Soh et al., &Quot; Fabrication of lOOnm pMOSFETs with Hybrid AFM / ST M Lithography〃 (1 997 SYMPOSIUM ON VLSI TECHNOLOGY) Microfabrication technology of microscope. This is a general method of processing by applying a voltage between the probe and the substrate. It has high resolution and can be processed at the atomic level in principle. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. As disclosed in US Patent No. 5,666,190, it is a lithography system with a plurality of cantilevered imaging systems. [Summary of the invention] When a scanning probe microscope is used in a drawing device, in order to maintain a constant amount of irradiation from the probe to the substrate, it is necessary to control the application of the probe to the basic paper size-the national paper standard (CNS) A4 applies Specifications (210 X 297 mm) 4 472279 A7 B7 printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 5. Description of the invention (2) Voltage between boards. However, it is not suitable for high-speed processing due to the feedback processing of closed-loop control in this control. In addition, since the charge / discharge current for the floating capacitor between the probe and the substrate actually flows in a direction that hinders control, the processing speed becomes slower. In this way, it takes much more time to draw complex graphics by repeatedly repeating the ON / 0 F F state of the current. The present invention is mainly aimed at keeping the voltage of the irradiation current from the probe to the substrate almost constant even when a certain voltage is applied without performing feedback control when the drawing distance is short. That is, the feedback process is performed in advance, and then the voltage 値 that can obtain the desired irradiation current is measured and memorized, so that no feedback is applied during the actual drawing, and only 0 N / OFF of the memory voltage 进行 is performed. In this case, since the feedback processing may be performed only once for each predetermined drawing distance, the time can be greatly reduced compared with the conventional method in which feedback processing is often required. In addition, when this method is applied to a drawing device using a plurality of probes, since it is not necessary to control the current of each probe at the same time, a complicated control system is unnecessary, enabling higher-speed drawing. [Best Mode for Carrying Out the Invention] (Embodiment 1) Hereinafter, an example of a pattern drawing device for drawing a photoresist film using one probe in this embodiment will be described with reference to Figs. 1, 2 and 3.

The imaged portion 5 (coated with a photoresist layer 8 and a conductive layer) (Consisting of the substrate 6 of 7) facing the probe 2 and the drawn portion 5 is fixed to the Z driving portion 9 and the XY driving portion 10, and the in-plane direction and vertical of the drawn portion 5 can be scanned by the probe 2 direction. In addition, the XY driving section 10 is connected to the Z coarse movement section 1 1 ', so that the probe 2 can be roughly moved in the vertical direction with respect to the drawing section 5. The conductive layer 7 is connected to the current detection section 1 3, and the current flowing from the probe 2 through the photoresist layer 8 is detected, and the control section 12 adjusts the slave voltage application section 1 4 The voltage applied to the probe 2 enables a desired current to be generated. The voltage at this moment is temporarily stored in the voltage storage section 15 so that the voltage can be used later. In addition, the spring portion 3 is connected to the position detection portion 16, and the relative position in the vertical direction from the photoresist layer 8 of the probe 2 or the force applied to both is detected, and the control portion 1 2 The Z-direction displacement of the driving portion 9 is adjusted so that the probe 2 can be at a predetermined position. In addition, the control section 12 causes the X Y driving section 10 to be displaced, so that the probe 2 can move within the surface of the photoresist layer 8. Further, the input section 17 reads the predetermined pattern data into the control section 12 so that the position and current 探针 of the probe 2 can be controlled in accordance