Exynos 2400 Development On Samsung’s 4nm Process Is Showing Progress, But Company Rumored To Have Used Unethical Way To Increase Yields

After failing to launch or use any of its smartphone chipsets this year for its flagships, Samsung is rumored to be making healthy progress with its Exynos 2400, to the extent that there is a possibility that this becomes the next flagship SoC. The first obstacle was mass-producing its 4nm wafers with a higher yield, which the company appears to have done with its 3rd-generation node. However, digging around, we found the methods followed to increase those yields might not sit well with popular opinion.

A debate has sparked as to how Samsung managed to increase its 4nm yields, with one Twitter user claiming the company allegedly ‘stole’ TSMC’s ‘yield capture methods’

Samsung’s newest 4nm process is said to be called 4LPP or 4LPP+, according to Twitter user Quadrans Muralis, claiming that the company has made positive strides with the Exynos 2400. Deeming the silicon as successful, Quadrans Muralis believes that it is now up to Samsung how it wants to use the upcoming SoC. However, where he speaks about the progress of the Korean giant’s chip division, Revegnus, another Twitter user, says the company went to TSMC’s suppliers and allegedly stole their yield capture methods.

Naturally, these allegations piqued our interest, so when asked who is claiming Samsung’s unethical practices, we were provided a link to a report published by Economic News Daily. The machine translation also states what Revegnus was referring to, but the wording had us confused for a little while. Quadrans Muralis was quick to debunk the rumor, stating that Taiwanese media have failed to provide strong evidence against their claims.

There is a debate sparked between two Twitter users on Samsung, who is rumored to use an unethical way to improve Exynos 2400 yields

While their debate continues, we remind our readers that one of these Twitter users was previously engaged in an earlier conversation surrounding the Exynos 2400. Apparently, one rumor claims that the upcoming Galaxy S24 series will stick with using Qualcomm’s Snapdragon SoC exclusively, which in this case, would be the Snapdragon 8 Gen 3. Again, Quadrans Muralis was quick to jump on the Twitter thread, explaining that Samsung’s MX division had approved the mass production of the Exynos 2400.

It is no secret that one of the reasons Qualcomm shifted to TSMC to mass produce the Snapdragon 8 Gen 2 was Samsung’s poor yield rate of its 4nm process. Since that setback, we have heard and even reported about the company’s efforts to improve its yields, though it had to do with the 3nm GAA node rather than the 4nm one. Even so, mass producing wafers on the 3nm GAA process is likely more difficult, so if Samsung has increased 4nm yields, then more power to it.

Unfortunately, we cannot comment on what measures Samsung took to improve production, and even with Taiwanese media reporting the story, the evidence is simply not there for us to side with the foreign publication. We recommend our readers to treat this rumor with a pinch of salt.
