We present a formalism based on the functional Schr”odinger equation to

analyse time-dependent tunneling in quantum field theory at the semi-classical

level. The full problem is reduced step by step to a finite dimensional quantum

mechanical setup and solved using the WKB approximation. As an example, we

consider tunneling from a homogeneous oscillating initial state in scalar

quantum field theory.
