Description of the invention (1 [Background of the invention] The present invention is mainly related to the technical field of the seed layer for later metallization. More specifically, the present invention There is a method for repairing the seed layer before metallization. Small microelectronic devices such as sub-micron geometries have tended to contain multiple metallization layers for higher density processing. Generally used to form The metal wire on the semiconductor wafer is also commonly called wiring 'aluminum. The advantage of aluminum is that it is relatively cheap, has a low resistivity, and is very easy to be etched. Aluminum is also used as a via. ) Interconnects to connect different metal layers. However, although the size of the vias / contact holes has been reduced to the sub-micron range, it also caused the problem of step coverage. Instead, aluminum was used instead. When interconnecting different metal layers, stability issues arise. Such poor stage coverage causes high current density and also promotes electron migration There is a way to & an improved interconnect path for vias, which can use a metal such as tungsten to form a complete filled plug when using an inscription as a metal layer. However, tungsten The manufacturing process is not cost-effective and complicated. Tungsten has a high electrical resistivity, and tungsten plugs (tungstenplugs) can easily lead to poor interfaces between the void and the wiring layer. Copper can be used as a replacement material for interconnect metallization of integrated circuit manufacturing. Copper The advantages are better electrical properties than tungsten, better electron migration characteristics and lower resistivity than aluminum. Its disadvantages are that it is more difficult to do post processing than aluminum and crane, and it is easy to migrate to such as In order to avoid this kind of migration, it is necessary to use this paper before the copper layer deposition process.

Description of the invention (2 Barriers such as titanium nitride, nitride buttons, etc.) ) Layer. General metal layer application technology, various Electrochemical deposition is only suitable for applying copper metal to the conductive layer. Therefore, before the electrochemical deposition of copper, it is necessary to apply the bottom conductive seed layer of a metal seed layer such as copper to the substrate. There are many methods for applying the seed layer, such as physical vapor deposition (physical vapor deposition, PVD,,) and chemical vapor deposition (chemicai ^ 邛 邛 '^ 乂 ^' ^ Generally speaking, By contrast, the seed layer is relatively thin, such as a thickness of 5G to i Angstroms. The metal seed layer, especially the copper seed layer, may generate areas such as surface metal oxides (insulating plutonium) on the seed layer and the surface layer and discontinuities in the surface layer. This is due to insufficient deposition of the surface layer, such as metal deposits on visible lines. If a complete metal layer is to be electrochemically deposited on the seed layer, the discontinuity must be filled before or during the final metal layer deposition, or voids may occur in the final metal layer. PCT Patent Application No. WO99 / 4773! (Chen) discloses a method of providing a seed layer by a first vapor, wherein the first vapor deposits an ultra-thin seed layer, and then electrochemically strengthens the ultra-thin layer The seed layer is formed to form the final seed layer. According to this patent application, the two-stage process provides a seed layer that reduces discontinuities, that is, a seed layer that reduces areas where the seed layer covers incomplete or missing areas. 1 > Known bottom-over or over-filled electric ore copper Standard for paper towels Standard for household papers (CD-like cutting (2) 0 x 297 Public hair 2 lines 91944

Description of the invention (9) Generally speaking, the pH value of steel compound reduction is about i 5 to 4, and the best is about 2 to 2.5. The temperature of the reduction reaction is not very important. The reaction can occur at up to / m, but it is best to heat it slightly so that the reaction can occur at a temperature of about 80 to 90 ° F. If desired, the temperature can be higher (120 to 130 ° F), but the type and amount of reactants and the pH value are the main factors controlling the reaction. The reaction started gradually and it took 5 to 10 minutes for the reaction to appear. With copper sulfonate, you can observe the reaction result by changing the color, the color changes from dark blue to light blue, and finally to green. After completing the first part of the reaction as indicated by the color change, the heating or stirring should be stopped to maintain the state of the reaction mixture or the mixture should be allowed to react for a reaction time of 24 hours. After 24 hours, the gel is ready for use; however, it is best to leave it in an airtight container for another 3 to 4 weeks of curing. Generally speaking, the size of the steel colloid particles is about 10 to 100 nanometers (millimicron μm). In addition, after the initial reaction, if you want to enhance the stability of the colloid, you can add additional reducing agents, such as water and hydrazine, phenylhydrazine, hydroxylamme sulfate, or even DMB (or another initial Other reducing agents used in the reaction). After the colloid has been aged or stored for 24 hours, additional reducing agents can be added to the colloid, but it can be added at other stages after the initial reaction if necessary. After 24 hours of maturation, the pH value of the colloid is about 7, which can be used directly under this favorable acid test value, but the gum can be used in a very wide range of test values. If necessary, the acid-base value can be adjusted by adding acidic components (such as sulfuric acid) or test components (such as test hydroxide).

Description of the invention (10 is well known. During the use of Fb1, the acid value of the colloid may decrease, but in fact ► printed on the employee consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, the glue solution will be continuously replenished to make the pH value There is a tendency to return to 7, the colloid is best to keep slightly alkaline, such as the pH value is maintained at about 7 to 8 is better to maintain at about 7.8 to 8. Although copper is a better choice of colloids, but familiar with this art It is known that other suitable colloids such as nickel, iron, or cobalt can also be used in the present invention. The copper paste of the present invention is used to strengthen or repair the discontinuous part of the metal seed layer deposited on the substrate. Generally speaking, non- The continuous seed layer is in contact with the steel glue (1 to 2g / L copper is preferred) to produce a colloidal coverage or reinforced Seed layer. This colloid can be applied to the seed layer by various methods, such as dipping, spraying, bismuth spin coating, nod coding, etc. Spray and spiral coating. Basically, the colloid is used to fill or repair the discontinuous part of the seed layer in order to make the seed layer continuous. Therefore, the seed layer covered or reinforced by copper glue is basically Continuous. The advantage of the copper paste of the present invention is that the acid-base value is about 7, or the degree of light alkalinity. Therefore, the dissolution of the seed layer is reduced, such as the metal oxide of the seed layer is reduced. After the colloidal precipitation on the seed layer, the colloidal surface can be washed with water or an activated solution as required. The activated solution of the example includes a reducing agent solution, such as reducing any of the ionized palladium to Palladium metal (zero valence palladium). Any of the above are suitable reducing agents. The steel cement reinforced seed layer can be electroplated with various metals, but copper is usually used for electricity treatment. The electroplating operation can be based on electroless plating or electrolytic Plating The electroless plating can be used to further strengthen the seed layer. However, the paper size of the electroless plating is applicable to the Chinese National Standard (CNS) A4 (21〇χ 四 7).
