Description of the Invention () Field of the Invention: Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economics The present invention relates to a chemical agent supply (Dispenser System) system, and in particular to a method for cleaning wafers on the spot (In_Situ) and A chemical agent supply system for subsequent steps of removing strips (photoresist stripping; pfls). Background of the invention: Generally, in the wafer manufacturing process, when the photoresist is no longer needed after the etching process is completed, the photoresist must be removed to facilitate the next step of the lamp. There are two main methods for removing photoresist: wet and dry photoresist. The house photoremoval method uses organic or inorganic photoresist to dissolve the photoresist, and dry photoresist. The rule uses a plasma to reactively etch the photoresist to strip the photoresist. In order to completely remove the photoresist, the photoresist removal method is usually used in combination with the wet photoresist method and the dry photoresist method. In addition, between the dry photoresist removal step and the wet photoresist removal step, the wafer must be cleaned to remove impurities and photoresist residues. Semiconductor etching machines, such as TCP9600 Metal Etching from LAM Research in the United States, usually have three main systems: a main chamber, a decoupled source quartz (DSQ) reaction chamber, and an APM system. Among them, the metal etching is in the main reaction 2 The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 meals) {Please read the precautions on the back before filling this page) Installation-line-· · 502301 B7 5. Description of the invention () The dry etching method is used in the chamber. The DSQ reaction chamber also uses the dry photoresist method to remove the photoresist of the wafer. The APM system first adsorbs the wafer on a rotating device and then injects it into, for example, De-ionized water (DI · Water) and nitrogen (n2) to clean the wafer 'both have the functions of cooling and preventing wafer corrosion. As shown in FIG. 1, FIG. 1 is a schematic diagram showing a structure of an ApM system of a conventional metal etching machine. The conventional metal etching machine includes at least a machine platform 100, wherein the machine platform 100 has a removal hole 60 for excluding liquids, such as deionized water; the rotating device 30 is installed on the machine platform 100, where The rotation device 30 further includes at least a rotation motor 30m, a wafer adsorption device (Chuck) 30c, and a transmission shaft 30s. The transmission shaft 30s is connected to the rotation motor 30m and the wafer absorption device 30c to rotate the wafer adsorption. The device 3 0c ′ and the wafer 80 is adsorbed on the wafer adsorption device 3c by the Bernoulli effect generated by the rotation; the gas spraying device 20 is installed on the machine base 100 to spray the gas For example, nitrogen gas is on the wafer 80; and the liquid spraying device 10 is installed on the machine base 100 to spray liquid, such as deionized water, on the wafer 80, and the liquid spraying device 10 has a Corresponding liquid draining device 110 includes at least a collecting element 110b and a connecting pipe 1 1 0 d, wherein the collecting element 1 1 0 b may be, for example, a funnel type, and the connecting pipe 1 10d is a liquid From the exclusion hole 60 of the machine base 100 Set metadata Ministry of Economic Affairs Intellectual Property Office employees consumer cooperatives printing equipment --- * (Please read the notes on the back of this page and then fill in) pieces 1 l〇b excluded. The APM system of the conventional metal etching machine is as follows: "% start the rotary motor 30m, and then inject deionized water and nitrogen to clean the wafer 800. It also has the function of cooling and preventing wafer 80 corrosion. 502301 A7 B7 V. Description of the invention (After completing the wafer cleaning step of the APM system of the metal etching machine, the PRS step is performed by the wet photoresist method to completely remove the photoresist on the wafer. This PRS step is usually Residual photoresist is removed using, for example, ACT690 solution and NMP (l-methyl-2-pyrrolidone) manufactured by Ashland Chemical Company, USA, where _ACT690 is used to remove residual photoresist, and NMP is used to neutralize ACT690. Do this After the Prs step, it is also necessary to use, for example, deionized water and nitrogen to clean the wafer. Recently, more and more semiconductor etching machines use Wafer Auto Cleaning (WAC) mode to perform etching to extend the preventiveness. Preventive maintenance (PM) cycle. So-called a wafer is cleaned in the main reaction chamber immediately after the main reaction chamber is etched to "make the main reaction pay to keep clean" and thus reduce Less particulate pollution and delay of PM time, which will improve wafer quality and reduce the time and money required for pM. However, when the etching machine adopts the WAC mode, the wafer must wait for the main reaction chamber to be cleaned before it can be cleaned. The rate of entering the main reaction chamber for the engraving process will be slowed down by increasing the waiting time. Therefore, when the money engraving machine uses the WAC mode, the rate of wafer processing per hour (Per Hour; WPH) will be higher than that without WAC. The mode is low. How to make up for the loss of WPH mentioned above has become a major issue.

Description of the invention () The chemical agent supply system includes at least one control device (not shown) to control the exclusion options The position of the collection plate 90 of the device, the circulation pump 21〇p The switch of the circulation pump 3 10P, the switch of the rotation motor 30m of the rotary device 30, and the control of the flow of gas, liquid and chemical agents, etc. Therefore, the steps of cleaning the wafer and removing the photoresist can be automatically completed. Motor 30m to the maximum speed, such as about 3000rpm. Then rotate the collection element 90 to ACT690, such as the collection element 21 Ob aligned with the exclusion hole 60, and then start the circulation pump ACT 6 9 0, such as the circulation pump 2 1 0p ACT690 is sprayed at a flow rate of, for example, about 4 per minute per liter (1 / m) to about 5 1 / m. After spraying, the circulation pump A C 690 is turned off, such as the circulation pump 2 1 0 p. The aforementioned rotation of the collecting plate 90 and the circulation pump 3 1 Op of the NMP are repeated so that the NMP is sprayed at a flow rate of, for example, about 4 1 / m to about 5 1 / m. To spray deionized water, simply rotate the collection plate 90 to the deionized water collection element, for example, the collection element 1 10b, align the exclusion hole 60, and then spray the deionized water. As for spraying nitrogen, it can be sprayed directly because it does not need to be recovered or discharged. The above description is only a description of a preferred embodiment of the present invention. The present invention can be adjusted according to actual needs, instead of being applied to the aforementioned APM system of a metal etching machine. According to the present invention, a plurality of chemical agent circulation devices, gas spray devices, liquid spray devices, and liquid discharge devices corresponding to these liquid spray devices can be installed according to actual needs, and the total number of chemical agent circulation devices of the liquid discharge device can be installed according to the actual needs.
