Description
本發明係關於一種用於錫及錫合金沈積之自催化電鍍浴組合物,及一種應用該自催化電鍍浴組合物之方法。本發明係關於製造諸如印刷電路板、IC基板及半導體晶圓之電子零件。
於諸如印刷電路板、IC基板及半導體晶圓之電子零件上的錫及錫合金層在稍後該等電子零件的製造步驟中用作可焊接及可黏結的修飾面層。
錫及錫合金層通常沈積於金屬接觸區域上,諸如接觸焊墊及凸塊結構。接觸區域通常由銅或銅合金製成。在可電接觸該等接觸焊墊用於沈積錫及錫合金層的情況下,該等層係藉由習知電鍍方法沈積。然而,在許多情況下無法電接觸個別接觸區域。在該等情況下需要應用無電電鍍方法。在工業中用於無電電鍍錫及錫合金層之所選方法為浸鍍。浸沒型電鍍之主要缺陷為錫或錫合金沈積物之厚度有限。浸鍍係基於錫離子與待電鍍之金屬銅接觸區域之間的交換。浸沒型電鍍錫或錫合金層時,隨著錫層厚度增加,沈積速率顯著降低,因為生長之Sn層防礙Sn對Cu之交換。因此對於許多實際應用,使用浸沒方法使錫層沈積超過1.0 μm之厚度可能花費太多時間。
在需要更厚的錫層或錫合金層的情形中,需要使用自催化型無電電鍍方法。用於自催化電鍍錫或錫合金之電鍍浴
組合物包含還原劑。
專利文獻US 5,364,459揭示用於自催化沈積錫之無電電鍍浴組合物,該等浴組合物包含作為還原劑之Ti3+離子、諸如檸檬酸或EDTA之鹽的錯合劑、Sn2+及Pb2+離子及作為pH值調節劑之碳酸根離子。
專利文獻US 5,360,471揭示用於焊接沈積之無電電鍍浴組合物,該等浴組合物包含作為還原劑之Ti3+離子、諸如檸檬酸及EDTA之鹽的錯合劑、Sn2+離子及作為pH值調節劑之氨。
「Autocatalytische Zinnabscheidung」(「Autocatyltic Tin Deposition」),M.E.Warwick,B.F.Müller,Metall,第36卷,1982,第955至958頁揭示由作為還原劑之TiCl3、作為錯合劑之檸檬酸及EDTA之鹽、乙酸鈉、Sn2+離子、苯磺酸及作為pH值調節劑之氨組成之自催化錫電鍍浴。
WO 2009/157334 A1中揭示用於沈積錫之自催化電鍍浴,其包含水溶性錫化合物、水溶性鈦化合物、有機錯合劑及選自由硫醇及硫化物組成之群的有機硫化合物。
WO 2008/081637 A1中揭示包含水溶性錫化合物、水溶性鈦化合物及含有三價磷之有機錯合劑之自催化錫電鍍浴。
此項技術中已知之自催化錫電鍍浴組合物在防止不希望的錫析出與實際應用所需之足夠沈積速度之間無法取得平衡。
因此本發明之目標為提供一種用於沈積錫及錫合金之自催化電鍍浴組合物,其對於不希望的錫析出或浴組分沈澱保持穩定,且同時提供在製造諸如印刷電路板、IC基板之電子零件及對半導體晶圓進行金屬化的方法中允許使用該自催化電鍍浴組合物的沈積速度。
