Problems solved by technology
In view of the current technical level, the situation of the photolithography process is that it is difficult to form fine patterns below 70nm on the substrate due to the interference of light
In addition, there are disadvantages in that the use of expensive equipment such as exposure equipment leads to an increase in initial investment costs and a skyrocketing price of high-resolution masks as patterns are advanced to reduce efficiency.
The actual situation is that there has not been an ink composition that can satisfy all the above characteristics before, and the development related to this has become an urgent demand
