Abstract

本發明係提供一種包含亞胺基二乙酸及其衍生物之催化劑,該亞胺基二乙酸及其衍生物係作為具有催化活性之金屬離子之配位基。該催化劑可用於將金屬無電鍍覆於被覆及未被覆金屬之基板。

Description

含有亞胺基二乙酸及其衍生物之無電金屬化用催化劑
本發明係關於含有亞胺基二乙酸及其衍生物之用於無電金屬化之催化劑。更具體地,本發明係關於含有亞胺基二乙酸及其衍生物之用於無電金屬化之催化劑,其在儲存及無電金屬化之過程中係呈穩定狀態者。
傳統印刷電路板(printed circuit boards,以下簡稱PCB)包含經層壓之非導電性介電基板,該非導電性介電基板係有賴於經鑽孔及鍍覆之通孔(plated through holes,以下簡稱PTHs),以在電路板之相異側間或該板之內層間形成連結。於表面製備金屬塗覆時,無電鍍覆係習知之過程。介電表面之無電鍍覆須預先有催化劑之沉積(deposition)。於無電鍍覆之前,最常使用於催化或活化經層壓之非導電性介電基板區之方法,係以於酸性氯化物介質中之錫-鈀水性膠體(colloid)處理該基板。該膠體包含由錫(II)離子安定層包圍的金屬鈀芯。[SnCl3]-錯合物的外層 係作為表面安定基團,以避免懸浮液中膠體之凝聚(agglomeration)。
在活化製程中,以鈀為基底之膠體被吸附於絕緣基板(例如環氧化物或聚醯亞胺)上,以活化無電銅之沉積。理論上,於無電金屬沉積時,催化粒子在將還原劑中的電子移轉至該鍍覆浴中的金屬離子之路徑中扮演的角色為載體。雖然無電銅製程的施行係受許多因素影響,例如沉積溶液的組成以及配位基的選擇,此活化步驟係控制無電沉積之速率及機制之主要因素。數十年來,鈀/錫膠體已商用作為無電金屬沉積之活化劑,且其結構已被廣泛地研究。然而,其仍有諸如對空氣敏感及高成本等缺點有待改進。
雖然膠體鈀催化劑已具有諸多優點,其具有之缺點卻隨著製造PCB之品質提高而越來越明顯。近年來,隨著電子裝置尺寸的減小及性能的增加,電子線路的封裝密度已變高且隨後要求其在無電鍍覆後達到無缺陷。由於對可靠度之更大需求,需要開發出替代性的催化劑組成物。另外,膠體鈀催化劑之安定性也是一值得關注的部分。如上所述,該鈀/錫膠體係藉由錫(II)離子層安定化,且其相對離子(counter-ions)可防止鈀之凝集。該錫(II)離子易氧化成錫(IV),因此該膠體無法維持其膠體結構。此氧化反應係經由升溫及攪動而增進。若使錫(II)之濃度降至接近零,則鈀粒子將增大尺寸、凝聚及沉澱。
業經做出可觀之嘗試以尋找新的且較佳的 催化劑。舉例而言,因為鈀之高成本,較多的努力係朝向非鈀或雙金屬替代催化劑之開發。在過去,這些催化劑的問題包含其不具有足夠用於通孔鍍覆的活性或可靠度。此外,此等催化劑通常在靜置時會逐漸失去活性,且該活性的改變使得此等催化劑於商用上不可靠且不實際。因此,鈀/錫之替代催化劑仍有需求。
本發明所提供之一種方法,包括提供一催化劑,該催化劑係包括金屬離子錯合物及一種或多種具有式(I)結構之化合物或其鹽: 其中,R1、R2及R3可係相同或不同,且係氫或具有式(II)結構之部分: 其中,Y係氫、羧基、羥基、(C1-C3)烷氧基、經取代或未經取代的胺基、經取代或未經取代的芳基、經取代或未經取代的脂環、經取代或未經取代的雜脂環、經取代或未經取代的雜芳香環,Z係: n係0至15的整數,m係0至5的整數以及r係0至5的整數,其限制條件為在相同情況下R1、R2及R3中至少二者係式(II)結構且Y係羧基,以及R4、R5、R6、R7、R8、R9及R10可係相同或不同且係氫、羧基、羥基、直鏈或支鏈(C1-C5)烷基、直鏈或支鏈(C1-C5)羥烷基、經取代或未經取代的胺基或磺基;以及施用該催化劑至一基板;施用一還原劑至該催化劑;以及浸潤該基板至一金屬鍍覆浴中以無電鍍覆金屬於該基板上。
本發明另提供一種催化劑,本質上包括金屬離子以及一種或多種具有式(I)結構之化合物或其鹽: 其中,R1、R2及R3可係相同或不同,且係氫或具有式(II)結構之部分: 其中Y係氫、羧基、羥基、(C1-C3)烷氧基、經取代或未經取代的胺基、經取代或未經取代的芳基、經取代或未經取代的脂環、經取代或未經取代的雜脂環、經取代或未經取 代的雜芳香環,Z係n係0至15的整數,m係0至5的整數以及r係0至5的整數,其限制條件為在相同的情況R1、R2及R3中至少二者係式(II)結構且Y係羧基,以及R4、R5、R6、R7、R8、R9及R10可係相同或不同且係氫、羧基、羥基、直鏈或支鏈(C1-C5)烷基、直鏈或支鏈(C1-C5)羥烷基、經取代或未經取代的胺基或磺基。
該催化劑可被用於將金屬無電鍍覆於基板,包含介電材料之基板,且係在儲存及無電金屬鍍覆時皆呈穩定狀態之基板(因為相較於傳統的錫/鈀催化劑,其較不容易被氧化)。此等催化劑不需要以強酸來製備或維持其穩定性,從而相較於傳統的催化劑,係較不具腐蝕性。該催化劑之穩定性不需要藉由錫化合物,且可不含鹵素(鹵素可能具有腐蝕性)。該催化劑在印刷電路板製造時的導孔(via)及通孔(through-hole)裝填過程中可賦予良好的金屬覆蓋。
