2026年第二季,全球前十大晶圓代工廠營收達534.9億美元,季增11.5%,創歷史新高。台積電營收突破400億美元,市占率升至72.5%,貢獻產業新增產值的78.7%。三星成長趨緩,市占率降至5.9%;中芯國際營收季增20%,市占率升至5.4%。中國三大代工廠合計市占率約為8.5%,低於歷史峰值。產業集中度持續提升,前五大廠商佔市場90.9%。

AI-generated summary

Why It Matters

全球晶圓代工產業受AI與HPC需求擴張及消費性電子備貨雙重驅動,持續成長。台積電以技術領先優勢持續擴大市占率,而中國代工廠雖有成長,但整體市占率未能回升至歷史高點。

2026年第二季,全球晶圓代工產業在人工智慧(AI)、高效能運算(HPC)需求持續擴張,以及消費性電子供應鏈提前備貨的雙重帶動下,延續強勁成長動能。

根據集邦科技(TrendForce)統計,全球前十大晶圓代工廠第二季合計營收達534.9億美元,較前一季成長11.5%,再創歷史新高,增幅亦明顯高於第一季的3.7%。

本季前十大業者營收全數較上季成長。主要動能來自AI與HPC處理器使用的先進製程持續供不應求,以及電源管理晶片(PMIC)、功率分立元件等AI周邊晶片需求升溫。電視、個人電腦與筆記型電腦供應鏈提前備貨,也使部分成熟製程產能進一步吃緊。

然而,本季成長成果仍高度集中於少數領先業者。台積電單季新增營收占前十大業者新增產值近八成,反映全球晶圓代工市場集中度持續處於高檔。

台積電營收突破400億美元,市占率升至72.5%

台積電2026年第二季營收達401.98億美元,較上季成長12.1%,增幅高於整體產業平均水準。

若以絕對金額計算,台積電單季營收增加約43.4億美元,而全球前十大晶圓代工廠總營收增加約55.2億美元,相當於本季產業新增產值的78.7%由台積電貢獻。

台積電全球晶圓代工市占率由第一季的72.3%進一步升至72.5%,再創新高;與2025年同期的70.2%相比,增加2.3個百分點。

三星成長趨緩,中芯國際快速逼近

排名第二的三星,第二季營收為32.6億美元,較上季成長1.8%。雖然包括高頻寬記憶體(HBM)基礎裸晶在內的先進製程新訂單逐步放量,5/4奈米及更先進製程的代工價格也有所調升,但整體成長速度明顯落後同業,市占率由第一季的6.5%降至5.9%。

三星與台積電的市占率差距已擴大至66.6個百分點,全球晶圓代工市場「一強主導」的競爭格局更為鮮明。

中芯國際則維持全球第三大晶圓代工廠地位。第二季營收季增20.0%,首度突破30億美元,達30.06億美元,為前十大業者中成長幅度最高者;市占率亦由5.1%升至5.4%。

中芯國際與三星的市占率差距,已由第一季的1.4個百分點縮小至0.5個百分點,顯示全球第二與第三大晶圓代工廠之間的競爭日益激烈。

其他主要晶圓代工廠均維持成長

聯電維持第四名,第二季營收達21.75億美元,季增12.7%,市占率持平於3.9%。

格羅方德(GlobalFoundries)排名第五,營收為17.86億美元,季增9.3%,惟市占率由3.3%微降至3.2%。

華虹集團排名第六,第二季營收達12.74億美元,季增3.5%,市占率由2.5%降至2.3%。

高塔半導體(Tower)排名第七,營收為4.6億美元,季增11.2%。

第八至第十名方面,世界先進(VIS)營收季增13.8%至4.51億美元,重返第八名;晶合集成(Nexchip)營收季增6.4%至4.47億美元,退居第九;力積電(PSMC)晶圓代工營收季增11.9%至4.32億美元,排名第十。

中國主要晶圓代工廠占比略有回升,但仍低於高峰

觀察中國三大晶圓代工企業中芯國際、華虹集團與晶合集成,三家公司2026年第二季合計市占率約為8.5%,其中中芯國際占5.4%、華虹集團占2.3%、晶合集成占0.8%。

相較於第一季的8.4%,三家業者合計市占率小幅回升,主要由中芯國際單季營收成長20%所帶動。

不過,8.5%的占比仍低於2025年全年的8.8%,更明顯低於2022年約9.7%的高點。這顯示,儘管中國晶圓代工業者近年大規模擴充成熟製程產能,但在全球市場快速成長、新增需求集中於先進製程的情況下,相關產能擴張尚未有效轉化為全球市占率的提升。

市場集中度維持高檔,龍頭效應持續擴大

從產業結構來看,2026年第二季全球晶圓代工市場延續高度集中趨勢。前十大晶圓代工廠合計掌握96.5%的市場,其中台積電單一企業即占72.5%。

若合計台積電、三星與中芯國際前三大業者,其市占率達83.8%;前五大業者合計更掌握90.9%的市場。

與一年前相比,台積電市占率增加2.3個百分點,中芯國際微增0.3個百分點;三星減少1.4個百分點,格羅方德減少0.7個百分點,聯電減少0.5個百分點。

整體而言,全球晶圓代工市場的新增需求正持續向技術領先業者集中。隨著AI與HPC應用加速發展,先進製程需求日益成為產業成長的主要驅動力,台積電的技術與規模優勢也進一步轉化為更高的市場占有率。

從2023Q2至2026Q2,全球前十大晶圓代工市場延續高度集中趨勢。(作者提供)
