A liquid crystal display panel and fabricating method thereof. The present invention relates also to a process for preparing -2-4-piperazin-1-yl-ethoxyacetamide and -2-4- piperazin-1-yl-ethoxyacetamide by chemical resolution of a mixture. A cobalt silicide film having a necessary thickness can be ensured at the bottom of the contact hole. The optimization module receives a second performance indicator set for a second instance of the time period set.
