Abstract:
A semitransparent phase shifting mask has, in the periphery of a pattern element area, a light shielding portion which is formed by a semitransparent phase shifting portion and a transparent portion with the optimal size combination. A pattern is formed employing the semitransparent phase shifting mask.
Abstract:
To provide a substrate temperature control system capable of unifying the temperature of the substrate and capable of shortening the temperature elevation time (temperature lowering time), the substrate temperature control system is equipped with a temperature control plate (heating or cooling plate) having a plurality of projections on its surface and acting to set the temperature of the substrate. A chuck mechanism is provided to fix the substrate in contact with a plurality of the projections by chucking the substrate toward the temperature control plate.
Abstract:
Electrical charge accumulation caused by exposure to a charged particle beam during the formation of latent image pattern can be reduced and thus the positional deviation of the pattern by using a bottom-resist layer comprising a radiation-induced conductive composition. Highly integrated semiconductor device can be made easily and in high yields. The positional deviation can further be reduced by exposing a charge particle beam patterning apparatus substantially simultaneously with an actinic radiation such as ultraviolet light, X-ray, and infrared light.
Abstract:
A lithographic method for forming a mask pattern is useful for etching wiring or insulator layers on a substrate. A catalyst generation layer and a latent image formation layer are formed on the target layer prior to application of actinic radiation to activate a catalyst in the catalyst generation layer in accordance with a predetermined pattern. The activated catalyst diffuses into the latent image formation layer to form a latent image, which then serves as a mask pattern for etching the catalyst generation layer, latent image formation layer and target layer. The catalyst generation layer may be formed prior to the latent image formation layer, or vice versa. In another embodiment, the catalyst generation layer is formed prior to the radiation step, but the latent image formation layer is formed after application of the actinic radiation.
Abstract:
A photomask which is suitable for a phase shift method and a method for manufacturing a semiconductor device using the photomask is disclosed. The photomask comprises a transparent area, a translucent area and an opaque are arranged in a particular manner relative to a shifter film. In particular, the different elements are arranged so that the lowering of intensity and the amplitude of a transmitted light in the transparent area caused by an unnecessary peripheral part of a shifter film are smaller than the lowering of the intensity and the amplitude of a transmitted light through a transparent area. This serves to prevent an undesirable influence of the unnecessary peripheral part of so that a shifter film can reading be prevented, and a connected pattern can be formed.
Abstract:
Electrification is suppressed with a water-soluble electrification-suppressing film having an electron conductivity and comprising a polymer resin. A high electrification-suppressing effect which is also high in vacuum can be easily obtained by using the electrification-suppressing film with less contamination.
Abstract:
The present application relates to a method and an apparatus for forming a pattern, in which a plane on which a pattern on a sample is traced is decomposed into predetermined partial regions; the pattern density in each of the partial regions is stored in data storing means as pattern density map data; and the irradiation energy amount of a charged particle beam is corrected on the basis of the pattern density map data to correct shortage and excess in the exposure dose due to roughness and fineness of the the pattern, i.e. the proximity effect. Further, the present application relates to a method and an apparatus for forming a pattern, in which when one or a plurality of layers located under the layer on which the pattern should be formed have patterns, influences of the underlayers on the proximity effect are taken into account.
Abstract:
There is disclosed a method for forming micro patterns in a semiconductor integrated circuit device with high productivity and high accuracy. A photolithography having high throughput and electron beam lithography using a reticle and having relatively high throughput and high resolution are selectively used so as to obtain highest throughput while satisfying accuracy and resolution required for each product/layer. In the case of using the electron beam lithography, a non-complementary reticle and a complementary reticle are selectively used so as to obtain highest throughput while satisfying required accuracy and resolution. Thus, productivity and integration can be improved for the semiconductor integrated circuit device.
