In this sentence:
The Internet has become mission critical for many institutions today.
1- In the case of has become, we should use of has + PP of the word. Is the become PP of become!?
2- Why we didn't use the critical mission instead of mission critical in the sentence? Are they apart from each other, that is, mission, critical for…?
Thanks.

Yes, become is the past participle of become. It is exactly like come, with be- added: I (be)come, I (be)came, I have (be)come.
Mission critical (often hyphenated, particularly in attributive position, a mission-critical resource) is a very common phrase these days. It means critical to the mission, i.e. essential in order to accomplish the mission. Your rewrite would miss the sense, implying that the Internet is the mission for these institutions, when in fact the Internet is critical to the various missions these institutions pursue.
