在一個實施例中,方法係在升高之溫度(例如約20℃至約100℃)下實施。
式(I)化合物亦可藉由利用下式之起始材料來製備: , 即,通式A 2MO 4之化合物,其中M選自鉻、鉬或鎢,且A選自I族及II族金屬或銨陽離子。該等陽離子之實例包括Li +、Na +、K +、NH 4 +、烷基銨化合物及諸如此類。該等化合物可在式L 1及/或L 2之化合物之存在下與HX類似地反應,以獲得期望之前驅化合物。
本發明方法提供某些化合物,其繼而可用於將某些VI族金屬氣相沈積於各種基板、包括微電子半導體裝置基板上。因此,在另一態樣中,本發明提供在基板上形成材料之方法,其包含使基板與式(I)之化合物接觸 (I), 其中M選自鉬、鉻及鎢,X選自氟、氯、溴及碘,且每一L 1及L 2相同或不同且構成: (i) 與M配位之單齒烴基配體,或 (ii) 一起形成與M配位之二齒烴基配體; 在氣相沈積條件下將含鉬、鉻或鎢之材料沈積於基板上。
用於本發明沈積方法中之基板可為任何適宜類型,且可包含(例如)半導體裝置基板,例如矽基板、二氧化矽基板或其他基於矽之基板。在各個實施例中,基板可包含一或多種金屬或電介質基板,例如Co、Cu、Al、W、WN、WC、 TiN、Mo、MoC、SiO 2、W、SiN、、WCN、Al 2O 3、AlN、ZrO2、HfO 2、SiO 2、氧化鑭(La 2O 3)、氮化鉭(TaN)、氧化釕(RuO 2)、氧化銥(IrO 2)、氧化鈮(Nb 2O 3)及氧化釔(Y 2O 3)。
在某些實施例中,例如在氧化物基板(例如二氧化矽)或另一選擇矽或多晶矽基板之情形中,基板可經處理或製作以在其上包括用於後續沈積材料之障壁層(例如氮化鈦)。
在一個實施例中,沈積於基板表面上之含鉬、鉻或鎢之層可係藉由(例如)脈衝化學氣相沈積(CVD)或原子層沈積(ALD)或其他氣相沈積技術形成,而不需預先形成成核層且因此直接利用源自式(I)化合物之蒸氣。各別式(I)蒸氣接觸步驟可交替並重複地實施所期望之循環次數,以形成期望厚度之鉬、鉻或鎢膜。在各個實施例中,基板(例如氮化鈦)層與該蒸氣之接觸係在低至350℃且在其他實施例中在300℃至750℃範圍內之溫度下實施。
利用源自式(I)化合物之蒸氣,含鉬、鉻或鎢之材料可直接沈積於基板上,以形成元素鉬、鉻或鎢或其相應氧化物之塊體沈積物。H 2之濃度對於金屬或氧化物之形成至關重要,此乃因金屬形成需要大於四莫耳當量或過量之H 2。少於四(4)莫耳當量之H 2將導致形成不同量之該等金屬之氧化物,且因此將需要進一步暴露於H 2以還原由此形成之金屬氧化物。
在各個實施例中,含鉬、鉻或鎢之材料係在300℃至750℃範圍內之溫度下沈積於基板表面上。可實施該方法,以使得氣相沈積條件引起元素鉬、鉻或鎢作為含金屬材料於基板上之沈積。氣相沈積條件可具有任何適宜特徵,且可包含(例如)氫氣或其他還原性氣體之存在,以在基板上形成元素鉬、鉻或鎢之塊體層。
更一般而言,根據本揭示內容,在基板上形成含鉬、鉻或鎢之材料之廣泛方法可包含包括存在氫氣或其他還原性氣體之氣相沈積條件。含鉬、鉻或鎢之材料可在存在或不存在氫氣之情形中沈積於障壁層或表面上。舉例而言,障壁層可由氮化鈦構成,且氮化鈦層可在氫氣之存在下與源自式(I)化合物之蒸氣接觸。
在另一實施例中,在使用式(I)化合物作為沈積金屬氧化物薄膜(例如MoO 2、WO 3及Cr 2O 3)之手段時,可將氧化共反應物(例如氧)添加至方法中。
應瞭解,本發明可以許多替代方式並在眾多種製程條件下實施。本發明方法可在(例如)在基板上製造半導體裝置之製程中實施。半導體裝置可為任何適宜類型,且可包含例如DRAM裝置、3-D NAND裝置或其他裝置或裝置積體結構。在各個實施例中,基板可包含含鉬材料沈積於其中之通孔。舉例而言,裝置可具有在10:1至40:1範圍內之深度對橫向尺寸之縱橫比。在其他實施例中,裝置可為用於平板顯示器或行動裝置中之膜。
