Simple, just negate the plane's normal.
plane{y,0} becomes plane{-y,0}
If the plane ton't pass through the origin, like this:
plane{y, 10}, then you need to also negate the distance like this:
plane{-y, -10}

You can also use inverse.

This construction is OK
You start with the base object, then you remove the sphere and the plane.

This one is not, at least, it's not recomended...
