Definitions
- the present invention relates to a semiconductor device and a method for manufacturing the same, and more particularly, a technique for manufacturing a semiconductor device using focus monitoring in a photomask and photolithographic process and image plane tilt monitoring of projection exposure. About.
- FIG. 1 is a conceptual cross-sectional view for qualitatively explaining the relationship between the exposure amount and the pattern width.
- Fig. 1 (b) shows the resist obtained by exposure when the exposure is optimal
- Fig. 1 (b) shows that the exposure is excessive
- Fig. 1 (c) shows the resist obtained by exposure when the exposure is insufficient (under).
- the pattern (1 la-11c) is shown.
- Reference numeral 10 denotes a substrate having a surface coated with a resist.
- Fig. 1 (b) when the exposure dose is excessive (Fig. 1 (b)), a narrower pattern is obtained compared to the case of patterning with an appropriate exposure dose (Fig. 1 (a)).
- Fig. 1 (c) shows a wider pattern is obtained than when patterning with an appropriate exposure dose (Fig. 1 (a)).
- the line width of the pattern formed on the semiconductor substrate is monitored, and the result is fed back to the exposure amount control. It is common to monitor the exposure by a procedure.
- Fig. 2 is a conceptual diagram for qualitatively explaining the relationship between the focus (deviation) and the cross-sectional shape of the pattern.
- Fig. 2 (a) shows the case where the focus amount is optimal (best'focus).
- 2 (b) shows a resist pattern (21a-21c) obtained by exposure when the amount of focus is excessive (ono-focus), and
- Fig. 2 (c) shows a case where the amount of focus is insufficient (under-focus).
- the shape is shown.
- the top edge is the bottom in the best focus.
- a trapezoidal pattern that is shorter than the side is obtained, whereas a trapezoidal pattern with the top side longer than the bottom (reverse) is obtained in the case of overfocus (Fig. 2 (b)).
- FIG. 3 is a flowchart for explaining an outline of an example of a conventional focus monitoring method.
- the medium force of a pattern formed in a semiconductor device during the manufacturing process is also set to the focus condition. It is easy to be affected, and a method is adopted in which a pattern is identified and the line width of the pattern is measured. Specifically, the product is first exposed (step S301), and the force is also easily affected by the focus condition, and the pattern is selected and its line width is measured (step S302).
- step S303 The pattern line width is compared with the design value (step S303), and if the design value is as it is (step S303: Yes), the product is delivered to the next process (step S309). On the other hand, if the pattern line width deviates from the design value (step S303: No), it is determined that the conditions such as exposure amount and focus are not appropriate, so the exposure amount and focus value are used as parameters. The exposure is performed again by setting new exposure conditions (step S304). Then, an appropriate exposure amount and focus value are obtained (step S305), and it is determined whether or not the exposure condition in step S301 is deviated from the proper focus (step S306).
- Step S306 If it is determined that the focus condition is appropriate! (Step S306: Yes), the cause of the focus shift is investigated and specified to correct the focus condition. (Step S307), the product is delivered to the next process (Step S309). On the other hand, if it is determined that the force condition is appropriate (step S306: No), it is determined that the exposure value is also deviated from the appropriate value, and the exposure value is corrected (step S308). To the next process (Step S309).

It is difficult to determine whether there is a force deviation, and this requires the troublesome procedure of adjusting to the appropriate focus condition by using a wafer with the exposure amount and focus value as parameters. is there. In other words, with the conventional focus monitoring method, it is difficult to quickly detect the “shift” even if the focus condition deviates from the appropriate value!
