Description of the Invention: [Technical Field of the Invention] The present invention relates to a device for confining memory disks, wafers, and the like for transporting, storing, or processing. More specifically, the present invention relates to a composite wafer fixing structure. [Prior Art] Some containers are used to transport and store batches of wafers or disks before, during or after processing a disk or wafer. The wafer is processed into an integrated circuit, and the magnetic disk is processed into a magnetic storage disk for the computer. As used herein, "wafer" refers to germanium wafers, magnetic substrates, and the like. Processing a wafer into an integrated circuit wafer often involves several steps in which the disk is to be processed, stored, and transported over and over again. Due to the precision of the disk and its great value, it is important to properly protect and secure it throughout the program. Accordingly, the wafer container is generally configured to receive a wafer carrier that wraps the wafer in the slot or shelf member at the periphery of the wafer. Some conventional containers are constructed to accommodate a string of carriers, such as a standardized mechanical interface (SMIF) cartridge. The SMIF box typically has a bottom open door panel for pick and place wafered H-type carriers and typically includes a wafer holder to prevent a given wafer from being aligned with respect to its alignment plane. Slide horizontally. The wafer holders can include a channel-like structure operatively coupled to the actuators in the dome of the SMIF box. The actuation mechanism rotates or translates the wafer holder to contact the wafer edge when the bottom or door is engaged. The wafer container is easy to directly and movably contact the outer periphery of the wafer contained in the SMIF box. The angle defined by the intersection of the outer perimeter of the wafer and the major surface is often sharp. These 200816346 acute angles can cause local chipping or dents on the wafer holder when contacting the wafer holder, which in turn can contaminate the wafer in the container. Conversely, the acute angles themselves may also be prone to such cracks or depressions. This may also contaminate the wafer. Even in the case where there are no dents or chipping in the wafer or wafer holder, the wafer holder will generally slide axially or tangentially along the edge of the wafer while the wafer is being bonded, which can produce fine particles. And contaminating the wafer. SUMMARY OF THE INVENTION Materials that are well suited for making one part of a container may not be well suited for different parts of the same container. For example, polyetheretherketone (PEEK) is a material with ideal wear resistance, which is very suitable for wafer contacts, but it is difficult to mold and may be relatively relatively good compared to other plastics that can be used. expensive. Therefore, PEEK may not be a good material for the main body or structural components of the wafer container as other plastics such as polycarbonate. Correspondingly, the composite wafer holder of each embodiment of the present invention comprises a support portion having a first material and an operable or reshaped molded portion having a different material to form the portions firmly bonded together The gapless airtight interface. Embodiments of the invention include wafer holders having such re-molded portions and a method of making such wafer holders. In one embodiment, a remolded wafer holder for securing a plurality of wafers in a wafer container comprises: a base comprising a first material and comprising at least one edge having an edge a plurality of wafers for engaging the plurality of wafers in the wafer container; a repeating molding portion including a second material disposed at least partially along an edge of the at least one obstruction portion, the second The material is thermo-physically bonded to the 200816346 first material such that the re-molded portion can be fastened to the base without the use of separate mechanical fasteners. The second material can be disposed on the first material to prevent the first material from chipping, denting, or abrading. In another embodiment, a container portion having a door frame cooperates with a door to form a housing. The housing houses at least one wafer. An actuating mechanism is operatively coupled within the housing proximate the inner wall of the container portion. When the door is placed in the door frame, one end portion of the actuating mechanism can extend away from the inner wall. A wafer holder is operatively coupled to the actuation mechanism. The wafer holder may include a base having a base material of a first material and having a remolded portion of a second material, the second material being thermo-physically bonded to the first material to enable the The re-molded portion can be fastened to the base without the use of separate mechanical fasteners. The re-molding portion contacts each of the edges of the at least one wafer when the end portion of the actuating mechanism extends away from the inner wall. The second material can be tailored to impart specific mechanical and/or electrical properties, such as softness, wear resistance, and higher electrical dissipation qualities. An advantage of a particular embodiment of the invention is that a minimum of material and labor costs can be <<>> made into a securing mechanism with enhanced performance characteristics. Another advantage of certain embodiments of the present invention is that the size of the final component can be fine tuned to fit the dimensional tolerance. Yet another advantage of certain embodiments of the present invention is that a substantially integral wafer holder is formed by molding or fusing the two portions together. The joint between the two different materials can be gap-free, airtight