An apparatus and method for detecting defects on a specimen includes an illumination optical unit which obliquely projects a laser onto a region which is longer in one direction on a surface of a specimen than in a transverse direction, a table unit which mounts the specimen and which is movable, a detection optical unit which detects light from the specimen illuminated by the laser with an image sensor while the table is moving, and a signal processor. The signal processor processes a signal outputted from the image sensor of the detection optical unit and converted to a digital signal and extracts defects of the specimen by comparing the converted digital signal with a reference digital signal. A display unit displays information of defects extracted by the signal processor.

Inspection method, apparatus, and system for a circuit pattern, in which when various conditions which are necessary in case of inspecting a fine circuit pattern by using an image formed by irradiating white light, a laser beam, or a charged particle beam are set, its operating efficiency can be improved. An inspection target region of an inspection-subject substrate is displayed, and a designated map picture plane and an image of an optical microscope or an electron beam microscope of a designated region are displayed in parallel, thereby enabling a defect distribution and a defect image to be simultaneously seen. Item names of inspecting conditions and a picture plane to display, input, or instruct the contents of the inspecting conditions are integrated, those contents are overlapped to the picture plane and layer-displayed, and all of the item names are displayed in parallel in a tab format in the upper portion of the picture plane of the contents. When a desired item name is clicked, the picture plane is switched and the contents corresponding to the clicked item name are displayed.

The present invention relates to a cubic parking apparatus vertically formed with parking spaces in a multi-stage fashion to move a car in and out of the parking space through a pallet, in which guides and lateral guides are provided on the parking spaces and a carriage of an elevator, and a transfer device for laterally moving the pallet is provided on the carriage whereby when the pallet is delivered between the carriage and the parking space, a great torsional moment is prevented from being loaded in the carriage to simplify a construction of an elevator device. There is provided a cubic parking apparatus in which a turning device is provided which can be moved forward and backward in an approximately horizontal direction with respect to the carriage passing path, whereby a home position for moving the carriage above and below a position at which the turning device is disposed to move a car in and out of the parking space can be disposed on a suitable story, and parking spaces can be effectively secured.

Photosensitive resist material is coated on a substrate and exposed and developed to form a resist pattern. The surface layer of sidewalls and a top wall of the resist pattern is etched by plasma of a mixture gas of a first gas and an SO2 gas, the first gas being at least one gas selected from a group consisting of He, Ne, Ar, Xe, Kr, CO, CO2 and N2. Resist pattern deformation and pattern collapse can be prevented while the resist pattern shrinks.

A semiconductor device is disclosed that includes a semiconductor substrate, a device region disposed at a predetermined location of the semiconductor substrate, and a shallow trench isolation region that isolates the device region. The shallow trench isolation region includes a trench, a nitride film liner disposed at an upper portion of a side wall of the trench, and a thermal oxide film disposed at a lower portion of the side wall of the trench. The shallow trench isolation is arranged such that the width of a second portion of the shallow trench isolation region at which the thermal oxide film is disposed may be wider than the width of a first portion of the shallow trench isolation region at which the lower end of the nitride film liner is disposed.

The semiconductor device fabrication method comprises the step of forming a first insulation film 14 over a semiconductor substrate 10; the step of forming a semiconductor film 16 over the first insulation film 14; the step of forming a resist film 20 over the semiconductor film 16; the step of forming openings 21 in the resist film 20; the step of etching the semiconductor film 16 with the resist film 20 as the mask; the step of etching the first insulation film 14 with the semiconductor film 16 as the mask; and the step of etching the semiconductor substrate 10 with the first insulation film 14 as the mask to form trenches 22 in the semiconductor substrate 10. Silicon nitride film is patterned, using a mask of polysilicon film, whereby the silicon nitride film can be etched with high selectivity to the polysilicon film. Accordingly, a good pattern of the silicon nitride film can be formed. Even when micronized trenches are formed in a semiconductor substrate with silicon nitride film as a mask, the trenches can be formed in a required configuration. Thus, good element isolation regions can be formed, further micronized.
