Micro-injecting device

摘要

The present invention relates to a micro-injecting device in which a cohesion promoting layer is formed between a protective layer and a heating chamber barrier layer. The cohesion promoting layer is formed using y-aminopropyltriethoxysilane. The cohesion promoting layer is capable of enhancing the cohesion of the protective layer and the heating chamber barrier layer and thereby enhancing the general injecting performance of the micro-injecting device. <IMAGE>