and strong, thereby reducing the likelihood of trapping contaminants or other chemicals between the materials. Yet another advantage and feature of a particular embodiment of the present invention is that the selection of the re-molding material 7 200816346 is capable of reducing friction, wear and particle generation during use. [Embodiment] Referring to Figures 1A, IB, 1C and 2, there is shown a wafer container 10 according to an embodiment of the present invention. The wafer container 10 comprises a dome or container portion 12 and a door 14. The particular embodiment shown is a SMIF box in which the container portion 12 is generally cylindrical in shape and has a front wall 20, a rear wall 16, two side walls 18 and 22, a top portion 24, and a bottom assembly 26. The bottom assembly 26 includes a door 14 that can seat within a door frame 28 to form a housing 27. A plurality of wafers 29 having edges 29.1 can be received in the housing 27 and can be held by a string carrier (not shown). In the illustrated embodiment, the actuating mechanism 30 rests against the top portion 24 proximate the inner surface 3 of the rear wall 16 . In other configurations, the actuating mechanism 30 is operatively coupled to the wall 16 , 18 , 20 or 22 . One, or coupled to the door 14. The actuating mechanism 30 includes a frame 32 for supporting an upper mandrel 34 and a lower mandrel 36. A pair of tie rods 38 and 40 each extend from the mandrels 34 and 36, respectively. The tie rods 38 and 40 each define a distal end portion 42 and 44 of the actuator 30, each of which supports a cylindrical pivot 46, 48, respectively. A re-molded wafer holder 50 has a front side 51 and a back side 52 that are operatively coupled to the cylindrical pivots 46 and 48. Referring to Figures 3 through 8, an embodiment of a remolded wafer holder 50 is illustrated. The remolded wafer holder 50 can include a base portion 54 and a repeat molding portion 56. The base 54 can be formed by an injection molding process and can be made of a relatively hard polymer such as polycarbonate. The re-molded portion 56 can be made of a different material having one of the desired physical properties (e.g., comparable softness, abrasion resistance, and/or some electrical dissipation characteristics). An exemplary and non-limiting material of the re-molded portion may be a thermoplastic such as Polyether 8 200816346 (PEEK) or a material having a certain conductive property such as carbon doped or carbon filled ρΕΕκ.

The central bridging member 74 can extend between the yokes 62 and 63, and the swell can include an arched portion 76 shaped to accommodate the cylindrical shape when the wafer holder 50 is operatively coupled to the actuating mechanism Pivot 46. Similarly, the lower jaw clamp assembly 78 can extend from the beams 64 and 65. The lower portion 78 can be substantially similar to the upper clip assembly 68, such as having two L-shaped components and 82 and a central bridging member 84 with an arch 86 shaped to accommodate the cylindrical pivot Shaft 48 ° In the embodiment shown in Fig. 3, a bridge plate 87 extends between the beams 65 and 66. A post 88 can be raised away from the back side 51 of the remolded wafer holder 50. The post 88 is shown extending from the beam 65 in the figures, but it may also extend from any portion of the base 54. More than one strut member 88 can be utilized. A wheel 9 having a free end 92 extends from the beam 66 along a central axis 67 and a wheel 94 operatively dissipates the wheel 90. In this configuration, the wheel 94 projects beyond the free end 92 of the yoke 90. The L-shaped furcation members 70, 72 and 80, 82 cooperate with the respective central bridge members 74 and 84 to securely clamp the re-molded wafer holder 50 to the cylindrical pivots 46 and 48 (1, IB, 1C) And 2 pictures). In the particular embodiment illustrated in Figure 3, the obstruction portions 58 and 59 each include a proximal end portion 96 and a distal end portion 98. The proximal end % of the obstruction portions 58 and 59 can be coupled to or integral with the crossbar 9 200816346 61-66 and can be substantially orthogonal to the beam 61_66. In one embodiment, each distal end portion 98 extends from each proximal end portion 96, respectively projecting away from the central axis 67 at an oblique angle 100 relative to the proximal end portion 96, and defining an edge 102 substantially opposite the central axis 67. A ridge 1b4 made of a re-molding material 105 may be disposed on the edge 102. The repeat molding portion 56 can be disposed on the base 56 using a thermoplastic injection molding process. An example of such a process is disclosed in U.S. Patent Application Serial No. 11/092,528, filed on March 29, 2005, which is incorporated herein by reference. U.S. Patent Application Serial No. 6,871,741, which is incorporated herein by reference. Part of the continuation of the application is disclosed in U.S. Patent No. 6,428,729 issued on Aug. 6, 2002. Each of the references to the present invention is hereby incorporated by reference in its entirety in its entirety in its entirety in its entirety in its entirety in its entirety herein in its entirety The patents disclose composite wafer carriers and containers wherein the wafer support structure is formed by re-molding a first thermoplastic material onto a second thermoplastic material different from the first thermoplastic material. The re-molded component forms a gap-free, airtight interface that securely bonds the portions together. In particular, U.S. Patent No. 6,871,741 discloses the re-molding of transparent windows, latching mechanisms, and wafer contacts for supporting wafers. In use, the re-molded wafer holder 50 engages the edge of the wafer 29 contained in the wafer container 1 200816346 to secure the wafer 29 to a wafer carrier such as an H carrier (not shown). Inside. With the door 14 