    Abstract: PURPOSE:To perform pattern machining of a conductive layer with a small spacing using a general exposure device, for example, reduce the cell area of a memory cell for SRAM and increase integration. CONSTITUTION:A resist auxiliary layer 18 functioning as one portion of a resist film when performing etching machining a conductive layer 16 is formed on a conductive layer 16 which should be subjected to pattern machining. After that, the resist auxiliary layer 18 is subjected to etching machining to a specific first pattern by a first resist film 20. Then, a second resist film 22 with a specific second pattern is formed on the surface of the conductive layer 16 where the resist auxiliary layer 18 is eliminated near the first pattern of the resist auxiliary layer 18. Then, the conductive layer 16 is subjected to etching machining with the resist auxiliary layer 18 of the first pattern and the second resist film 22 of the second pattern as masks, thus obtaining a conductive layer with a micro-pattern.

    Abstract: PURPOSE:To eliminate an insulating film outside a trench, in the manufacturing method of a semiconductor device wherein a trench formed on the surface part of a semiconductor substrate is filled with an insulating film by bias ECRCVD. CONSTITUTION:A resist film 6 for flattening is formed on the surface of a semiconductor substrate. The resist film 6 for flattening is eliminated until the upper part of an insulating film 5a outside a trench is exposed. The resist film 6 for flattening use is used as a mask, and the insulating film is etched. An insulating film for flattening is eliminated until the upper part of the insulating film outside the trench is exposed. The insulating film inside the trench is used as a mask, and etching is performed in this state, so that only the insulating film outside the trench can be completely eliminated.

    Abstract: PURPOSE:To form a minute contact hole with a high density using self-alignment techniques by forming a wiring groove in an interlayer dielectric film by means of etching techniques using, as a mask, a resist film used to produce a groove, by preparing a resist film used to produce a contact hole, and by etching a substrate using both resist films as a mask. CONSTITUTION:An interlayer dielectric film 10 is selectively etched using a resist film 11 as a mask, and a wiring groove 12 is then formed in the interlayer dielectric film 10. With the resist film 11, used to produce a groove, remaining, a resist 13 used to produce a contact hole is prepared. Using these resist films 11 and 13 as a mask, the interlayer dielectric film 10 is etched, whereupon bit contact holes 15 are formed. With this arrangement, even if areas unmasked with the resist films 11 and 13 are large, there the contact is ensured. Therefore, it is possible to achieve a minute contact hole with a high integrity in excess of the marginal resolution of a photolithography.

    Abstract: PURPOSE:To enhance the alignment accuracy by performing resist removal only on the exposure pattern for measurement of alignment error provided in an exposure mask pattern, correcting the error in position setting, and then performing pattern exposure to the resist. CONSTITUTION:An exposure pattern 4 for measurement of alignment error is provided on a reticle, which performs pattern exposure to a resist 3 formed on a substrate 2 having a ground substrate pattern 1, and the intensity of exposure laser beam is increased to remove resist 3 only from the pattern 4. The error data is obtained from the positional relation between this pattern 4 and above-mentioned pattern 1, and on the basis thereof the relative position setting error of the exposure mask pattern with the substrate is corrected, and exposure of device pattern by reticle is made to the resist 3. This provides high accuracy alignment.

    Abstract: PURPOSE:To form a resist pattern by using a fine pattern of high resolution, high accuracy and high definition by a method wherein, for a two-layer resist method, a second photoresist layer as an upper layer is composed of a negative- type photoresist which can absorb the deep UV light of a short wavelength considerably. CONSTITUTION:When a photoresist pattern is formed on a substrate 1 where a stepped part 2 is formed on the surface, a first photoresist layer 11 which is photosensitive to far ultraviolet rays is formed in such a way that its surface 11a becomes nearly flat while the stepped part 2 is filled: the far ultraviolet rays are absorbed on this surface. In addition, a second negative-type photoresist layer 12 which is photosensitive to the far ultraviolet rays is formed: this second photoresist layer 12 is exposed boy the far ultraviolet rays, and is developed; a pattern is formed; the first photoresist layer 11 is exposed by the far ultraviolet rays by making use of the second patterned photoresist layer 12 as an optical mask, and is developed: a pattern is formed. By this setup, the resist pattern of high accuracy and high definition can be formed.

    Abstract: PURPOSE:To form the microscopic exposure pattern having excellent degree of sharpness by a method wherein the exposure pattern for a photoresist is divided into the sets of pattern having the interval layger than the minimum width of resolution line, and a reduction projection exposure operation is performed respectively on the pattern of each set which is divided as above. CONSTITUTION:The every other one of the stripe-like exposure part S for a photoresist film 2 is formed into a set, and it is divided into the first and the second exposure patterns 8A and 8B, they are superposed by performing an exposing operation twice, and an exposure pattern 8 is formed on the photoresist film 2 by conducting an exposing operation. In this example, as the first and the second exposure patterns 8A and 8B, on which an exposure part S having the width W is arranged leaving the interval 2D+W respectively, have the same pattern substantially, a magnified optical image with which either of the exposing patterns 8A and 8B will be formed is used as an original pattern when a pattern exposing operation is performed. When an exposure pattern 8 is going to be formed, the first and the second exposing operations are performed respectively.

    Abstract: PURPOSE:To enable a resist layer with a fine pattern and excellent plasma resistance to be formed by a method wherein a semiconductor is successively coated with a photoresist layer and specific film, and after irradiating the film with laser beams to provide it with transmittance, overall surface is irradiated with specific light to expose the photoresist layer. CONSTITUTION:A semiconductor substrate 1 is coated with a resist layer 2 with high plasma resistance sensing specific light (ultraviolet rays) 6 and the resist layer 2 is further coated with an image forming film 3 with the transmittance to the light 6 by irradiating it with laser beams 5. Then, the film 3 is irradiated with laser beams 5 through the intermediary of masks 4 of specific pattern to provide the irradiated part 3a with transmittance and then the overall surface is irradiated with the light 6 using the film 3 as a mask to expose the photoresist layer 2. Through these procedures, the photoresist layer 2 is exposed conforming to the mask pattern of film 3 and after development, etching resist layer 7 with high precision fine pattern can be formed on the semiconductor substrate 1 so that high plasma etching resistance may be provided later due to the high plasma resistance of the resist layer 7.
