Hello, Vaibhavmaskar.:-D

'to have become (=to have + past participle)' is called "the perfect infinitive".
In this case, 'become' is the past participle of the verb 'become'. It's not a noun.

I hope my response will be of some help to you.

You've done nothing wrong.
You don't have to say/feel sorry.:-D
