Definitions
- the invention relates to a device for treating substrates in a treatment fluid containing
- Fluid container with at least one receiving device for the substrates or for at least one substrate carrier.
- Devices of this type are known from the same applicant DE 44 13 077 AI and DE 195 46 990 AI and also in the unpublished German patent applications DE 195 37 879.2, DE 196 15 969.5, DE 196 16 402.8, DE 196 37 875.3 or DE 196 40 848.2 described by the same applicant.
- These devices have proven themselves very well for the treatment of substrates, in particular of semiconductor wafers, masks, CD's, CD-ROMs, other storage disks, such as hard disks etc., and of LED display panels.
- such devices have also been used for treating the substrates with rinsing liquid and for subsequently drying the substrates.
- the so-called Marangoni process was also used, according to which the substrates moved out of the treatment or rinsing fluid are acted upon by a gas, for example a mixture of isopropyl alcohol and nitrogen, which reduces the surface tension of the treatment fluid and this improves and accelerates the drying process.
- a gas for example a mixture of isopropyl alcohol and nitrogen
- JP 8-45883 A2 a substrate holder with two side walls is known, in which grooves for receiving the Substrates are formed. Drainage holes are provided in the grooves for receiving the substrates, via which fluid can flow out of the grooves. The substrates are not held in their lower area, so that fluid adheres to them, as in the previously described devices.
- JP 7-249604 A2 shows and describes a washing device for substrates which are located in a cassette.
- the washing liquid is drained down from the washing tank. Measures to remove residual liquid from the substrates or from the cassette are not provided.
- JP 1-312829 A2 a device for treating semiconductor substrates is known, in which an arm is provided which, after lifting the substrate cassette, wipes past on the underside thereof in order to remove any adhering drops.
- the arm itself is wet and distributes liquid over the entire underside of the cassette, so that a considerable amount of residual liquid remains adhering to the cassette.
- JP 4-317330 A2 JP 60-229339 A2 and JP 6-181196 A2 further devices for the wet treatment of substrates are known, which however also have the disadvantages that residual liquid adheres to the Substrates or on the cassettes stick after the treatment.
- the invention has for its object to provide a device of the type mentioned, with which the treatment and in particular the drying of the substrates with simple means is even more reliable and faster.
- the receiving device has a fluid suction device with suction openings, which are arranged to extract residual fluid after the substrates or substrate carriers have been lifted out of the fluid at the lowest contact points of the substrates or substrate carriers are.
- the fluid suction device is preferably put into operation when the treatment fluid, for example a rinsing liquid, has been removed from the substrates or from the substrate carrier, for example by actively lifting the substrates and / or the substrate carrier above the fluid surface or is, or that, especially in the case of the substrate carrier, the treatment fluid has been drained from the fluid container.
- the treatment fluid for example a rinsing liquid
- the suction openings are connected to a vacuum source. Via the suction openings, which are preferably holes, but can also be slits, the last fluid still adhering to the substrates, for example the liquid droplets still adhering to the lowest points of the substrates or substrate carriers, is suctioned off. According to a particularly advantageous embodiment of the invention, the suction openings are preferably provided at the deepest points of the substrates and / or the substrate carriers, since last fluid residues or droplets in particular collect and hold there.
- a further advantageous embodiment of the invention consists in that the receiving device is provided for at least one substrate carrier, and the suction openings are arranged at the locations of the receiving device at which the substrate carrier lies or rests on the receiving device.
- the substrate carriers rest or rest on raised support points of the receiving device, and there is a distance between the substrate carrier and the suction openings. This results in a better suction effect than if the substrate carrier lies on the suction openings over its entire support surface or edge.
- the substrate support rests on the receiving device at defined points, for example at two centering points arranged centrally in the longitudinal and / or transverse direction, so that at other points, for example over the other frame areas, the suction openings provided in the receiving device are at a distance from the substrate carrier.
