may be removed securely and the insulation film in the fuse region may be left in a specific film thickness. If the stopper film is formed in a size larger than that of the fuse region, a portion of the stopper film is left in a frame-like form.
Currently, a method of forming the first conductive film pattern of the stopper film and the LSI wiring upon fabricating of a semiconductor device having a fuse has been proposed.
However, if the first conductive film pattern is formed of aluminum alloy like the second and third conductive film patterns, the stopper film is formed of aluminum alloy at the same time as when the LSI wiring is formed. Thus, when the stopper film is removed by dry etching, the portion of2018–19 Principality Premiership

The 2018–19 Principality Premiership was the third season of the new format of the Principality Premiership, the top tier of club rugby in Wales run by the Welsh Rugby Union. It was contested by sixteen Welsh clubs following an expansion from twelve teams at the start of the 2016–17 season. The 2018-19 season saw the end of "ring-fencing" and relegation returned for this season with four teams being automatically relegated to the 2019–20 WRU Championship and a fifth team avoiding relegation by winning a playoff.
