改善半導體元件效能的方法通常是藉由縮小積體電路的幾何 尺=’上述之結果可以使單位晶粒(perdie)成本下降,並同時改 善半導體兀件之某些方面的效能。連接積體電路與其他電路之間 或積體電路與系統元件之間的金屬連接(metal c〇nnecti〇n)變得 相對地重要,且隨著積體電路的更加微型化,對於線路效能的負 面影響也隨之增加。當金屬内連線之寄生電容(parasitic capacitance)與電阻增加,將意味著晶片效能的下降。其中,最值 得關切的是沿著電源匯流排(powerbuses)與接地匯流排(浮〇1111(1 buses)之間的壓降(v〇itage drop),以及關鍵訊號路徑之電阻電容 延遲(RC delay)。為了降低電阻,若是使用寬金屬線,將導致這 些寬金屬線的寄生電容升高。為了解決這個問題,便發展使用低 電阻之金屬(例如銅)做為導線,並使用低介電常數(1〇w_k)之 介電材料於訊號線之間。從1C連接金屬歷史的觀點來看,濺鍍鋁 從60年代後巳成為ic連接金屬材料之主流。薄膜鋁經由濺鍍來 覆蓋整片晶圓’接下來以黃光微影製程及乾蝕刻或濕蝕刻的製程 將鋁金屬圖案化。就成本及濺鍍應力考量而言’要製作厚度超過2 μιη之紹金屬線路技術是很困難且成本很昂貴。大約在1995年, 鑲嵌銅(Damascene)成為另一種可用於ic連接之金屬。就鑲嵌 (Damascene)銅而言,在絕緣層圖案化之後,藉由電鍍可以形成銅 層及藉由化學機械研磨(CMP)可以將位於絕緣層開口外之銅層除 掉’將銅金屬連線形成於絕緣層開孔中。在整片晶圓上電鐘厚金 6 1308785 大的應力’且鑲嵌銅(Damaseene)的厚度通常是由絕緣層 二,定’故絕緣層-般如,氧化物,由於應力及成本 ^ :法提供太厚之厚度’也就是說要形成厚度超過2师之銅金 屬連線,在技術上有其困難且成本昂貴。 —美國專利公告第5,212,4G3號⑼—碗)揭露—種形成線路連 線的方法,其巾内部及外狀線路連_軸在·^上之線 路基底内,邏輯線路的設計會取決於、線路連線的長度。A method for improving the performance of a semiconductor device is generally to reduce the cost per die (die) by reducing the geometry of the integrated circuit = 'the above results, while improving the performance of some aspects of the semiconductor device. The metal connection (metal c〇nnecti〇n) between the integrated circuit and other circuits or between the integrated circuit and the system components becomes relatively important, and with the further miniaturization of the integrated circuits, for line performance The negative impact also increases. When the parasitic capacitance and resistance of the metal interconnects increase, it will mean a decrease in the performance of the wafer. Among them, the most concern is the voltage drop (v〇itage drop) between the power bus and the ground bus (the floating 1111 (1 buses), and the resistance and capacitance delay of the key signal path (RC delay) In order to reduce the resistance, if a wide metal wire is used, the parasitic capacitance of these wide metal wires will increase. To solve this problem, a low-resistance metal (such as copper) is used as a wire, and a low dielectric constant is used. The dielectric material of (1〇w_k) is between the signal lines. From the point of view of the history of 1C connection metal, the aluminum sputter has become the mainstream of ic connection metal materials since the 1960s. The film aluminum covers the whole film by sputtering. The wafer's next process is to pattern aluminum metal in a yellow lithography process and a dry or wet etch process. In terms of cost and sputtering stress considerations, it is difficult and costly to produce a metal circuit with a thickness of more than 2 μm. Expensive. In about 1995, Damascene became another metal that can be used for ic bonding. In the case of damascene copper, after patterning the insulating layer, it can be shaped by electroplating. The copper layer and by chemical mechanical polishing (CMP) can remove the copper layer outside the opening of the insulating layer. The copper metal wire is formed in the opening of the insulating layer. The electric clock is thick on the whole wafer and the gold is 6 1308785. 'And the thickness of the inlaid copper (Damaseene) is usually determined by the insulating layer two, so the insulating layer - like oxide, due to stress and cost ^: method provides too thick thickness 'that is to form a thickness of more than 2 division The copper metal connection is technically difficult and costly. - US Patent Publication No. 5,212, 4G3 (9) - Bowl) discloses a method of forming a line connection, in which the inside and outside of the towel are connected In the circuit substrate on the circuit board, the design of the logic circuit depends on the length of the line connection.

