A photolithographic method for fabricating a pattern which includes a line and a hook-up pad in a semiconductor device, such that the line and the hook-up pad are self-connected to one another by spacer deposition that mitigates a process control issue, and without being misaligned or short circuited. This is achieved by illuminating water flowing upward using a light source directing its light output upward through the water. The fiber-alginate mixture or compound is used in forming a mold, which may be used in casting directly from the human body. The feeding of the first reactive gas includes feeding a second reactive gas, purging the second reactive gas, feeding the third reactive gas, and purging the third reactive gas, and repeating the aforementioned steps a second plurality of times. The connector is provided on the electric pump for connecting an external power.
