IPC: H01L21/324
Filed: 1977-10-24
Abstract: PURPOSE: To prevent the fusing in the heat treatment process and to increase the working efficiency by giving the heat treatment to a number of semiconductor wafers to one surface of which the lapping process is given with the etching process given to the other surface respectively while piling them in opposition of the lapping and etching surface.  
     CONSTITUTION: The lapping process is given to one surface of semiconductor wafer 4 to cause micro unevenness, and the other surface is made smooth through the etching process. Then SiO 2  film 5a and 5b are coated on the etching and lapping surfaces respectively with opening 6a and 6b drilled, and the impurity is deposited within the opening to form the isolation region through diffusion within wafer 4. Then these wafers 4 are piled on each other in many units with film 5a and 5b opposed to each other and then placed on the support board for the heat treatment. Thus the wafers undergo the heat treatment in the atmosphere of N 2  or the like, and the isolation region is formed through diffusion. In this way, the mutual adhesion can be avoided to the adjacent wafers since the unevenness exists on the surface of film 5b opposing to the lapping surface

Filed: 1995-04-28
Abstract: PURPOSE: To measure the contaminability of a sample in a short time by allowing contaminants to adhere to the sample in an arbitrary time cycle and arbitrary temperature cycle while the sample is irradiated with light in an arbitrary cycle. CONSTITUTION: A sample to be evaluated composed of a plastic film sheet, etc., is irradiated with light from an artificial contamination-accelerating light source, such as the xenon arc lamp, etc. Each irradiating cycle is composed of a no-irradiation period of 0.1-100 hours and irradiation period of 0.1-100 hours including always irradiation. While the sample i.s irradiated, the temperature of the sample is repeatedly raised and lowered within a temperature range from -50 deg.C and 100 deg.C in an arbitrary cycle including the temperature rise and drop resulting from the irradiation. While the sample is maintained under such a condition, contaminants peculiar to the using area of the sample adhere to the sample by showering a suspension or solution containing the contaminants on the sample.  Therefore, the contaminated state of a plastic material, etc., under an actual using state (e.g. outdoor exposure) can be measured in a short time.