根據本發明,沈積含鉬材料之製程化學可包括藉由以下反應沈積元素鉬Mo(0):2 MO 2Cl 2[(L 1)(L 2)] + 6H 2→ 2M (其中M = 鉬、鉻或鎢) + 4HCl + 4H 2O。根據本發明方法沈積之含鉬、鉻或鎢之材料(M)可藉由任何適當評估指標及參數來表徵,例如,含鉬、鉻或鎢之材料之沈積速率、所沈積含鉬、鉻或鎢之材料之膜電阻率、所沈積含鉬、鉻或鎢之材料之膜形態、所沈積含鉬、鉻或鎢之材料之膜應力、材料之階梯覆蓋率以及適當處理條件之製程窗或製程包絡。可採用任何適當評估指標及參數來表徵所沈積之材料並將其與具體製程條件相關聯,以能夠大量生產相應半導體產品。有利地,本發明方法能夠將高純度鉬、鉻或鎢之膜沈積於半導體裝置上。因此,在另一態樣中,本發明提供具有沈積於其上之鉬膜之半導體裝置,其中該膜包含大於99%鉬、鉻或鎢。
在某些實施例中,本發明係關於在基板上形成含鉬、鉻或鎢之材料之方法,其包含藉由化學氣相沈積(CVD)製程利用前驅物式(I)化合物將鉬、鉻或鎢沈積於基板表面上,以在該基板上產生含鉬、鉻或鎢之材料。
該等製程可以如本文多方面闡述之任何適宜方式實施。在具體實施例中,該方法可利用包含化學氣相沈積(例如,脈衝化學氣相沈積)之氣相沈積製程實施。該方法可經實施,以使得所得含鉬、鉻或鎢之材料基本上由元素鉬、鉻或鎢構成,且在各個實施例中,鉬、鉻或鎢可在氫氣或其他適宜還原性氣體之存在下沈積於基板表面上。在本發明之其他實施例中,式(I)之前驅物及還原性氣體可相繼以脈衝方式輸送,以脈衝方式沈積鉬膜,其中脈衝序列針對膜保形性及膜電阻率經最佳化。該方法可在半導體裝置產品(例如DRAM裝置、或3-D NAND、邏輯裝置、平板顯示器或IC封裝組件)之製造中實施。
通常,本發明用於在基板上形成含鉬、鉻或鎢之材料之方法可經實施以達成含鉬、鉻或鎢之材料以高程度之階梯覆蓋率(例如,在約75%至約100%範圍內之階梯覆蓋率)之沈積。
本發明可藉由其較佳實施例之下列實例進一步說明,但應理解,除非另外特定指出,否則包括該等實例僅用於說明之目的且並非意欲限制本發明之範圍。
試驗部分使用以下一般程序,可製備式(I)化合物:
合成程序 1 .將MoO 3(20.0 g, 138 mmol)加載於配備有磁力攪拌棒之500 mL圓底燒瓶中。將HCl (200 mL, 37%)直接添加至MoO 3,反應燒瓶裝備有水冷式冷凝器(5℃),並使用油浴將所得淺綠色懸浮液加熱至接近回流(95℃)。約2小時後,反應呈現為澄清淺綠色溶液。將反應冷卻至室溫,然後置於冰浴中。此時,將DME (50 mL)直接添加至經冷卻之溶液並使反應升溫至室溫並攪拌過夜。第二天早晨,將淺綠色溶液傾倒於1L分液漏斗中並用DCM (2 x 200 mL)萃取。將有機層合併,使用MgSO 4乾燥,過濾,置於配備有磁力攪拌棒之1L圓底燒瓶,並在減壓下去除溶劑,以獲得呈灰白色固體之MoO 2Cl 2(二甲氧基乙烷)。質量= 12.68g,產率 = 31.8%。產物可經真空昇華(80℃,在25毫托(mTorr)下)純化。 1H NMR (400 MHz, C 6D 6, 298K): δ 3.29 (s, 6H);2.78 (s, 4H) ppm。 13C{1H} NMR (100 MHz, C 6D 6, 298K): δ 70.68, 64.13 ppm。
合成程序 2 通式A 2MO 4,其中M = 鉻、鉬或鎢且A = 鋰、鈉或鉀。 此處,一般合成程序及後處理極類似於程序1號 , 即,通式A 2MO 4之化合物,其中M係選自鉻、鉬或鎢,且A係選自I及II族金屬或銨陽離子。實例包括Li +、Na +、K +、NH 4 +、烷基銨化合物及諸如此類。
合成程序 3 可利用配體取代以合成式(I)化合物。舉例而言,可使用上文程序1號製備MoO 2Cl 2(N,N-二甲基甲醯胺) 2錯合物,且然後N,N-二甲基甲醯胺配體經由溶劑分解來取代二甲氧基乙烷以產生MoO 2Cl 2(二甲氧基乙烷)。
