We particularly focus on the transition stage when the isolated SNe remnants gradually combine to form a superbubble. We find that when the SN rate is high ($\\nu_{\\rm sn}\\sim 10^{-9}$ pc$^{-3}$ yr$^{-1}$), the merging phase lasts for $\\sim 10^4$ yr, for $n=1\\hbox{--}10$ cm$^{-3}$, and the merging phase lasts for a longer time ($\\sim 0.1$ Myr or more) for lower SN rates ($\\nu_{\\rm sn}\\le 10^{-10}$ pc$^{-3}$ yr$^{-1}$).
