日本幾乎壟斷了高階光阻市場，控制著全球70%以上的市佔率。出口和供應鏈中斷引發了中國半導體產業的擔憂。由於雙方都實施了重疊的出口限制，緊張局勢不斷升級，給試圖擴大先進晶片製造規模的中國晶圓代工廠帶來了巨大壓力。
想要更深入地了解在當前地緣政治緊張局勢下，中國如何努力實現半導體自主，請觀看這段關於國內供應鏈變化的影片：9:16 中國限制從日本進口材料，日本採取報復措施…三立商事iNEWS YouTube · 2026年6月29日 供應問題的關鍵驅動因素：地緣和出口管制：地緣和東京的政治範圍。儘管日本對光刻機備件和關鍵材料實施了嚴格的審查，但這導致中國企業的交貨週期延長，技術支援減少。
市場主導：信越化學工業株式會社和東京櫻工業株式會社等公司主導全球供應。高端光阻由於保存期限短，難以儲備。如果出貨延遲或減少，中芯國際等中國晶圓廠很容易受到生產瓶頸的影響。
更廣泛的全球衝擊：全球供應受到更廣泛的地緣政治動盪（例如來自中東的石腦油供應限制）的影響，進一步加劇了半導體供應鏈的壓力。
中國的策略與國內替代方案：加速國產化：為了減少對日本光阻的依賴，北京正加速推進國內光阻的自給自足。徐州博克化學和北京肯普微電子等公司正在擴大量產能力。
驗證障礙：儘管中國發展迅速，但將光阻從實驗室研發到實際矽片生產線應用可能需要一到三年時間，這使得這一轉變成為一項極具挑戰性的長期項目。
採購替代方案：中國半導體企業正在探索從韓國供應商進口材料，這些供應商在2019年日韓貿易爭端期間已經實現了相當程度的本地化。
您想了解更多關於以下方面的資訊：在中國營運的具體光阻供應商？ ArF、KrF和EUV光阻的取得途徑有何不同？韓國的替代方案在當前市場中扮演什麼角色？請告訴我您希望如何縮小訊息範圍。

日本四大光刻膠巨頭，竟然傳出全面停止接收中國高端光刻膠新訂單，甚至撤回駐廠技術工程師。
- Geopolitics and Export Controls: Escalating diplomatic disputes between Tokyo and Beijing have led to expanded export controls on dual-use goods. While Japan has implemented stringent reviews of lithography spare parts and critical materials, this has translated into stretched delivery timelines and reduced technical support for Chinese firms. [1, 2, 3]
- Market Dominance: Companies like Shin-Etsu Chemical and Tokyo Ohka Kogyo dominate global supply. High-end photoresists cannot easily be stockpiled due to short shelf lives. This leaves Chinese fabs, such as SMIC, vulnerable to production bottlenecks if shipments are delayed or reduced. [1, 2]
- Broader Global Shocks: Global supply has been strained by broader geopolitical disruptions (such as naphtha constraints originating from the Middle East), adding further strain to the semiconductor supply chain. [1, 2]
- Accelerated Localization: To offset the reliance on Japanese photoresists, Beijing is fast-tracking domestic self-sufficiency. Firms like Xuzhou B&C Chemical and Beijing Kempur Microelectronics are expanding mass production capabilities. [1, 2, 3, 4]
- Verification Roadblocks: Though China is rapidly advancing, moving a photoresist from the lab to a working silicon line can take from one to three years, making the shift a highly challenging and long-term project. [1]
- Sourcing Alternatives: Chinese semiconductor players are exploring importing materials from South Korean suppliers, which already achieved considerable localization during the 2019 Japan-Korea trade disputes. [1, 2]
