Biden considering trip to Israel in the coming days, but travel isn't final, according to AP source_我的网站

A |     WASHINGTON -- President Joe Biden is considering a trip to Israel in the coming days, but nothing has been finalized, a senior administration official said Sunday.A trip would send the strongest message yet that the U.S. is behind Israel following the Oct. 7 attack by Hamas. The administration has already pledged military support, sending U.S. aircraft carriers to the region as well as aid. Officials have said they would ask Congress for upward of $2 billion in aid for both Israel and Ukraine.The official could not publicly discuss internal deliberations about the potential presidential travel and spoke to The Associated Press on condition of anonymity. THIS IS A BREAKING NEWS UPDATE. AP’s earlier story follows below.Egypt's president criticized Israel’s military operation in Gaza in a stern pushback Sunday to the United States as America's top diplomat extended his frenetic travels across the Mideast trying to prevent the war with Hamas from igniting a broader regional conflict.With an Israeli ground offensive looming, U.S. Secretary of State Antony Blinken reaffirmed in some of his strongest language to date that Washington would stand with Israel “today, tomorrow and every day” in a partnership of shared democratic values, but that Israel must take “every possible precaution to avoid harming civilians.” He leveled no direct public criticism of Israel or its bombing campaign that has killed civilians in Gaza.From Cairo, where President Abdel Fattah el-Sissi conveyed his criticism, Blinken went to Jordan and planned to return to Israel on Monday, carrying to Israeli leaders the feedback he received in a rush of meetings with leaders throughout the Arab world.His second visit to Israel in recent days will come amid heightening fears that a looming Israeli move into Gaza could spark a wider war with devastating humanitarian consequences, a growing concern for the Biden administration. And the death toll of U.S. citizens rose to 30, with 13 still missing.Egypt’s state-run media said el-Sissi told Blinken that Israel’s Gaza operation has exceeded “the right of self-defense” and turned into “a collective punishment."Blinken told reporters before leaving Egypt that “Israel has the right, indeed it has the obligation to defend itself against these attacks from Hamas and to try to do what it can to make sure that this never happens again." Mindful of the potential human cost in Gaza, Blinken said "the way that Israel does this matters. It needs to do it in a way that affirms the shared values that we have for human life and human dignity, taking every possible precaution to avoid harming civilians.’’Earlier Sunday, the envoy met with Saudi Crown Prince Mohammed bin Salman in Riyadh, talks that built upon earlier sessions with the leaders of the United Arab Emirates, Bahrain, Qatar, Jordan and the Palestinian Authority. Blinken said that what he heard in every meeting with Arab leaders “was a determination of shared view that we have to do everything possible to make sure this doesn’t spread to other places, a shared view to safeguard innocent lives, a shared view to get assistance to Palestinians in Gaza who need it and we’re working very much on that.”The White House also appointed David Satterfield, a former ambassador to Lebanon and Turkey, to lead U.S. efforts to get humanitarian assistance to “vulnerable people through the Middle East.” Satterfield was expected to arrive in Israel on Monday.From Washington, President Joe Biden’s national security adviser said the U.S. was not “making requests or demands of Israel with respect to its military operations.” Jake Sullivan, making the rounds of the Sunday TV news shows, said the administration was “simply stating our basic principles — the principles upon which this country is based and all democracies, including Israel, are based. It’s what makes us different from the terrorists, that in fact we respect civilian life.”He said the U.S. was not “not interfering in their military planning or trying to give them instructions or requests specific.” Sullivan said the U.S. is conveying the message in public and in private that “all military operations should be conducted consistent with law of war, that civilians should be protected, that civilians should have a real opportunity to get to safety” and have access to food, water, medicine and shelter.Those remarks marked a shift in the U.S. administration's comments in recent days as officials have heard concerns from Arab leaders about the consequences of what a humanitarian catastrophe resulting from an Israeli ground offensive would do not only to Palestinians but also in inflaming public opinions in Arab nations and potentially destabilizing relatively friendly countries.Sullivan also said the U.S. has been unable so far to get American citizens out of Gaza through Egypt’s Rafah crossing with Gaza. “It has been difficult to execute that operation to facilitate their passage out. … It’s a high priority,” acknowledging that “I’m not aware of anyone else being able to get out at this time.” The crossing was closed because of airstrikes early in the war. There are an estimated 500 Americans living in Gaza, but that number is imprecise, officials have said.U.S. officials have said the Arab reaction to Blinken’s message has been generally positive — acknowledging Israel has a right to respond to the Hamas attacks but expressing deep concern about the humanitarian situation in Gaza and unable to stay silent about the Palestinian civilian casualties that result. The Arab leaders have also said the current situation cannot be resolved without an Israeli-Palestinian peace deal that gives the Palestinians an independent state.Blinken made clear in Egypt that the U.S. will not waver in supporting Israel, saying, "We will stand with it today, tomorrow and every day and we’re doing that in word and also in deed.’’In his roughly hourlong meeting with Prince Mohammed at the de facto Saudi leader’s private farm outside Riyadh, Blinken “highlighted the United States’ unwavering focus on halting terrorist attacks by Hamas, securing the release of all hostages, and preventing the conflict from spreading,” the State Department said.“The two affirmed their shared commitment to protecting civilians and to advancing stability across the Middle East and beyond,” according to a department statement.The Saudi description of the meeting focused primarily on Palestinian civilians, echoing the sentiments that the other Arab leaders with whom Blinken has met. It said Saudi Arabia would object to the targeting of “civilians in any way or disrupt(ing) infrastructure and vital interests that affect their daily lives.”The prince “stressed the need to work to discuss ways to stop the military operations that claimed the lives of innocent people,“ the Saudi Press Agency said in a report about the meeting.___Associated Press writers Sam Magdy in Cairo, Colleen Long in Washington and Michelle L.

