Samsung has significantly reduced the error rate when releasing 4nm chips, which has attracted AMD and Google

Samsung’s 4nm process suffered from high rejection rates for a long time until significant progress was made in the past few weeks. Samsung representatives personally reported this on local social networks, which happens extremely rarely. It is stated that “The next generation of 4 nm process technology will deliver higher yields” and it attracted significant customers – AMD and Google.

As we know, Samsung will start mass production of chips based on the third generation of 4nm process technology within this half year. This comes about two years after the first application for the start of production of what will then be the first generation of 4 nm solutions. Although Samsung is not far behind its Taiwanese competitor TSMC, it loses significantly in terms of the new process technology’s degree of readiness for series production.

It has been claimed that in the second year of production using 4nm standards, the yield rate of good microcircuits on Samsung lines reached 60%, while on TSMC lines of a similar scale this figure reached 70% and even 80% (for mature production, this reaches 92-95%). Yields on Samsung’s new 4nm lines will approach TSMC and Samsung’s 5nm yield levels, which means exceeding the 70% mark or more.

Previously, Samsung lost a number of large orders from Tesla, Qualcomm and other companies because the performance of 4nm chips from each wafer was significantly inferior to TSMC. Reaching new levels of product quality allowed the South Korean chipmaker to return some of them. For example, new orders for the contract manufacturing of chips for AMD and Google are reported.
