Definitions
- the present invention is based on the priority claim of Japanese Patent Application No. 2013-081409 (filed on Apr. 09, 2013), the entire contents of which are incorporated herein by reference. Shall.
- the present invention relates to a semiconductor device, and more particularly to a semiconductor device having a layout pattern of wirings electrically connected to a contact portion.
- the contact hole pattern tends to be more difficult to optically reduce the pitch than the wiring pattern, and the contact portion 121 is arranged on the periodic pattern such as the wirings 101 and 102 in FIG.
- the wirings 101 and 102 are generally arranged and connected at a double pitch.
- the contact part may be opened by stepping off the wiring pattern only by arranging every other contact part with respect to the wiring, and the contact resistance increases.
- the terminal portion of the wiring 102 not connected to the contact portion 121 is removed from adjacent wirings, and the wiring 101 connected to the contact portion 121 is removed.
- the contact part can be prevented from being stepped off, and the pitch of the wirings 101 and 102 can be afforded, so that the wiring interval is also large.
- it was enlarged to avoid a short circuit for example, Patent Document 1).
- a bridge portion 114 in which the terminal portions of the wirings 101 and 102 having the same potential are connected is provided, and the contact portion 121 is disposed in the bridge portion 104. This avoids stepping off the contact portion from the wiring and short-circuiting between the wirings 101 and 102 (see, for example, Patent Document 2).
- the numerical aperture / projection of the illumination optical system viewed from the pupil of the projection optical system The numerical aperture of the projection optical system as viewed from the pupil of the optical system) or illumination such as a cross pole must be used.
- the wiring is drawn at a pitch near the resolution limit.
- the nominal condition is as shown in FIG.
- All of the portions (resolution portion 131) corresponding to the wiring (101, 102 in FIG. 6) and the lead-out wiring portion (111 in FIG. 6) are resolved, but under the defocus condition, as shown in FIG.
- the resist loss becomes large, and the focal depth worsening portion 132 in which the partial focal depth corresponding to the lead-out wiring portion (111 in FIG. 6) is remarkably deteriorated (decreased) is formed. Since there is little resist remaining under the defocus condition, the probability of pattern disappearance in the etching process increases. This is because three-beam interference (three-wave interference) using the periphery of the lens. Details are as follows.
- the 55 nm L / S diffraction pattern passes only the 0th-order light and the 1st-order light through the pupil, and forms an image on the resist surface by two-beam interference as shown in FIG. Since the two-beam interference has the same phase in the resist depth direction, a high DOF (Depth of Focus) can be obtained.
- the minimum pitch is about 110 nm
- the difference between the inner ⁇ and 0.58 can be increased with respect to the outer ⁇ 0.94 (coherence factor), so that effective light also enters the 220 nm pitch. Therefore, although the DOF was weak, a large drop could be avoided.
- the angle of incidence on the resist increases as shown in FIG. 17 (the difference can be seen when compared with 55 nm L / S in FIG. 15).
- the phase difference on the resist becomes very large as shown in FIG. 18, so that almost no DOF can be obtained.
- the inner ⁇ cannot be reduced and the difference from the outer ⁇ cannot be expanded in order to resolve the 80 nm pitch, a large drop in the depth of focus occurs in a region near 1.5 times to 2.3 times the minimum pitch. It cannot be avoided.
- the graph of FIG. 19 is obtained by optimizing the illumination required for resolution at the minimum pitch of 80 nm and 110 nm individually, and investigating the DOF of the pattern with the pitch varied with each illumination.
- the mask dimension is adjusted so that the simulation CD (Critical Dimension) is 1: 1.
- the simulation was performed with an optical image, and the threshold value used was a value with which the simulation CD was 1: 1 when the minimum pitch mask was 1: 1 L / S.
- the DOF satisfies the specifications even at a double pitch of 220 nm.
- the minimum 80 nm pitch it becomes the worst when the double pitch is 160 nm (meaning that the conventional technology cannot cope). For this reason, the pattern is drawn with a strict pitch.
- the illumination shape B there is a region where the depth of focus is very small centering around the double pitch (160 nm) of the minimum pitch.
