Description of the invention () The invention of the leading city: The present invention relates to a pre-wet processing system and method for wafers during metal plating in semiconductor manufacturing processes, and in particular, to uniformly coating fluid on wafer surfaces by spray spraying devices during metal plating, To facilitate the formation of metal bumps. Inventing the global industrial development trend, electronics, information and communication have become the industries with the largest output value and rapid growth. Both the active and passive component industries and the electronic materials industry have their main goals of portability, high functionality and high density. , And to meet the thin and short electronic products related technology, to carry out technical upgrades and integration ', especially the major changes in the chip packaging industry. In the current packaging technology, flip chip technology provides the largest number of output / input (I / O) and packaging density, and the most basic step in flip chip technology is the manufacturing of chip bumps (Bllmp) The wafer bump is usually a combination of a multi-layer buried metal (UnBM metal) layer, and its functions include the adsorption of a hot electrode, a diffusion barrier layer, and wettability, and the reaction between layers must be avoided. A metal material is plated on the buried metal layer (UMB) as a conductive metal bump. Specific "In the process of electroplating metal, the wafer must be pre-wetted to facilitate the formation of complete metal bumps, and to avoid the formation of air bubbles or voids in the openings on the surface of the wafer, thereby hindering the electrical conduction function . Figures 1-2 show a conventional pre-wet processing system and method for wafer 1000. First, in step 202 ', the wafer 100 is taken out of the cassette and placed in the wafer holder 102. In step 204, the wafer holder 102 is placed in the water tank 104.

In the description of the invention (), and manually immersed the wafer holder 102 in the water tank 〇 04, so that the plating solution 106 is distributed on the surface of the wafer 100. . In step 206, a metal plating process is performed on the wafer 100 to form plated metal bumps (not labeled) in the openings (not labeled) on the wafer surface. In step 208, the wafer 100 is rinsed to remove the plating solution 106 remaining on the surface of the wafer 100. However, the conventional wafer 100 is manually pre-wetted, and the surface tension of the plating solution has a tendency to shrink the package size. It will inevitably make the wafer 100's pre-wetting effect poor, resulting in many metal bumps containing 2 Holes, bubbles, and even subsequent high-temperature reflow soldering processes destroy the conductivity of the metal bumps and cause the phenomenon of conductive circuit breakage. In addition, the conventional pre-wet processing method is not sufficiently automated, that is, the manual pre-wet processing is only used for wafer pre-wet processing, so it cannot meet the current demand for large-scale product manufacturing. The general purpose of the Mingmingfa 0 Uniform surface of the surface of the crystal is opposite to the installation of spraying the purpose of the main purpose of the hair convex convex shape accumulation of the conductivity of the body flow by the time of gold plating to facilitate the body flow .

The fluid jetting direction of each nozzle 316 is perpendicular to the surface of the wafer 3 2 4. By controlling the jetting pressure and flow rate of the jetting fluid, the fluid is forcibly injected into the wafer 324. An opening 400 on the surface, where the opening may be a winter hole defined by a light group film on the wafer 324, and the opening 400 is used to form a wafer bump, and the wafer bump may be a multilayer metal buried layer (UBM) composite material. Each control switch 310 is connected to a pressure converter. The control switch 310 may be, for example, an air valve for activating / deactivating the injection module 3 1 4. Each flow regulating valve 3 1 2 is connected to a control switch 3 1 0 to control the fluid flow of each injection module 3 1 4 and displays the fluid flow to facilitate control operation. Due to the proper spray pressure and flow rate, the fluid can be atomized to a higher degree, that is, the surface tension of the fluid is overcome, and the fluid is smoothly injected and stays within each of the openings 400 to facilitate subsequent metal plating, The use of the fluid's electrical conduction effect allows the metal bumps to be deposited and deposited in each of the openings to avoid the formation of air bubbles or voids, so as to form dense and better metal bumps. The electroplated metal such as It may be copper (Cu) metal, and the fluid may be, for example, a plating solution or pure water. If pure water is used as the fluid, since pure water is forcibly filled into the openings 400, in addition to producing a better cleaning effect, air bubbles or voids can be avoided within the openings 400.

Description of the invention () The consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs prints the vertical movement so that the injection module 314 completely covers the area of the entire wafer 324. Among them, the height adjustment device 322 can be an automated robot arm, for example, when the height adjustment device 322 After the wafer carrier 3, 8 is driven to move up and down 3 to 5 times, the openings 400 on the surface of the wafer 324 can obtain the best wetting effect. Continuing to refer to FIG. 5, it shows a method for pre-wetting the wafer during the electroplating process of the present invention. In step 502, the pump 304 is used to draw and output fluid from the fluid supply device 302, and adjust the total pressure of the fluid. In step 504, the total flow of the fluid is adjusted using the flow regulating device 306. In step 506, the position of the wafer 324 is moved, and the height adjustment devices 322 are used to adjust the heights of the plurality of wafer carriers 3 丨 8 located above the fluid tank 320, so that the Japanese-Japanese film-bearing technique J 1 8 is vertical to the wafer. The normal direction of the 3 2 4 surface is reciprocated over the fluid tank 3 2 0 back and forth. In addition, the steps of adjusting the total fluid flow and moving the wafer position can be performed simultaneously or sequentially. Finally, in step 508, the fluid is sprayed on the wafer 324, and the fluid is forcibly injected into the wafer 3 2 4 by controlling the ejection pressure and flow rate of the ejected fluid, so that the fluid is injected and stays within the opening 4 0 0 in order to facilitate When metal is subsequently plated, a metal bump is formed in the opening 400 by utilizing the electrical conductivity of the fluid. In summary, the present invention discloses a wafer pre-wet processing system 300 and its method when electroplating metal, which has at least the following advantages: (1) the wafer 3 2 4 can obtain the best immersion effect before electroplating to improve electroplating The best quality of metal bumps or films. (2) Reduce the occurrence of 324 scraps of wafers in order to improve 9 paper sizes Applicable to China National Standard (CNS) A4 specifications (210 X 297 mm) Packing -------- Order -------- -Line (Please read the notes on the back before filling in this page) A7
