Could a hypernova form an intermediate mass black hole?

Supernovae, including hypernovae, are expected to form stellar black holes. The stars that eventually become supernovae (or hypernovae) don't have the mass requird for an intermediate-mass black hole. It is not yet entirely clear how intermediate-mass black holes or supermassive black holes form; perhaps they start as a stellar-mass black hole and gather more mass, or perhaps a larger object, such as a gas cloud, somehow collapses directly into a gigantic black hole.
