  The existence of a minimal length is predicted by theories of quantum gravity
and it is generally accepted that this minimal length should be of the order of
the Planck length and hence can be observed in high energy phenomenon. We study
the implications of the presence of the minimal length on the Klein-Gordon
filed with {\phi}4self-interaction. Considering the process of spontaneous
symmetry breaking, the potential also includes the {\phi}3term. The consequent
field equation is a fourth-order differential equation and is considered to
have solitary solutions. The sech method is applied and the normalized
solutions are obtained in closed forms and the energy spectrum of the solitary
fields is determined. The modification parameter of the theory is estimated by
the width and the energy of the obtained solitary fields.
