Assuming the FT is missed, it's an Intentional Personal Foul. IF the FT was made, the ball is dead, so it's an Intentional Technical Foul.

And, in either case, if the contact was somehow before the FT Ended (see the rule on FTs to determine this), both are IP fouls.

Rule 4 is your friend.

The above answer by Bob is correct.
You need to determine whether the FT was still in progress or over for the first attempt. For the second, you do the same, but realize that the ball remains live on an unsuccessful attempt.
