る。In the above prior art, since the sample is directly provided with the position detecting mark, the drawing area on the sample is limited. Furthermore, when the position detection mark is detected, the area around the main mark is also drawn, resulting in a lack of productivity such as narrowing the semiconductor chip size and reducing the number of chips to be acquired. For deformation due to thermal expansion, it is possible to make the sample holding device including the sample stand by on the drawing stage and wait until the temperature of the sample stabilizes, but it takes several hours until the temperature stabilizes. The operation rate of the equipment is reduced.

By arranging at the apex of the substrate 12 as described above, the amount of deformation or rotation is maximized, and more accurate change in relative position can be detected, which is preferable. However, it is necessary to prevent the displacement of the supporting position by arranging it at the acute angle position of the substrate 12. Therefore, as shown in FIG. Prevent.

By arranging it on the contactor 23 arranged on the side, it is possible to eliminate the influence of the elongation of the spring element 21.

However, in the drawing portion of an electron beam drawing apparatus, there is no high-temperature portion that is affected by radiation, and all the heat is generated. Considered to be conduction. Therefore, the substrate 1
2 may be constituted by a temperature measuring means such as a thermocouple, or as shown in FIG.
By incorporating the temperature measuring means 24 in the substrate 1,
Two accurate temperature measurements are possible. A thermocouple or the like is used as the temperature measuring means 24.

(503)。Next, the correction method will be described. FIG. 5 is a flowchart showing the procedure of the sample position correcting method according to the embodiment. The correction computer 103 first sets one of the position detection marks 22 as the origin, detects the position of the origin and the relative position of the remaining position detection marks 22 from the origin (501), and determines whether there is a change in the inter-mark distance. A determination is made (502). If there is no change in the distance between marks, the substrate 12
Since no deformation has occurred in the image, the image is drawn without correction (503).

Next, the presence or absence of temperature fluctuation is determined (504). The temperature is measured when the mark is detected. If the temperature has changed, the substrate 12 has undergone thermal deformation. Therefore, the thermal expansion amount is calculated from the temperature difference based on the intrinsic thermal expansion coefficient of the substrate 12, and the correction amount for thermal deformation is obtained (505). If there is no temperature change, step 505 is skipped.

いてスリップ量を算出する(507)。Next, it is determined whether or not the sample is shifted due to the movement of the stage (506). When the shift occurs, parallel movement and rotation occur due to the slip of the sample. Therefore, the on-stage mark 15 of FIG. 2 is used as the position of the origin and based on the positional relationship with the individual position detection marks 22. Then, the slip amount is calculated (507).

ことができるので、補正して描画する(509)。Next, a correction amount for correcting the change in the distance between the individual position detection marks 22 is obtained (508).
This deformation is a stress deformation due to an external force such as a support pin,
By measuring the change in the distance between the individual position detection marks 22, it is possible to know what kind of stress is acting, and the correction amount of the deformation due to stress can be calculated from this, so Draw (509).

きる。The correction amount can be obtained at any time after the distance between marks is measured by calculation such as simulation. However, the processing speed of the electron beam drawing apparatus is high, and it is difficult to obtain the correction amount during drawing by the above method. Therefore, by obtaining the correction amount from the change in the distance measured in advance and constructing the correction amount database 104, the correction amount can be immediately obtained from the change in the measured distance. The correction amount database 104 can be similarly constructed for the temperature change.
【0026】以上の方法によって、各々の補正量を求

変形による影響を受けない正確な描画が可能になる。By the above method, each correction amount is obtained, and these are combined and corrected at the time of drawing,
Accurate drawing is possible without being affected by deformation.

One of the two is set as the origin, and the relative displacement of the remaining position detection marks 22 is detected from the origin to obtain the correction amount. However, even if the reference position detection mark is arranged on the holder 11 or the position detection mark 15 is provided on the stage 14, the same effect for correcting the deformation of the substrate 12 can be obtained.

である。The more the number of times the position detecting mark 22 is detected, the more accurately the change can be measured. However, considering the time constant of the temperature change of the holder 11 and the deformation of the substrate 12 due to the heat transmitted from the stage, the change is performed for each drawing pattern. Is good. As a result, it is possible to reduce the number of detections and increase the production efficiency.

A sample position correcting method for correcting a drawing position according to a change in the sample position when an electron beam of an electron beam drawing apparatus is deflected to draw on the sample, wherein a contact point with the sample is set. A sample position which is provided and detects the inter-mark distance of a plurality of position detecting marks capable of changing its own position, and calculates the amount of stress deformation from the inter-mark distance to obtain the change of the sample position. Correction method.
変形量を計算して前記試料位置の変動を求めることを特
徴とする試料位置の補正方法。5. The method for correcting the sample position according to claim 4, wherein the temperature of the sample is measured, and the amount of thermal deformation of the sample is calculated from the temperature difference to obtain the variation of the sample position.
