Title: Display device and production thereof
Inventor: MORI KOJI
IPC: H01L29/78
Filed: 1990-11-20
Abstract: PURPOSE:To form the high-quality display device on a low-cost substrate by having amorphous silicon thin-film transistors for an active matrix and polycrystalline silicon thin-film transistors for peripheral driving circuits on a heat resistant plastic film. CONSTITUTION:Gate electrode parts 2 of the active matrix part are formed on the polyimide film 1 and insulating films 3, 3' are formed. The active matrix has the function as the gate substrate film 3 and the peripheral driving part as the underlying protective film 3'. After the a-Si film 4 is formed, an oxide film 5 is selectively formed in the peripheral driving part alone and n<+> contact holes 6 are formed. The n<+> of this time functions as gate electrode parts 6' and after the gate electrodes 6' and gate oxide film 5 are etched only in the peripheral driving part, impurity diffusion and activation are executed by a laser or plasma. The high-quality display device is formed on the low-cost substrate in this way.

Abstract: PROBLEM TO BE SOLVED: To regenerate a used acid catalyst resin into a sufficiently active one for reducing the amount of the cation exchange resin to be disposed of, by treating the used catalyst with a sulfonating agent and separating the catalyst resin from the sulfonating agent. SOLUTION: A used acid catalyst resin, namely a sulfonic-acid-functional cation exchange resin, used as an etherification catalyst is treated with a sulfonating agent comprising sulfuric acid having a concentration of 85wt.% or above or oleum having a sulfur trioxide content of 10-40wt.% at 60-150 deg.C under a pressure of 100-200kPa for 0.5-6hr, and the mixture is separated into the acid catalyst resin and the sulfonating agent. Thus, the used catalyst can be regenerated into one substantially freed from contamination with a polymer, contamination with nitrogenous substances and influences by desulfonation and having activity and life equivalent to those of a fresh acid resin catalyst.