B | SemiAnalysis估计，仅2027年一年，NAND钼沉积设备的销售额就将超过10亿美元，并随着DRAM和逻辑芯片的跟进，到2030年增长至约20亿美元/年。

C | 　　受益格局方面，Lam Research（泛林集团）最先获益，TEL（东京电子）紧随其后；AMAT（应用材料）、ASMI（ASM国际）及Naura（北方华创）则更多受益于后续DRAM和逻辑芯片的转型浪潮。SemiAnalysis表示，完整的细分市场层面测算已纳入其前道设备（WFE）模型。　　钼渗透率在高层数NAND中提升，本质是为延续NAND单位Bit成本下降曲线。

D | 　　300层NAND主要在结构上升级，聚焦超高深宽比通道孔刻蚀、多次Stack堆叠、晶圆翘曲控制以及Overlay精度控制。　　375层乃至400层以后，材料亟需升级，因钨字线会因为字线间距通道孔缩小面临RC延迟快速恶化、WF残氟导致介质损伤、漏电失效率提升以及填充缺陷放大的问题。而钼凭借更低电阻率、无氟前驱体及无需阻隔层等优势，有望改善RC性能与器件可靠性，为字线和存储孔缩放提供工艺余量，从而延续高层数NAND的成本下降曲线。　　中银证券表示，SK海力士已完成375层3D NAND生产验证并计划2026年底量产，拟采用钼材料替代钨制作字线，继三星在286层第九代3D NAND中率先导入钼工艺后，两大存储龙头相继切换，钼替代钨趋势确立。　　然而，钼的材料加工更为复杂，因为必须以气体形式输送，且前驱物在室温下为固体，需要加热器以确保流动稳定性。　　基于此，300层以上3D NAND字线由钨切换为钼，并不是简单更换靶材或者更换气体材料，而是前驱体供给、ALD沉积腔体、刻蚀、清洗、尾气处理整套工艺链条的重构，原有钨CVD产线硬件无法直接复用，将直接推动晶圆厂资本开支上行，同时设备、特种材料、零部件均迎来变化。

E | 　　爱建证券表示，钼导入本质是一次全流程工艺重构，设备链受益有望沿“沉积及前驱体输送→CMP及清洗→刻蚀→量检测”路径传导，工艺难点由沉积向后处理环节延伸。其中——　　沉积：成熟的WF钨工艺，Mo沉积需重新建立高深宽比结构下的填充与缺陷控制工艺窗口，同时有望减少阻隔层使用，带动沉积设备及配套工艺升级；　　输送：Mo前驱体通常采用低挥发性固态源，与传统WF气态前驱体体系差异较大，需要新增气化装置、温控管路及精密供气系统，以保障前驱体稳定输送；　　CMP：Mo材料的氧化及表面化学特性不同于传统金属体系，需重新开发CMP研磨液和研磨垫，以满足平坦化、去除速率及缺陷控制要求；　　清洗：Mo导入后残留物及氧化物体系发生变化，高深宽比结构下金属残留和污染控制难度提升，有望推动相关湿法清洗设备及配套化学品验证导入；　　刻蚀环节则需重新建立适配钼材料的工艺窗口，且3DNAND层数持续提升下，刻蚀选择性、侧壁形貌控制及层间均匀性要求进一步提高，有望带动相关刻蚀设备升级需求；　　量检测：Mo量产还需新增膜厚均匀性、填充缺陷、金属残留及电学可靠性等监控项目，有望带动薄膜量测、缺陷检测及电性测试等设备需求增长。　　该机构称，NAND工艺迭代核心从单纯堆叠层数转向材料—设备—工艺协同创新，新材料导入将持续催生沉积、刻蚀、清洗等关键设备迭代升级，Mo字线导入将推动沉积、刻蚀、清洗等关键环节工艺升级，相关设备及零部件厂商有望受益。
