Samsung is ready to start mass production of third-generation 4nm chipsets


Samsung Semiconductor has been given the green light to resume mass production of third-generation 4nm chipsets, according to Korean sources. The company has been able to achieve satisfactory wafer performance from its next-generation chipsets, which help reduce power consumption.

The production process should start at the end of the first half of 2023, that is, in three months.

Yields per wafer at the Hwaseong plant were extremely low, prompting chip companies such as Qualcomm to contract with TSMC for 4nm platforms. The Taiwanese company had about 70-80% valid wafers, while Samsung barely reached 60%, and since manufacturers pay for the entire wafer, it is more profitable to go with a manufacturer with less production waste.

The next leap in advanced processing technology is 3nm, and Apple is expected to launch the iPhone 15 Pro with such platforms. Business Korea cites Counterpoint research, which found that 4nm and 5nm processes are used 22% more often in mobile devices, followed by 6nm and 7nm chips at 16%.

Production of 4nm chips is expected to increase further in the future, as Samsung and TSMC are building factories in the United States that will be ready for use in 2024.