with the pattern data. Next, the operation when pattern drawing is performed using the apparatus of Fig. 1 will be described. First, in order to bring the probe 2 into contact with the photoresist layer 8, the coarse movement portion 11 of the probe 2 is used to approximate the two steps. After very close, a position feedback loop (consisting of the position detection section 16, the control section 12, and the Z driving section 9) is used to automatically control the vertical position of the probe 2. In addition, the size of this paper applies the Chinese National Standard (CNS) A4 (210 X 297 mm). The consumer cooperation of the Intellectual Property Bureau of the Ministry of Economic Affairs is made by Du Printing 472279 A7 B7. 5. Description of the invention (4) Read by the input department 17 Enter the pattern data, and the control unit 12 will control the position and current 探针 of the probe 2 according to the pattern data. Hereinafter, it will be described using FIG. 2. Figure 2 (a) is an example of a two-dimensional pattern data. Each element of the data indicates the 0 N / 0 F F state of the current, and the position of the data is the coordinates of the probes 40 a-4 0 d on the photoresist layer 8. Here, the ON bit 2 0 is represented by black, and the OFF bit 21 is represented by white. Fig. 2 (b) shows the operation of the probe 2 on the photoresist layer at the time of drawing. The control unit 12 draws a light scan based on the pattern data, but actually sets a voltage acquisition area different from the drawing area 2 3 (drawing a desired pattern) to obtain a drawing voltage in advance 2 2 . In this voltage acquisition area 22, a current feedback loop (consisting of a current detection unit 13, a control unit 12 and a voltage application unit 14) is formed at the beginning of each scanning line 24, and then the detection is performed. While scanning the needle 4 1 a, the voltage 値 is measured, and the voltage 値 is stored in the voltage storage unit 15. Once the probe 2 enters the drawing area 23, it will scan the current feedback to form a 0FF state. When the probe 2 is located at the drawing position corresponding to each 0 N bit 20 of the pattern data, it will be scheduled. The voltage 记忆 stored in the voltage storage unit 15 is applied at the same time, and when the probe 2 is located at the position corresponding to the 0FF bit 21, no voltage is applied or a voltage below the critical 値 of the current flow is applied. A pattern is drawn by performing the above operation in each scanning line 24. The pattern data does not have to be expressed in 1 bit of ON / OF F shown in Figure 2 (a), but it can also be expressed in multiple bits so that the corresponding currents are different for each number. In this case, in the field of voltage acquisition, this paper size will apply the Chinese National Standard (CNS) A4 specification (210 X 297 mm) -------------- Shang -------- Order --------- line (please read the notes on the back before filling out this page) 472279 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 V. Description of the invention () 2 The measurement in 2 corresponds to each The voltage 値 of the current 値 is stored in the voltage storage section 15. The measurement of the voltage 値 in the voltage acquisition area 22 is not necessarily performed in units of each scanning line 24, and may be performed on a plurality of scanning lines 24 at a time, or a plurality of times on each scanning line 24. The voltage obtaining area 2 2 can be located anywhere on the surface of the photoresist layer 8, but it is preferably located as close to the drawing area 2 3 as possible. In addition, since the voltage measurement in the voltage acquisition area 22 can also be performed in the used area, the area of the voltage acquisition area 22 can be reduced. In the pattern data shown in Fig. 2 (a), although the position of each data corresponds to the position of the probe 2, it is also possible to use the person who describes the coordinates of the probe 2 at the same time as the current data in the pattern data. Rendering is performed by vector scanning. To be more specific, the pattern data is an order in which a combination of an electric current 値 data and a start point and an end point coordinate data of the probe 2 is arranged