原英文标题： <Samsung Electronics to Begin Mass Production of Third-Generation 4-nm Products in 1st Half of 2023>
Samsung Electronics will begin mass production of third-generation 4-nm chips, the main item in the foundry ultra-micro fabrication process sector, during the first half of this year. While stabilizing the yield, which was a problem in the early stages of the process, the Korean semiconductor giant succeeded in technological advancements in performance, power consumption, and area improvement compared to the initial process, which gave the Korean chipmaker the green light with regard to attracting large corporate customers.
According to a Samsung Electronics business report released on March 12, Samsung Electronics will begin mass production of chips through a 4-nm 2.3-generation process in the first half of this year. This was the first time that Samsung Electronics mentioned the specific mass production time of a 4-nm follow-up version. Second- and third-generation products show better performance, lower power consumption, and use smaller areas compared to SF4E, an early version of 4-nm chips. Even after the commercialization of the SF4E chip, Samsung Electronics went through great difficulties in the management of the chip’s yields, finally losing Qualcomm, the largest customer of Samsung Electronics, to TSMC.
However, Samsung Electronics stably raised its production capacity since the yields of its 4-nm process were put on the right track beginning in 2022. Industry insiders estimate Samsung Electronics’ 4-nm process yield at 60 percent. Although Samsung Electronics’ yield has not yet reached the yield of TSMC, which is known to be in the 70-80 percent range, experts say that its yield is improving rapidly and mass production of the follow-up version is also accelerating.
Since Samsung Electronics had a breakthrough in solving technical challenges such as improving performance and yields in advanced processes, its competition with TSMC is expected to heat up in the mass production of the ultra-micro fabrication processes for 5-nm or more advanced chips.
Currently, the most advanced semiconductor process technology stands at 3 nanometers, but the main products are still on 4- and 5-nm chips. According to Counterpoint Research, a market research firm, as of the third quarter of last year, 4- and 5-nm processes accounted for 22 percent, the highest, of sales, eclipsing 6- and 7-nm processes (16 percent) and 16-, 14- and 12-nm processes (11 percent). TSMC plans to mass-produce 4-nm chips at its Phoenix, Arizona plant scheduled to go into operation in 2024. Samsung Electronics is also building a 4-nm production line at its foundry plant in Taylor, Texas, with the goal of beginning its operations in the second half of 2024.
三星电子将在今年上半年开始大规模生产第三代4纳米芯片，这是代工超微制造工艺领域的主要项目。在稳定产量的同时，韩国半导体巨头在性能、功耗和面积方面的技术进步与最初的工艺相比获得了成功，这为韩国芯片制造商在吸引大型企业客户方面开了绿灯。
根据三星电子3月12日发布的一份商业报告，三星电子将在今年上半年开始通过4纳米2.3代工艺大规模生产芯片。这是三星电子首次提到4纳米后续版本的具体量产时间。与4纳米芯片的早期版本SF4E相比，第二代和第三代产品显示出更好的性能，更低的功耗，并且使用更小的面积。即使在SF4E芯片商业化之后，三星电子在芯片的产量管理方面经历了巨大的困难，最终将三星电子的最大客户高通公司输给了台积电。
不过，自从2022年开始，三星电子的4纳米工艺的良率走上正轨后，三星电子稳定地提高了其产能。业内人士估计，三星电子的4纳米工艺良率为60%。虽然三星电子的良品率还没有达到台积电的良品率，众所周知，台积电的良品率在70%-80%之间，但专家表示，其良品率正在迅速提高，后续版本的大规模生产也在加速进行。
由于三星电子在解决提高先进工艺的性能和良率等技术难题方面取得了突破性进展，其与台积电的竞争有望在5纳米或更先进芯片的超微制造工艺的大规模生产中升温。
目前，最先进的半导体工艺技术站在3纳米，但主要产品仍在4纳米和5纳米芯片上。根据市场研究公司Counterpoint Research的数据，截至去年第三季度，4-和5-纳米工艺占销售额的22%，是最高的，超过了6-和7-纳米工艺（16%）以及16-、14-和12-纳米工艺（11%）。台积电计划在其亚利桑那州凤凰城的工厂大规模生产4纳米芯片，计划于2024年投入运营。三星电子也在其位于德克萨斯州泰勒的代工工厂建设一条4纳米生产线，目标是在2024年下半年开始运营。 三星4nm=5nm+≈台积电7nm? 本帖最后由 埃律西昂 于 2023-3-13 15:38 编辑

三星4nm=5nm+≈台积电7nm?
4LPX=5LPP=SF5
真正已知的唯一一款三星4nm量产产品就是E2200，SF4=4LPE。
看密度的话，按Skyjuice的测试N5和4LPE实际一个水平，但4LPE比较而言功耗难看。
然后4LPP基本啥消息都没。[困惑] 只想说哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈 老黄：再信三星工艺，我就是个锤子，当然，价格合适，必入[怪脸]
