31 year old American Israeli Danny Lewin was the first victim of the September 11th attacks. Born in Denver, Colorado, in 1970, Lewin’s family moved to Israel when he was just a teenager. Danny soon served as an officer in the IDF and later attended the Technion - Israel Institute of Technology while also working full-time for IBM. In 1996, Lewin received a scholarship at MIT and moved back to the US to pursue his PhD. In 1998, he co-founded Akamai Technologies, making him a millionaire before he turned 30. On September 11, 2001, Danny was a passenger on American Airlines Flight 11. He was headed to LA on business, and at some point, he must have sensed something was wrong. According to an FBI report, in an act of heroism, Lewin attempted to stop two of the terrorists when a third terrorist fatally stabbed him from behind. This has been recorded as the first death from the 9/11 tragedy. May his memory be a blessing. Photo: Akamai

"Three out of four are defective"... China's CXMT struggles with HBM yields, with immature TSV technology to blame ChangXin Memory Technologies (CXMT), China's largest DRAM maker, has begun trial production of fourth generation high bandwidth memory (HBM3), but initial yields are barely improving. Yields are reported to have stalled at 25%, roughly one third of the so called "golden yield" of 80% that the semiconductor industry treats as the threshold for volume production. The gap is stark compared with SK hynix, which has been mass producing the same product since 2022 and has secured yields above 90%. Industry sources point to the gap in maturity of through-silicon via (TSV) technology, the core process for stacking and connecting multiple DRAM layers, as the root cause. ◇ "DRAM has caught up, but HBM stacking is a different problem" According to a senior official at a semiconductor equipment company familiar with CXMT's situation on the 9th, the yield of CXMT's HBM3 8-High product is stuck at around 30% in the front end process. Of the products that survive that stage, only about 70% are recognized as final good units after passing through the back end process. In simple terms, if 100 HBM3 units are started, close to 80 of them fail the final test. CXMT is reported to be supplying the small volumes of HBM samples it produces this way to Chinese companies such as Alibaba's T-Head and Cambricon while continuing its yield improvement work. The problem is that the issue does not lie in the fine process technology of the DRAM itself. A semiconductor equipment industry official explained, "There is no major problem with the standard DRAM that CXMT makes on its 'G4' (17nm class) process used for HBM. However, the DRAM dies used for HBM are larger in area than standard products and have more demanding electrical specifications, so even on the same process they are much harder to pass the acceptance criteria." In other words, CXMT's fundamental capability in making standard DRAM has risen to a considerable level, but a bottleneck is emerging at the stage of converting it into the high performance product that is HBM. At the heart of that bottleneck, according to industry sources, is the TSV process. ◇ The real hurdle is TSV... "Impossible to catch up without years of accumulated know how" TSV stands for "Through Silicon Via" and refers to the microscopic copper wiring that passes vertically through each layer to carry electrical signals when DRAM is stacked in multiple layers, as in HBM. It is a highly demanding process in which a DRAM wafer is thinned down to several tens of micrometers, a fraction of the thickness of a human hair, after which thousands of tiny holes are drilled through that thin silicon plate and filled completely with copper. A single hole that is misaligned or not properly filled can cause the entire layer to be rejected, making it one of the semiconductor processes with the most stringent precision requirements. The consensus in the industry is that this is the process where the technology gap between CXMT and the leading companies is widest. According to analysis by semiconductor research firm Nomad Semi, Samsung Electronics' HBM2 (second generation HBM) has more than 5,000 TSVs per die and SK hynix's HBM3 has more than 8,000, while CXMT's is understood to have only around 3,000. A smaller number of TSVs means sacrificing bandwidth (data processing speed) in exchange for lower process difficulty, yet even so CXMT's yields still fall far short of Samsung and SK hynix. TSV is a process that is challenging even for the industry leader: SK hynix itself publicly disclosed in 2024 that the yield of the standalone TSV process was only 40 to 60% at the time. On top of this, yield losses also occur in the back end (stacking and bonding) stage where the dies are actually stacked and joined. If even one of the eight dies is misaligned, if a microscopic void forms at a bonding interface, or if a layer warps during the thermocompression bonding process (warpage), the entire stack is scrapped. Because the number of possible failure points grows with each additional layer, the difficulty rises exponentially. Given that CXMT is already showing such poor yields at 8-High, some expect it to face even greater difficulties when moving to higher stacks such as 12-High. A semiconductor industry official explained, "The TSV process is an area that only stabilizes after years of accumulated wafer handling know how. Chinese companies have rapidly closed the gap in the fine process technology of DRAM itself, but back end know how such as TSV and bonding is difficult to catch up on in a short period." He added, "That said, Samsung Electronics also had initial HBM4 (sixth generation HBM) production yields below 60% in February this year and raised them to 80% within six months, so it is too early to declare CXMT's 25% yield a 'failure.'"

ネットで関わってくださっている皆さまへ 本日9時から、娘が約5時間に及ぶ顔の腫瘍摘出手術に臨みます。 ほんの数秒で構いません。 娘の手術が無事に終わること、腫瘍がきれいに取れること、顔に麻痺が残らないこと、そして傷跡が少しでもきれいに治ることを、一緒に祈っていただけないでしょうか。 現在は多形腺腫と診断されていますが、最終的な結果は摘出後の病理検査を待つことになります。 顔面神経の近くの手術ということもあり、麻痺が残る可能性や、大きな傷跡が残る可能性も説明されています。 親として今願うことは、 腫瘍がきれいに取れること。 最終的にも良性であること。 顔に麻痺が残らないこと。 そして傷跡が少しでもきれいに治ること。 普段ネットを通じて関わってくださっている皆さま、 今日だけ、少しだけ娘に力を貸してください。 よろしくお願いします。

She waited 63 years for the love of her life to come home. In 2013 at the age of 94 Clara Gantt finally received the remains of her husband Sergeant First Class Joseph Gantt. He was a United States Army medic who went missing during the Korean War. Joseph was captured in 1950 and died in a prisoner of war camp the following year. For more than six decades Clara lived without definitive answers yet she never stopped holding onto his memory. She chose not to remarry kept his medals nearby and always referred to herself as Mrs Gantt. When her husband’s flag draped casket finally arrived at Los Angeles International Airport Clara stood beside it in tears. She expressed gratitude for living long enough to welcome him home. After 63 years of waiting her husband had at last returned to her. Some love stories do not conclude with farewell. They endure through time and eventually find their way home.
