凱澤金屬多維度對比半導(dǎo)體芯片與電子器件用鈦鋁靶的異同

鈦鋁靶是以鈦鋁金屬間化合物為核心的濺射靶材,通過物理氣相沉積(PVD)形成高硬度、耐腐蝕的功能薄膜(如TiAlN、TiAlO),其核心優(yōu)勢在于高純度(半導(dǎo)體級達(dá)4N5以上)、可調(diào)成分(鈦鋁比例優(yōu)化硬度/導(dǎo)電性平衡)及高溫穩(wěn)定性。在半導(dǎo)體領(lǐng)域,高純鈦鋁靶用于28nm以下制程的導(dǎo)電/阻擋層,抑制銅擴(kuò)散并提升芯片可靠性;在硬質(zhì)涂層領(lǐng)域,氮化鈦鋁(TiAlN)顯著延長刀具壽命,適配高速加工需求;高頻電子器件中,其低電阻特性降低信號損耗,替代傳統(tǒng)ITO材料。未來發(fā)展趨勢聚焦高純化(5N級)、放電等離子燒結(jié)(SPS)工藝優(yōu)化成分均勻性,以及適配第三代半導(dǎo)體(氮化鎵、碳化硅)高溫高功率場景,成為先進(jìn)芯片制造、高頻電子及耐候性涂層的核心材料。以下是凱澤金屬根據(jù)半導(dǎo)體芯片、電子器件用鈦鋁靶的定義、性能、標(biāo)準(zhǔn)、應(yīng)用等多維度,整理的相關(guān)數(shù)據(jù)表:
