Field of the Invention The present invention relates to applying a force to a periphery of a film-like reticle to cause the reticle to be elastic, so that a pattern and/or shape including a plurality of positional alignment marks on the reticle is drawn. The reticle used in the exposure method in which the pattern is transferred onto the substrate is described later at the alignment position of the reticle and the substrate. ❾ [Prior Art] The above-described exposure method is disclosed in Japanese Patent No. 340268. Next, the principle will be described based on Fig. 5 and Fig. 6. As shown in the figure, a plurality of 102s for applying a pulling force to the peripheral edge portion of the mask 101 are provided as a force applying means. The actuator 102 is attached to the base member 103 by surrounding the reticle. The movable end 104 of the actuator 102 is shaped as a hook 105. On the other hand, a plurality of holes (©) 106 are formed in the peripheral portion of the mask 101. The aperture 106 can receive and engage the hook 105 of the actuator 102 such that the coupling portion can pull the force imparting means, i.e., the actuator 102, to the reticle 101. The transparent glass plate 107 for maintaining the planarity of the mask 101 is supported by the member 103. The substrate 108 is disposed at a position facing the mask 101. The substrate is supported on the substrate supporting member 109, and the amount between the substrate and the mask 101 is variable. The side of the photomask 101 opposite to the substrate 108 is provided with a CCD image-capturing size. The reticle is actuated 101 into a long hole 105 force transmission base 108 gap camera 200947158 1 10. The CCD camera 110, whose position is changeable, can simultaneously read the position alignment mark 111 (Fig. 5) drawn on the reticle 101 and the position alignment mark 116 (Fig. 8) drawn on the substrate 108. Further, the pitch between the alignment marks 1 1 1 on the photomask 1 0 1 is formed to be somewhat smaller than the pitch between the alignment marks 1 16 on the substrate 1 0 8 . The mask area surrounded by the two-dotted line B in Fig. 5 is a pattern display area 112 in which the pattern drawing portion including the position alignment marks 11 in the area can be recognized. Further, the region of the reticle 101 surrounding the pattern display region 112 is a force transmission region 113 that can be recognized as a region for which the actuator 102 is connected to the force applying means, that is, the force transmitting region. When aligning the position of the reticle 101 and the substrate 108, first, the CCD camera 110 reads the state in which the alignment marks are overlapped, and moves the reticle 101 or the substrate 108 based on the data of the positional deviation amount so that each The positional deviation of the position alignment marks is averaged. Next, the actuator 102 is actuated to apply a pulling force to the reticle 101, thereby changing the pattern size and/or shape of the aligning mark 111, so that the position of the reticle 101 is aligned with the mark 1 1 1 and the substrate 1 0 8 The position alignment marks 1 1 6 are superposed on each other with high precision. After the alignment of the photomask 101 and the substrate 108 is completed as described above, the light 114 for exposure (FIG. 6) is irradiated to the substrate 108 through the mask 101, and is drawn in the pattern display region 112 of the mask 101. The pattern is transferred onto the substrate 108. Thereby, the pattern is transferred onto the substrate 108 in a state in which the dimensional accuracy is high and the alignment accuracy is high. [Patent Document 1] Japanese Patent No. 340268 No. -6-200947158 [Disclosed from the Invention] [Problems to be Solved by the Invention] The above-described exposure method uses a conventional photomask which is still larger than the photomask used in the prior art. The reason for this is that the force transmission area 113 needs to be provided around the pattern display area 112 at the drawing. In the case of simply supporting the outer periphery of the mask during exposure, only the "supporting region" having a narrow width may be provided around the pattern display region 12. However, if the coupling force applying means is required, it is necessary to form not only the holes for connection, but also the width of the force transmission region 113 must be formed to be large in order to prevent the local distortion of the mask from directly affecting the pattern due to the tension of the actuators. As a result, it is necessary to form a photomask made of an expensive material to be large. As a result of comparing the size of the previous reticle 101 with the size of the previous reticle as shown in FIG. 7, the area of the previous reticle ιοί is about 2.6 with respect to the area of the pattern display area 112 surrounded by the two-dotted line B. The area of the previous mask shown by the two-dotted line C is about 1.6 times that of the pattern display area 112. This is because the area around the pattern display area 112 has to require a large force transmission area 1 1 3 in the case of the previous mask 101, but as long as the previous mask is as small as the support area 1 1 5 is fine. Fig. 8 is a plan view showing the substrate 108 disposed to face the reticle and the alignment mark 116 formed thereon. After the photomask and the substrate 108 are aligned, the pattern drawn on the photomask is transferred onto the substrate 108 by exposure. The reticle 101 has a size of about 2009 times the 200947158 compared to the substrate 108, but more than half of it is an unnecessary force transmitting region 113 made of an expensive reticle material. The problem caused by the large size of the mask is not limited to the increase in the cost of mask production. Since a large reticle cannot correspond to the current reticle drawing device, it is necessary to invest in new equipment in order to obtain a drawing device capable of corresponding to a large reticle. Thus, the object of the present invention is to separately form a central portion including a pattern display region and a portion containing a force transmission region, and then form a reticle by bonding, thereby achieving a reduction in material cost and avoiding new equipment investment. [Means for Solving the Problems] In order to solve the above problems, according to the present invention, it is possible to provide a force applied to a peripheral edge of a film mask to elastically deform the mask so that a plurality of position alignment marks are drawn on the mask. a mask used for an exposure method for transferring the pattern onto the substrate after the mask and the substrate are aligned, wherein the mask is configured to have: a central portion of the pattern; and the central portion is formed separately, and