and DRAM ICs with half . -18nm or under pitch. With related restrictions from the Netherlands, Japan and Taiwan coming into impact in mid-2023, Chinese language corporations corresponding to SMIC and YMTC are introducing 3D NAND with 14nm/12nm and 14nm/12nm and N+1 for SMIC and 128-layer and 232-layer for YMTC.

With out entry to superior tools and spare components from suppliers corresponding to ASML, Utilized Supplies, KLA and Lam Analysis, SMIC could not be capable to manufacture chips for its clients utilizing the newest fabrication applied sciences, so it is sensible to take away the 14nm platform. list of technologies.

Within the meantime, 14nm continues to be talked about on the corporate’s shuttle companies web page, and it’s even said that the corporate commonly produces shuttle wafers utilizing this node.