to be drawn. The probe 2 moves from the start point to the end point while applying a voltage corresponding to the current 値 given by the pattern data, and repeats this operation to draw a desired pattern. In the voltage obtaining area 22, there may be a case where the correct voltage 値 cannot be obtained due to the influence of the state of the photoresist layer 8 or the state of the probe 2 and the like. This situation prevents the drawing on the scanning line 24 from being performed properly. To prevent this from happening, the voltage is measured on each of the scanning lines 24 in the voltage acquisition area 22 a plurality of times, and a plurality of voltages 値 are stored in the voltage storage unit 15. Then "select these voltages 重新 one after another without using a range exceeding a preset standard voltage’ "until a suitable voltage 能够 can be obtained. If all the voltages are inappropriate, then use the Chinese paper (CNS) A4 size (210 X 297 mm) memorized in the paper size of the book. --------- 1! _ 33 ^ --- 11 Order · ------- (Please read the precautions on the back before filling out this page) 472279 A7 ___B7 V. Description of the invention (6) Press the memory part 1 5 The voltage used in the previous scan line 1 4 value. As a result, highly reliable rendering can be performed. In the present embodiment, the displacement of the Z driving section 9 and the X Y driving section 10 is adjusted using a piezoelectric element and a voltage signal from the control section 12. Here, the mechanism of the Z coarse movement section 11 uses a stepping motor and a micrometer, but a method such as a lever type may also be used. Since the z-driving section 9 ', the X-y driving section 10, and the Z coarse-moving section 11 are relatively moving the drawing head 1 and the to-be-drawn section 5, they can be located on either side. The position detection by the position detection unit 16 is performed by using the laser light reflection generated by the spring unit 3. The substrate 6 is made of glass and has a chromium (C r) thickness of 20 nm to 1000 nm as a conductive layer, and a photoresist layer 8 having a thickness of about 10 nm to 100 nm (for example, A negative type photoresist of a mixed photoresist of poly (vinylphenol) and an azide group (RD2100N manufactured by Hitachi Chemical Industries, Ltd.).

Also, a suitable tip 2 has a radius of curvature of 10 nm to 100 nm, and the spring number of the spring portion 3 is 0. 0 5N / m ~ 5N / m, resonance frequency is 10kHz ~ 50kHz. In addition, the probe 2 will have conductivity by vapor-depositing titanium with a thickness of 10nm ~ 50nm. In addition to titanium, 'can also be used Manganese, molybdenum, titanium carbide, manganese carbide, molybdenum carbide, conductive diamond, etc. The following description will be made of the drawing method when the surface of the substrate 6 is not flat and there is a step difference using the third drawing. If there is a step on the surface of the substrate 6, not only the probe 2 cannot enter the area directly under the step to perform drawing, but also the probe 2 will collide with the step and be damaged. Here, 'to reduce the substrate The unevenness of 6 is applied, and a flattening layer 30 is coated on the surface of the substrate 6 to flatten the surface. Furthermore, the same conductive layer 7 and photoresist as shown in FIG. 1 are coated on the surface of this flattening layer 30. Layer 8. The drawing process is performed using the same pattern drawing device and method as in FIG. The development of the layer 8 causes a photoresist pattern to be formed on the conductive layer 7. Furthermore, the photoresist pattern is used as a photomask, and the conductive layer 7 and the planarization layer 30 are etched to be removed to remove the photoresist pattern. A pattern of the planarization layer 30 is formed on the substrate 6. For example, on a patterned silicon substrate 6, a photoresist (for example, manufactured by Hitachi Chemical Industry Co., Ltd.) is spin-coated so that a thickness of 300 nm can be formed. BL 0 C), a planarization layer 30 is formed, and a P-type silicon is vapor-deposited thereon to form a conductive layer 7, and a photoresist (for example, manufactured by Hitachi Chemical Industries, Ltd.) is coated with a film thickness of 40 nm.