is entirely disposed so as to surround the outer peripheral edge portion of the central portion and is a force transmitting portion joined to the outer peripheral portion of the central portion, and has the center The portion of the elastically deformable force imparting means connects the force transmitting portion of the connecting portion. The force transmitting portion may also be formed by a plurality of strip members which are individually formed for each side of the central portion, and the strip members are respectively joined to the sides of the central portion of -8 - 200947158 to form a mask. . Alternatively, the force transmitting portion may be formed as a single frame-like member, and the frame member may be joined to the central portion to form a photomask. Alternatively, the force transmitting portion may be formed by a pair of L-shaped members formed for the two sides adjacent to each other at the center portion, and the pair of L-shaped members are joined to the central portion to form light. cover. The central portion and the force transmitting portion are bonded to each other on at least one side of the pair of faces by a state in which the end faces of the opposite faces are opposite to each other. The connecting portion may constitute a plurality of holes for hooking the hook formed at the movable end portion of the actuator, which is a force applying means. The above-described force transmitting portion may be composed of a material having the same Young's modulus as the material for forming the central portion. [Effect of the Invention] According to the reticle of the present invention, the central portion of the pattern is drawn, and the force transmitting portion that transmits the force to the central portion to elastically deform the central portion is formed separately. The communication part does not need to be made of expensive mask material, and can be constructed with cheaper materials. Therefore, the use of a portion of the expensive material is reduced, and the manufacturing cost of the entire reticle can be reduced. Further, in the case where the mask is drawn, the drawing device may be disposed in a central portion in which the force transmitting portion is in a separated state. The central part is to describe the size of the device for the status quo, so there is no need to invest in the new _. -9- 200947158 In addition, when the force transmission part is made of the material having the same Young's modulus as the central part constituting material, the force transmission part can be stretched as the center part, even if it is 2 different The joint structure of the members does not distort the whole. [Embodiment] BEST MODE FOR CARRYING OUT THE INVENTION Fig. 1 is a plan view showing a reticle 1 according to an embodiment of the present invention. The reticle 1 is provided with a central portion 3 in which a pattern including a plurality of positional alignment marks 2 has been drawn, and a force transmitting portion 4 which is entirely disposed to surround a peripheral edge portion of the central portion 3. The force transmission part 4 is made separately from the central part 3. The central portion 3 can be divided into a region surrounded by a two-dotted line d, that is, a pattern display region 5 in which a pattern is drawn in the region, and a mounting region 6 surrounding the region. The central portion 3 is made of the same or equivalent material as the material for forming the mask. In this embodiment, the force transmitting portion 4 is constituted by four strip-shaped members 4a to 4d which are individually formed on the respective sides of the center portion 3 as shown in Fig. 2 . Each of the strip members 4a to 4d is joined to each side of the center portion 3, respectively. At the time of joining, the peripheral edge end surface of the mounting portion 6 of the center portion 3 and the edge end faces of the respective strip-shaped members 4a to 4d facing each other are opposed to each other, and the tape 7 is attached along both edge faces (see the first Figure). The tape 7 can be attached to only one side of the edge end face to the face, or it can be attached to both sides. The edge faces of both sides may be in contact with each other' or may be close to each other. Further, it may be replaced by a tape-10-200947158 7, or a tape 7 may be used while being applied to the peripheral edge end surface of the mounting region 6 of the center portion 3 and the respective strip members 4a to 4d opposed thereto. Between the edges of the edge. Other suitable mechanical joining means may be used. In order to improve the joint dimensional accuracy, it is preferable to use the fixing tool strip members 4a to 4d, and a plurality of holes (long holes) 8 are provided as the force imparting means. A hook (not shown) of the movable end of the actuator is used for hooking. These holes 8 are connecting portions for constituting a force applying means for deforming the in-plane elastic deformation of the center portion 3. In the form of the other connecting portions, for example, irregularities (not shown) may be formed in the respective band members 4a to 4d, and the movable end portions of the force applying means may be engaged with each other to form a force. The force transmission part 4 does not depict a pattern. Therefore, the force transmitting portion 4 does not have to be made of the same expensive material as the central portion 3, and a more convenient material can be used. Specifically, the central portion 3 is made of a material that is passed through a photomask material, that is, PET (polyethylene terephthalate) coated with a photosensitive material, and the force transmitting portion 4 is uncoated with a photosensitive material. Made of PET in the state of application. Since the Young's modulus of the two is substantially the same, the same secondary development is applied when the tension is applied. Therefore, even in the joint structure of the different members, the twisting does not occur at the time of stretching. In addition, the PET material used in the part 4 can be used not only without applying the photosensitive material, but also without requiring the PET material used in the central portion 3 to be "perfect", so that a cheaper material can be used. Fig. 3 is a plan view showing a mask of another embodiment of the present invention. The reticle 11' is provided with a central portion 3 of -11 - 200947158 in which a pattern including a plurality of position alignment marks 2 has been drawn, and a force transmitting portion 14 which is entirely disposed to surround the peripheral edge portion of the central portion 3. The force transmitting portion 14 is formed separately from the central portion 3. In this embodiment, the force transmitting portion 14 is formed as a single frame-like member as shown in Fig. 4.