- the receiving devices are designed or provided for receiving the substrates
- At least one droplet discharge element is provided which can be brought into contact with the lowest point of the substrates.
- a fluid suction device according to the invention also in connection with such a droplet discharge element is particularly advantageous.
- lifting devices are preferably provided in the devices for treating substrates in order to lift the substrates and / or at least one substrate carrier out of the treatment fluid.
- lifting devices are described which move the substrates and the substrate carriers at different speeds relative to one another using a differential stroke from the treatment fluid, preferably a flushing fluid.
- the suction openings or the channels are connected to the vacuum source outside the fluid container via an elastic hose.
- connections between the suction openings and / or the channel on the one hand and the vacuum source arranged outside the container are integrated in mounting elements of the receiving device, for example in the holding arms with which the receiving devices are connected to the lifting device . This results in a more compact design with reliable fluid extraction.
- FIG. 1 shows a schematic cross-sectional illustration of an embodiment of the invention, in which a substrate carrier is placed on a receiving device having a fluid suction device,
- FIG. 2 shows a schematic cross-sectional illustration of a device according to the invention with a droplet discharge element having a fluid suction device
- FIG. 3 shows an embodiment of a receiving device designed according to the invention for a substrate carrier in supervision
- Fig. 4 is a cross section of that shown in Fig. 3
- Fig. 5 shows a cross section of the receiving device shown in Fig. 3 along the section line V-V shown in Fig. 4.
- FIG. 1 shows a receiving device 1, shown only schematically, of a device according to the invention, which has support elements 2, 3 for a substrate carrier 4, in which substrates 5, in the exemplary embodiment shown disk-shaped semiconductor wafers, can be used.
- the support elements 2, 3 have suction openings 6, 7 at their tapering upper ends, which are connected via lines 8, 9, 10 to a vacuum source, not shown.
- the substrate carrier 4 is, for example, by using the maragon method already dry.
- treatment fluid still adheres, which in the embodiment shown in FIG. 1 collect on the underside of the feet 11, 12 as drops.
- the suction openings 6, 7 a negative pressure is applied, which aspirates these droplets remaining at these points. In this way, the substrate carrier 4 is easily and quickly dried even at its critical, deepest points.
- the substrates 5 are rectangular substrates, for example rectangular masks, which are to be treated or dried.
- the receiving device 1 has a first receptacle 22 with receiving areas 22 and 23 and a second receptacle 24 with receiving areas 25 and 26.
- a drop discharge element 27 in the form of a knife is connected to the second receptacle via arms 28, 29, so that the tip 30 of the knife-like drop discharge element 27 is at a constant distance from the second receptacle 24, and the bottom corner of the square one Substrate
- the droplet discharge element 27, like the support elements 2, 3 according to the embodiment shown in FIG. 1, has suction openings 31 which are connected to a vacuum source via a vacuum line 32.
- a receiving device 1 which is provided for receiving a substrate carrier 4.
- the receiving device 1 consists of a frame 33 which has support feet 34 to 37 on which the substrate carrier 4 lies.
- a plurality of suction openings 38 are provided in the frame, which are open at the top and are at a short distance from the undersides of the
- Feet 12, 13 of the substrate carrier 4 are.
- suction openings 38 are connected to suction channels 41 to 44, which extends essentially over the entire length and width of the frame elements and via which the air is suctioned off.
- the invention has been described above on the basis of preferred exemplary embodiments. However, numerous modifications, refinements and modifications are possible for the person skilled in the art. lent without leaving the inventive idea.
- the design of the suction openings 38 can be selected according to the requirements or circumstances.
- the channels 41 to 44 are preferably connected to an elastic hose which does not impair the movement of the receiving devices 1 and which leads to the vacuum source. According to an advantageous alternative embodiment of this exemplary embodiment, however, it is also possible to connect the channels via the holding elements or arms for the holding devices to the vacuum source outside the pool area, these holding elements and arms being connected to the lifting devices and the holding devices 1 move up and down.
