    摘要: A mask material which is the same as that of a wafer to be exposed is prepared (step Q1), and the proximity effect correction dose for mask-writing is operated. Then, a resist film of the mask material is exposed by a pattern accompanying a correction dose twice the proximity effect correction dose in mask-writing at the same accelerating voltage as in wafer-exposing (step Q2). Next, the resist film is developed to form a resist film pattern, and the mask material is etched by using the resist film pattern as a mask, whereby a mask is prepared (step Q3). Thereafter, by using this mask, the resist film on the wafer is EB-exposed without proximity effect correction (step Q4). According to the present invention, the time required for calculation processing is shortened and the calculation accuracy is improved.

    摘要: There is disclosed a vehicle-mounted device with a sleep function for use in a road-to-vehicle communication system. After having indicated a switching period T1 and reception frequencies F1, F2 to a frequency switching controller, a controller stops operation of an internal counter, and enters a sleep mode until it cancels the sleep mode in response to a detected signal from a receiver. While a vehicle with the vehicle-mounted device is running outside of a communication range of a road radio unit installed at a toll gate or the like, the frequency switching controller independently performs a frequency search process on an RF module, and the controller is in the sleep mode. Therefore, the vehicle-mounted device has a relatively low power requirement.

    摘要: The present invention provides spot-illumination of a specific size having sufficiently homogeneous light intensity distribution, with a small and inexpensive apparatus. A lighting assembly condenses the light from light source 1 with condensing-reflecting member 2. An optical integrator 3 receives at its one end the light via condensing-reflecting member 2 and emits from the other end after making the light intensity distribution homogeneous A projection lens system 4 projects the emitting surface of optical integrator 3 onto an emitted surface. By shifting the relative positioning between the lighting assembly and the substrate 11, and adjusting the distance between the substrate 11 and the mask 12, which stores a pattern to be formed, a specified area of the exposure surface 11a is scanned and exposed to have a mask pattern transcribed on the exposure surface 11a.