A semiconductor substrate 10 has a transistor or an electronic component formed of other materials such as polysilicon. A thin film dielectric layer 12 is formed on the surface of the semiconductor substrate 1 and covers these electronic components. The source (S〇urce) and the drain (Drain) diffusion layer 120 are in the semiconductor substrate, and the gate 119 is located in the thin film dielectric layer 12, so that the channel can be formed on the semiconductor substrate 1 under the gate 119. The inside of the crucible is located between the source (s〇urce) and the drain diffusion layer 120. A plurality of layers of metal/dielectric layer 14 are disposed on the thin film dielectric layer 12, wherein the patterned metal layer in the metal/dielectric layer 14 is formed, for example, by the aforementioned sputtering aluminum process or inlaid copper process. The dielectric layer in layer 14 is, for example, an oxonium compound formed by chemical vapor deposition.

The electrical pads 16 of the metal layer are exposed. The structure and use of the protective layer 18 herein can be referred to the structure and use of the protective layer 4 in Fig. 1a, and will not be described herein. After the formation of the protective layer 18, the previously formed semiconductor element such as M?s and the metal/dielectric layer 14 can be protected from damage by moisture, transition metal or foreign ion contaminants. Therefore, a relatively inexpensive process can be made to make thick and wide metal interconnects and a thick polymer layer formed on the protective layer 18, and can be fabricated in a clean room of a lower clean 13 1308785 clarity class, such as in Grade 1 or more clean room manufacturing, where Class 100 is defined as more than 100 particles exceeding α5 microns per cubic foot of environment. After the protective layer 18 is formed, a thick polymer layer 20 may be deposited on the protective layer 18. The material used to form the monolayer 20 is, for example, Hitachi-Dupont Polyurethane HD2732 or 2734 (p〇lyimide, PI), or Asahi Polyimine Ls_, 1-83005^ or 8124. Another material can also be used to form the polymer layer 2〇, which is BenzoCycloButene (BCB), the manufacturer is D〇w Chemical, for example, and the phenylcyclobutene is gradually substituted.

An epoxy group-containing material such as photosensitive epoxy resin su_8 (manufacturer Sotec Microsystems) can also be used as the material of the polymer layer. The deposition of the polymer layer 20 can be formed by spin coating (eg ) 〇 〇 ) ting) and hardening (egg), as described below: in spin coating a polymer such as a photosensitive polyimide. After the film (4) 18 and the electrical pad 16, the polymer film can be patterned by lithography to form an opening in the polymer film, and the electrical pad 16 is exposed, and then the polymer is polymerized. The film was placed in a vacuum environment or under a nitrogen atmosphere and used in a period of Celsius for a 4 hour hardening process. Alternatively, it may be other impurities. After spin coating, such as a non-inductive hetero-imine film on the tilting layer 18 and the electrical pad 16, the polymer may be placed in the vacuum ring. Brother or nitrogen atmosphere, and using the conditions of Celsius, for 4 hours of hardening process 'then can be patterned _ lithographic side of the polymer film' to form an opening in the polymer film, and exposed electricity Sex pad 16. To obtain a thicker polymer layer 2〇', the spin coating step can be repeated to form a further polymer-polymerized polymer layer formed in the previous layer to achieve the desired thickness, of which the second layer = 14 1308785 The film of the film is, for example, a photosensitive polyimide, which can then be micro-formed to form an opening in the polymer layer of the multilayer and expose the electrical pad 16 Then, the multilayer polymer film is placed in a vacuum environment or a nitrogen atmosphere, and subjected to a 4 hour hardening process using a condition of 380 degrees Celsius, so that a thick polymer layer having a multilayer polymer film can be formed.

Alternatively, if a thicker polymer layer 2 is to be obtained, the step of spin coating may be used to repeatedly form another polymer film on the previously formed polymer film until the laminated polymer film is laminated. Achieving a desired thickness, wherein the laminated polymer film is, for example, a non-photosensitive polyimine, and the multilayer polymer film is placed in a vacuum or nitrogen atmosphere and is used at 38 Torr. The condition of 'degree of 4' hardening process, then the side of the lithography side can be used to pattern the multilayer polymer fine 'by forming a shape in the multilayer polymer film' and exposing the electrical pad 16 Thus, a thick polymer layer 20 having a multilayer polymer film is formed on the protective layer 18.

When the polymer layer 2 is printed, an area can be left unprinted to form an opening, thereby exposing the electricity. The pad 16 can eliminate the lithography or micro-steps, wherein the polymer layer material is, for example, poly-imine, then (10) the polymer layer 2G is placed in a vacuum or nitrogen atmosphere. And use a condition of Celsius to perform a 4 hour hardening process. Alternatively, the polymer layer 2 can also be formed by heat-pressing a dry film having an opening in the protective layer. Thus, the polymer layer having an opening pattern can be directly formed on the protective layer is. The opening in the polymer layer 20 exposes the electrical pads 16, so that the steps of silk or micro-secret can be saved. Alternatively, the polymer layer % can also be used to make the film on the protective layer 18, and then use the side process to form the dry mouth after the hot pressing, which exposes the mat. 16, it can save the steps of silk shadow or micro-carried.