Description of the invention (8) After drawing, make the pattern copied on the photoresist layer 8 develop Then use the photoresist pattern as a photomask, dry-etch the conductive layer 7 with carbon tetrafluoride gas, and dry-etch the planarization layer 30 with oxygen, thereby copying the pattern on the substrate 6 on. In the present embodiment, the results of actual drawing will be described using FIG. 4. Among them, a conductive silicon substrate was used as the substrate 6 to form a photoresist layer 8 with a photoresist RD2 1 0 ON having a thickness of 50 nm, and the conductive layer 7 was omitted. The probe 2 is moved on the photoresist layer 8 at a speed of 0.1 mm / s, and the current flowing between the probe 2 and the substrate 6 is set to 30 pA. The voltage applied at this moment is near -4 0 V. When a latent image is produced in the photoresist layer 6, in order to create a latent image, the probe 2 receives a Coulomb force acting between the probe 2 and the substrate 6 according to the applied voltage. By this Coulomb force, the spring portion 3 is deformed, and the probe is brought into contact with the photoresist layer 8. In addition, there are also parts that do not form a latent image in accordance with the desired pattern. Since no current is required at the portion where the latent image is not formed, no voltage is applied to the probe 2 at this position. However, if the voltage is set to 0 V, a Coulomb force that does not act on the probe 2 is formed, and therefore the spring portion 3 is not deformed, and the photoresist layer 8 is separated. In this way, when a voltage is applied again to the position where the latent image should be formed, the Coulomb force will suddenly act on the probe 2 and cause the spring portion 3 to deform rapidly. Therefore, the probe 2 will collide with the photoresist layer 8 violently, resulting in The possibility of damage to the probe 2 increases. Therefore, when drawing a portion where a latent image is not produced, it is desirable to control the voltage in such a manner that a small current can flow to the extent that a latent image is not formed. In this embodiment, if the applied voltage is set to -20 V or less, the current will form 1 pa or less.

Invention description () will not be formed. Here, the applied voltage 値 corresponding to 0 F F bit 2 1 of the pattern data is set to -2 0 V. The standard voltage range when determining the drawing voltage is set to 30V or more. Use the figure shown in Figure 4 (a) as pattern data, draw according to the above conditions, and observe with a scanning electron microscope for 1 minute soaking in 0.8% tetramethy ammonium hydroxide (tetramethy ammonium hydroxide) ) The photoresist pattern 31 obtained by developing the solution is shown in FIG. 4 (b). Raster scan is performed from the upper left of the figure to the horizontal direction to complete the drawing. In the voltage acquisition area 32, the current 値 is gradually set to the setting 根据 according to the current feedback processing, so the drawing state can be gradually learned as the scanning progresses. In the drawing field 33, the pattern data will be copied in the field 30. The minimum processing size of this pattern is 100 nm. The present invention does not often apply current feedback, but performs it at each predetermined drawing distance, and then obtains the voltage 値 that can obtain the desired current and memorizes it, and only uses 0 N / 0 of the memory voltage 当时 at that time. FF is switched for drawing, so it is possible to provide a pattern drawing device capable of drawing complex and fine patterns at high speed. In addition, the memory of the voltage 値 can also be controlled to be executed at each gradually shorter distance under consideration of the wear of the probe. (Embodiment 2) This embodiment is an example of a pattern drawing apparatus using a plurality of probes for drawing on a photoresist film using FIG. 5. Although the pattern drawing device of this embodiment and the embodiment of FIG. 1 are essentially unchanged, it is actually different from that of FIG. 1 in that the difference is a plurality of conductive probes arranged in a one-dimensional array.

Furthermore, the spring portions 4 1 a and 4 1 d at both ends are connected to the position detection portion 16, so that the photoresist from the probes 4 0 a and 4 0 d can be detected in the same manner as in Example 1. According to these signals, the vertical position of the surface of the layer 8 is shifted according to these signals, and the vertical positions of all the probes 4 〇a-4 0 d are adjusted to the desired values. . Here, the parts common to the two embodiments are given the same drawing numbers. Next, the operation when drawing a pattern using the device of Fig. 5 will be described. First, in the same manner as in Example 1, in order to bring the probes 40 a to 40 d into contact with the photoresist layer 8, the two coarse steps are brought closer together by the Z coarse moving portion 11. After being very close, two independent position feedback loops (consisting of position detection unit 16, control unit 12 and Z drive unit 4 2 a and 4 2 b) are used to automatically control the probes 4 0 a and 4 0 The vertical position of d. Thereby, even if the straight line connecting the front ends of the probes 40a to 40d is not parallel to the surface of the photoresist layer 8, it can be automatically adjusted to be parallel ', so that the probes 40a to 40d can be almost the same. To come into contact with the surface of the photoresist layer 8. The pattern data is prepared for each of the probes 40 a-4 0 d. The pattern data is read by the input section 17.

