Title: Semiconductor wafer grindstone
Inventor: SATO ISAO
IPC: B24D3/00
Filed: 1986-12-01
Abstract: PURPOSE:To make it possible to continuously use one grindstone for finishing a wafer having a predetermined thickness and a predetermined surface-roughness by integrally incorporating rough-grinding and finishing grindstones with each other so as to arrange them in a ring-like pattern. CONSTITUTION:When a wafer 6 sucked and secured to a chuck table 7 is advanced toward the center from the outer peripheral surface of a grindstone, the wafer 6 is at first rough-ground by a rough-grinding grindstone part 1 in the outer peripheral part of a grindstone to a depth of DELTAt1. Further, the rough- ground surface is then subsequently ground by a finishing grindstone 2 by DELTAt2 so that the thickness of the wafer 6 then has a value such as t-(DELTAt1+DELTAt2), and the wafer is finished having a surface-roughness corresponding to the particle size of the finishing grind stone 2.

Title: Method for measuring glass transition temperature
Inventor: SASAKI HIDEYUKI
IPC: G01N21/3563
Filed: 1989-11-02
Abstract: PURPOSE:To make it possible to perform the highly accurate measurement of the glass transition temperature in an amorphous macromolecular material having the partial structure of O = C - C - X group (X is halogen element) in a chemical structure on the spot of the manufacturing process by measuring the change in intensity ratio of the absorption peak of the infrared-ray absorbing spectrum of this material with respect to the temperature. CONSTITUTION:At first, infrared rays 2 from a light source 3 is applied on a sample to be measured 8 which is kept at a specified temperature through a Michelson interferometer 4 and a first reflecting mirror 5. The infrared rays reflected from the sample 8 is guided to a detector 7 through a reflecting mirror 6. The peak intensity of the infrared-ray absorbing spectrum is measured. A peak-intensity ratio R is obtained based on the measured peak intensity. A series of measurements are performed by changing the heating temperature. The change in peak intensity ratio R with respect to the heating temperature is obtained. The temperature where the value of R starts changing is obtained with respect to the change in peak intensity ratio R with regard to the heating temperature obtained in this way. Thus, the glass transition temperature of resist can be obtained accurately.
