Abstract
本發明係關於適用於鈍化其上具有含鍺材料之微電子裝置上之該含鍺材料的組成物。
Description
本發明係關於一種用於鈍化微電子裝置表面上之含鍺材料的組成物及方法。
過去數十年來,積體電路中之特徵縮放導致半導體晶片上之功能單元的密度增加。舉例來說,縮小電晶體尺寸容許於晶片上納入增加數目的記憶體裝置,從而導致製得具有增加容量之產品。
在用於積體電路裝置之金屬氧化物半導體場效電晶體(MOSFET)的製造中,除矽之外的半傳導性結晶材料可能為有利的。一此種材料的實例為Ge,其提供相對於矽的許多潛在有利特徵,諸如,但不限於,高電荷載體(電洞)移動率、帶隙偏移、不同晶格常數、及與矽合金化形成SiGe之半傳導性二元合金的能力。
於新型電晶體設計中使用Ge的一個問題係目前針對這些年來積極縮放之矽FET所達成的極細特徵(例如,22nm及以下)現於Ge中難以達成,當以較不積極縮放的形式實施時通常使潛在基於材料的效能增益重新開始。舉例來說,MOSFET之效能強烈地受通道閘極介電質界面處之電活性缺陷影響。在具有矽通道之裝置中,可藉由於通道表面上謹慎形成薄氧化物來達成低界面陷阱密度(Dit;interface trap density)。對於具有鍺通道之裝置,不可藉由
此氧化過程輕易地達成低Dit。
本發明之一目的係提供用於鈍化微電子裝置上之含鍺表面的組成物。不受限於理論,據認為於含鍺表面上形成表面層(即鈍化)將抑制含鍺表面處之氧化及提供低界面陷阱密度。
本發明係關於一種用於鈍化包含含鍺表面之微電子裝置上之該含鍺表面的組成物及方法。
在一態樣中,描述一種鈍化微電子裝置表面上之含鍺材料的方法,該方法包括使包含含鍺材料之微電子裝置與鈍化組成物接觸,該鈍化組成物包含水及至少一種選自由α羥基酸、胺、唑類、羧酸、二醇、二硫化物、二硫醇、硒化物、亞硫酸鹽、硫醚、硫醇、硫基醇、硫二醇、鄰羥基硫酚、及其組合所組成之群之表面活性化合物。
本發明之其他態樣、特徵及具體例將可由隨後之揭示內容及隨附之申請專利範圍而更完整明瞭。

本發明之特徵及優點由以下論述的說明性實施例作更完整展示。
使用以下的六步驟氧化物移除過程來清潔具有0.02歐姆-公分(ohm-cm)之電阻率之摻雜鎵的p型鍺基板及具有0.04歐姆-公分之電阻率之n型鍺基板:
1. HCl/H2O2/H2O(100:1:500)沖洗20秒
2. DIW沖洗
3. NH4OH/H2O2/H2O(1:1:100)沖洗40秒
4. DIW沖洗
5. 4% HF沖洗1分鐘
6. DIW沖洗
然後使鍺基板暴露至包含硫化銨(1%水溶液)、硫基羥乙酸甲酯(1%水溶液)、3,6-二氧雜-1,8-辛烷二硫醇(1% DMSO溶液)中之一者的鈍化組成物持續5分鐘,接著進行DIW沖洗及氮氣乾燥。所有處理係於環境溫度下進行。使用來自625nm、700mW光電二極體的照明測量光致發光(PL)。積分的PL強度顯示於下表1中。表面缺陷導致非輻射復合及較低的PL強度。硫基羥乙酸甲酯之更高的PL強度係其較硫化銨對於表面鈍化更有效的證據。
使具有0.02歐姆-公分之電阻率之摻雜鎵的p型鍺基板接受以下過程:
1. 使用丙酮及接著異丙醇清洗
2. 暴露至包含硫化銨(1%水溶液)、3,3’-硫基二丙酸(1%水溶液)、2,2’-硫基二乙酸(1%水溶液)、3,6-二氧雜-1,8-辛烷二硫醇(1%
DMSO溶液)中之一者的鈍化組成物持續20分鐘
3. DI水沖洗
4. 氮氣吹乾
5. 10個脈衝的三甲基鋁(於ALD反應器中)
6. 使用三甲基鋁於250℃下進行Al2O3之100個循環的ALD
7. 於氮氣中進行450℃退火2分鐘
8. 通過遮罩進行Ni/Au頂部電極沉積
9. 與Ge基板底部形成Ti/Au歐姆接觸
10. 後金屬退火(300℃,於氮氣中30秒)
11. 測量電容相對電壓。
電容相對電壓的測量係在介於100Hz與1MHz間的25個頻率下以介於2.25與-2.25伏特之間的閘極電壓進行。將此等測量模型化以得到界面狀態之密度。以下給出若干配方的結果。3,3’-硫基二丙酸顯示Dit降低且無Q-時間與Dit之較少增加及24小時的Q-時間。2,2’-硫基二乙酸顯示較硫化銨低的Dit與24小時的佇列時間。對於p型Ge,3,6-二氧雜-1,8-辛烷二硫醇及硫基羥乙酸甲酯顯示較硫化銨低的頻率分散與相當的Dit及遲滯。
雖然本發明已參照本發明之特定態樣、特徵及說明具體例說明於文中,但當明瞭本發明之效用並不因此受限,而係可延伸至涵蓋熟悉本發明領域人士基於文中揭示內容所可明白的許多其他變化、修改及替代具體例。因此,後文所主張之發明意欲經廣泛解釋及詮釋為包括在其精神及範疇內的所有此等變化、修改及替代具體例。