The pattern data depicted does not necessarily have to be different as shown in Figure 6, but multiple probes can also be borrowed. Draw the same pattern data. In addition, the voltage acquisition area is not necessarily divided into probes. For example, the same voltage acquisition area is scanned only the number of times of the number of probes, and the voltage used for each probe drawing is obtained each time. Although Fig. 5 shows that four probes 40a-40d are arranged in a single unit, the number of probes is not limited to this, that is, the higher the number, the faster the drawing speed. It is also possible to arrange in two dimensions. In this case, the position detection for the vertical position control of the probe is performed by using spring portions connected to three probes which are not on the same straight line. For each signal, three Z drive units are made based on three independent position feedbacks. The displacement can be controlled by the vertical position of the probe. Here, as in the first embodiment, if the drawing is performed using the flattening layer 30 shown in Fig. 3, the drawing can be performed even if the substrate 6 has irregularities.

Description of the invention (The photoresist layer is rotated by 880. Each probe 40 is fed back to adjust the current 値, and the actual drawing is performed by the entry section 17. Each time the same surface is performed. Then, it is driven here by rotation. 'Although the drawing is performed by the voltage application unit a-4 0 d, the pattern data read by the voltage stop feedback processing flowing through each probe at this moment is drawn, and the drawing of a distance of voltage 値 is performed at a certain rotation angle 4 4 moving part 8 2 to make the rotary table 14 to apply a voltage to the voltage storage part 15 between the current 0d and the conductive layer 7 in the pressure storage (corresponding to the storage of electricity in accordance with the input voltage). 'And the voltage memorized by the electric material 値) output can be measured at each probe 40 a-4 0 d, or each time the rotary table 80 is held. In this case, from each probe 40 a But all probes 4 can be performed at the same time (please read the precautions on the back before filling this page). Although the distance drawn at a time is proportional to the distance of the rotation center of 40 d, the voltage 値 measurement of a-4 0 d is therefore Reduces rotation speed during voltage measurement Area for voltage measurement. Rotary stage 80 will move the XY pin 4 a-4 0 d by a certain distance each cycle, so that the concentric circle rotation angle can be drawn to make the probe 40 a radial direction. , A vortex-shaped moving part 10 will be formed, which will make the probe move in the direction of the moving diameter direction. In addition, 4 probes 4 0 d will be moved at a certain speed according to the rotating stage 8 0 4- The number of 4 is not particularly limited. The probes can also be arranged for the second element. The position detection is performed by using the same connection, and the pattern is used for each signal. In the 0th d, but the more the number, the more It can also be used to describe the speed. Although the three independent position feedbacks of the three probes on the straight line of the probe are one at a time. The faster the probe is, the more spring part is used to control the three z. This paper size is in accordance with China National Standard (CNS) A4 (210 X 297 mm) 472279 A7 B7 V. Description of the invention (16) The driving part is displaced to control the vertical position of the probe. It is the same as in Example 2. , Even on the substrate 6 with unevenness, You can use flat (please read the precautions on the back before filling in this page) to draw the layer 30. Since the pattern drawing device of this embodiment can draw the dot pattern corresponding to the data information and address information into a circular shape [Industrial Applicability] If the present invention is used, the current feedback is not always applied, but before the pattern is drawn, a voltage can be obtained by memorizing to obtain the desired current. In other words, the drawing is performed only with the 0 N / 0 FF switching of the memory voltage 当时 at that time, thereby enabling complex patterns to be drawn at high speed. Even higher speed rendering can be achieved by using multiple probes.
