Title: Noise figure measuring method
Inventor: HARA KAZUYA
IPC: G01R29/26
Filed: 1981-06-12
Abstract: PURPOSE:To shorten a measuring time, and also to elevate its accuracy, by inputting a prescribed high frequency signal, adjusting an input/output tuning circuit of a measuring circuit network, and after that, providing a prescribed noise generating source output. CONSTITUTION:When a switch SW is connected to the side (a), a high frequency signal is inputted to a high frequency amplifying element to be measured DUT from an oscillating circuit OSC. In this state, an automatic tuning circuit CONT varies input side variable capacity C1 and output side variable capacity C2 alternately so that output voltage VOUT becomes maximum by such circuits as detecting, amplifying, sample-holding comparing, servo-controlling, etc. Also, control voltage CV1 and CV2 by which the maximum output voltage can be obtained are held. Subsequently, a noise figure is derived by changing over the switch SW to the side (b), connecting a noise diode ND to an input terminal IN, turning on and off the noise diode ND, and reading the respective noise levels by an NF operating circuit NF.

Abstract: PURPOSE:To coat resist over the entire surface of a coated surface to a film thickness approximately uniform by a method wherein the coated surface is turned at a fixed speed of rotation, after the surface is turned at a speed of rotation larger than the fixed one corresponding to a desired film thickness. CONSTITUTION:After a wafer 4 is chucked by a vacuum chuck 2, the suitable amount of resist 5 is dripped.

Therefore, it is turned at a speed of rotation larger than the fixed one, e.g. 6,500r.p.m. till t2' seconds. Meanwhile, unnecesary resists 4 are discarded from the surface 3 of the wafer 4 in a short time. Afterwards, it is turned at the fixed speed of rotation corresponding to a uniform desired film thickness, e.g. 4,000r.p.m. till t3' seconds, and accordingly a desired resist film 6 is obtained.