removed, the re-molded wafer holder 5 is suspended above the opening of the frame 28 in a retracted position (Fig. 1A) with the wheel 94 at the lower limit point. The post 88 abuts against the inner surface (not shown) of the rear wall 16 thereby preventing the rotating member of the actuating mechanism 30 from overstretching in the retracted position. When the door 14 is placed within the frame 28, the door 14 contacts the wheel 94, thereby moving the re-molded wafer holder 50 upward toward the top 24. The upward movement of the re-molded wafer holder 5〇 causes the pull rods 38 and 40 to rotate about the mandrels 34 and 36, thereby further extending the re-molding round holder 50 away from the rear wall 16 and re-molding the wafer. The raised ridges 104 of the holder 5 are bridged to the periphery of the contact wafer 29. Figure 1B is a schematic illustration of a remolded wafer holder 5Q in an extended or contact position. The wheel % enables the re-molding of the wafer holder 50 to be able to level along the inner surface of the door 14 without excessively generating particles. The bridge plate 87 effectively strengthens the beam 66 to resist the moment or torsional load transmitted by the reaction force transmitted to the wheel 90 when the wheel 94 is tempered. The basin should also be 'introspected' to utilize the actuation mechanism 30 and the repeated molding of the wafer holder 50 (for example, the actuation mechanism 30 does not include the wheel 94), and this still falls within the scope of the present invention. . See Fig. 9 " to Fig. 11' The repetitive molding and airlift of the remolded wafer holder 50 will now be described in more detail. One method involves casting the base 54 in a first mold and then applying a base to the repeat molding portion 56. The second mold is equipped with a pulse path system 106 to enable the re-molding material 105 to approach the edge 1〇2 of the rail portions 58 and 59. The first method involves a first mold that includes the conditions for providing the vascular system 106, which is adapted to the insert (not shown) as desired. The inserts are placed in the channels defining the venous system 106 during injection molding of the base 54. After forming the base 54, the base 54 is removed from the mold and the insert is removed from the passageway. The base 54 is then repositioned into the first mold and the repetitive molding material 105 is injected through the now vacant passage to form the venous system 106 which delivers the re-molding material 105 to the edges 102 of the track portions 58 and 59. In both methods, the mold can be formed by an upper mold portion that cooperates with a lower mold portion that has a boundary line 108 positioned to enclose the base portion 54 and the pulse system f ' 106. It should be noted that although the mold portions are not shown in the drawings, the upper mold portion is located in the area marked by the letter "A" above the boundary line 108, and the lower mold portion is located below the boundary line by the letter "B". In the marked area. The boundary line 108 is capable of fully defining a so-called "steel safety interface" 110 between the wafers 29. The steel safety interface includes the portion of the remolded wafer holder 50 that is in contact with the edge of the wafer 29. The steel safety interface preferably has no sharp corners and typically has a rounded surface 112 in contact with the wafer 29. The steel safety interface 110 has a protruding dimension 114 that projects beyond the base in the direction of the wafer 29. The position of the dividing line 108 enables the fine molding portion 56 to be finely adjusted to an optimum size, as needed. The molding process is prone to deviations that affect the size of the final component in an indeterminate but often repeatable manner. We can “fine-tune” the molding process by removing metal from the mold until the desired dimensional tolerance of the final molded product is reached. The component formed by the mold using the process is referred to as a "steel safety" component because the dimensional repeatability of the product made of the mold is generally excellent despite the deviation. 12 200816346 Therefore, in one embodiment of the present invention, we will reduce the size of the cavity on the upper mold portion for the size of the dog's out size 114 to be reduced in consideration of shrinkage factors and other known effects. The small steel formed a safety interface of 11 inches. Based on this result, it can be inferred that the amount of material to be removed from the mold portion for defining the protruding dimension 114 from the upper mold portion is estimated. Depending on the inferred value, it is optional to remove the amount of material that is slightly less than the calculated value to ensure that the resulting part is not oversized. After two or three trimming of the cavity, it is possible to form a mold that can be made into components within the dimensional tolerance. (See FIGS. 12A through 12C, which illustrate a front opening unified p〇d5 FOUP 120 having a door assembly 122 having a plurality of repeating modes in an embodiment of the present invention. Plastic wafer holder fingers 124. The re-molded wafer holder fingers 124 in this embodiment are operatively coupled to one of the inner surfaces 126 of the door assembly 122. The wafer holder fingers 124 The end portion 13A can be repeatedly molded from a material that facilitates contact with the wafer 128 contained in the FOUP 120. When the door assembly 122 is placed over the opening of the FOUP 120, the wafer holder finger 122 engages the F0UP. The wafer 128 is received to be securely biased against the wafer contact structure 132 ◎ within the FOUP 120. The re-molding material can be selected to protect the wafer holder fingers 120 and wafers 128. No chiseling, dents, and/or wear will occur.
