Title: Image forming method and photosensitive material
Inventor: OKAMOTO KAZUYA
IPC: G03F7/033
Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To form a fine pattern while preventing influences of the preceding exposure by using a latent image forming reaction through radicals produced by exposure and by exposing under the presence of a quencher of the radicals. SOLUTION: The light emitted from a light source 1 illuminates a reticle 3 through illuminating optics 2. The light transmitting through the reticle 3 passes through projecting optics 4 and gives a reduced projected image of the reticle 3 on a wafer 6 fixed to a stage 7. The wafer 6 is coated with a photosensitive material 5 containing a radical quencher, or the wafer is exposed to light in a quenching atmosphere. By the effect of the radical quencher or the quenching atmosphere, radicals produced in the first exposure can be almost completely quenched before the second exposure is started, and thereby, the second exposure can be performed in a good state. Thereby, an image of ultrahigh resolution can be formed while eliminating influences of residual radicals.

Abstract: PURPOSE:To obtain a locus equivalent to a load fluctuation time real load locus at the time of setting a constant pressure, by fluctuating a pressure setting signal by a set time delay in a delay element, later than fluctuation of a load setting signal at the time of load fluctuation. CONSTITUTION:A dead time element 44 serving as a delay time element is provided between a load control unit 34 and a pressure control unit 35. Hereat, a load setting signal from a load setting device 38 is inputted in this element 44, and the load setting signal as a reference signal is outputted toward a pressure setting device 41 after a prescribed dead time. Thereby, a timing when the real load starts its lifting at the time of load lifting, can become a timing when the gas turbine inlet pressure detected by a pressure detector 32 starts its rise, so that reducing operation for a fuel flow rate accompanying the lift of a pressure setting value, is not carried out on the gas turbine facility side. Therefore, a phenomenon in which the real load drops temporarily does not appear, and the locus of the real load becomes nearly same as the locus at the time of constant pressure operation.

Abstract: PURPOSE:To form high concentration Sn layer on a plate base surface at a low cost, by applying suspension of Sn powder to the surface of the plate base, surface composed of Pb alloy including no Sb, or by dipping the plate base into the Sn powder suspension and applying heat treatment thereto. CONSTITUTION:A plate base consisting of Pb-Ca alloy is dipped into toluene with Sn powder suspended therein and then pulled up.
