The present invention relates to a micro-injecting devicenand a method of manufacturing the same. According to thenpresent invention, a liquid chamber barrier layer and anfirst organic film layer are formed of solution includingna soft polyamide acid. The soft polyamide acid solutionnis dried and heat treated under an appropriate conditionnto harden. When the soft polyamide acid solution isnfurther treated at 280 to 300°C and pressure of 0.5 to 2nkg/cm 2 , the soft polyamide acid solution acts as annadhesive. Accordingly, the liquid chamber barrier layernand the first organic film layer of the membrane whichnare based on and made of the soft polyamide acidnsolution, can be tightly combined with other constructionnwithout the combination progressive layer. |
