Abstract
公開了一種用於拋光介電襯底之化學機械拋光組成物,其包含用聚烷氧基化的有機矽烷穩定的膠體二氧化矽磨料顆粒。
Description
本發明涉及用於拋光介電襯底的在鹼性pH下具有穩定的膠體二氧化矽磨料顆粒之化學機械拋光組成物。更具體地,本發明涉及在鹼性pH下具有穩定的膠體二氧化矽磨料顆粒之化學機械拋光組成物,其中該穩定的膠體二氧化矽磨料顆粒用聚烷氧基化的有機矽烷穩定。
在積體電路以及其他電子裝置的製造中,將多層導電材料、半導電材料以及介電材料沈積在半導體晶圓的表面上或從半導體晶圓的表面上移除。可以藉由多種沈積技術來沈積導電材料、半導電材料以及介電材料的薄層。在現代加工中常見的沈積技術包括物理氣相沈積(PVD)(也稱為濺射)、化學氣相沈積(CVD)、電漿增強的化學氣相沈積(PECVD)、以及電化學電鍍(ECP)。
隨著材料層被依次地沈積和移除,晶圓的最上表面變成非平面的。因為後續的半導體加工(例如金屬化)要求晶圓具有平坦的表面,所以需要對晶圓進行平坦化。平坦化在移除不希望的表面形貌和表面缺陷中是有用的。
化學機械平坦化、或化學機械拋光(CMP)係用於將襯底(諸如半導體晶圓)平坦化之常見技術。在常規的CMP中,晶圓被安裝在托架組件上並且被定位成與CMP設備中的拋光墊接觸。托架組件向晶圓提供可控的壓力,從而將晶圓壓靠在拋光墊上。該墊藉由外部驅動力相對於晶圓移動(例如旋轉)。與此同時,在晶圓與拋光墊之間提供拋光組成物(「漿料」)或其他拋光液。因此,藉由墊表面和漿料的化學和機械作用將晶圓表面拋光並且使其成為平面。
某些先進裝置設計要求在較低的使用點(POU)磨料wt%下提供增強的中間層介電(ILD)移除效率的鹼性拋光組成物。此類ILD包括氧化矽和氮化矽。一種方法係增加電解質濃度,從而增加電導率;然而,增加電解質濃度導致膠體二氧化矽磨料顆粒的不穩定性。增加離子濃度導致膠體二氧化矽磨料顆粒上的較少的表面電荷,並致使較小的顆粒排斥,這係穩定顆粒的主要力。
因此,需要在鹼性pH下展現出改進的膠體二氧化矽磨料顆粒的穩定性的拋光組成物和拋光方法。
本發明涉及一種化學機械拋光組成物,其包含以下項作為初始組分:
水;
膠體二氧化矽磨料顆粒;
具有式 (I) 之聚烷氧基有機矽烷:(I)
其中R選自(C1
-C4
)烷基;R1
選自由氫、(C1
-C4
)烷基和R2
C(O)-組成之群組,其中R2
選自由氫和(C1
-C4
)烷基組成之群組;並且n係1至12的整數;
pH > 7;以及
視需要鹼金屬或銨的無機鹽或其混合物;以及
視需要pH調節劑。
本發明還包括一種用於對襯底進行化學機械拋光之方法,該方法包括:
提供襯底,其中該襯底包括氧化矽、氮化矽和多晶矽中的至少一種;
提供化學機械拋光組成物,其包含以下項作為初始組分:
水;
膠體二氧化矽磨料顆粒;
具有式 (I) 之聚烷氧基有機矽烷:(I)
其中R選自(C1
-C4
)烷基;R1
選自由氫、(C1
-C4
)烷基和R2
C(O)-組成之群組,其中R2
選自由氫和(C1
-C4
)烷基組成之群組;並且n係1至12的整數;
pH > 7;以及
視需要鹼金屬或銨的無機鹽或其混合物;以及
視需要pH調節劑;
提供具有拋光表面的化學機械拋光墊;
用0.69至69 kPa的下壓力在該化學機械拋光墊的拋光表面與該襯底之間的介面處產生動態接觸;以及
在該化學機械拋光墊與該襯底之間的介面處或介面附近將該化學機械拋光組成物分配到該化學機械拋光墊上;
其中該襯底被拋光;並且其中,將該氧化矽、氮化矽、多晶矽或其組合中的至少一些從該襯底上移除。
本發明的化學機械拋光組成物的聚烷氧基有機矽烷化合物在鹼性pH下使膠體二氧化矽磨料顆粒穩定,使得該膠體二氧化矽磨料顆粒基本上不附聚。此種附聚被該聚烷氧基有機矽烷化合物抑制,該化合物共價地改性該膠體二氧化矽磨料顆粒的表面以提供位阻保護。即使在相對高濃度的無機鹽下也實現此種位阻保護。

術語「化學機械拋光」或「CMP」係指單獨地憑藉化學和機械力來拋光襯底的製程,並且其區別於其中向襯底施加電偏壓的電化學-機械拋光(ECMP)。術語「TEOS」意指由原矽酸四乙酯(Si(OC2

)分解而形成的氧化矽。在通篇說明書中,術語「組成物」和「漿料」可互換使用。術語「鹵離子」意指氯離子、溴離子、氟離子和碘離子。術語「一個/種(a/an)」係指單數和複數二者。除非另外指出,否則所有百分比均為按重量計的。所有數值範圍都是包含端值的,並且可按任何順序組合,除了此數值範圍被限制為加起來最高達100%係合乎邏輯的情況之外。
