Abstract: Let $H$ be a Hilbert space with the inner product $$ and the norm $|cdot|$, $A(t)$ a positive self-adjoint unbounded time-dependent operator on $H$ and $varepsilon > 0$. We establish stability estimates of H"older type and propose a regularization method with error estimates of H"older type for the ill-posed backward semi-linear parabolic equation
$$
begin{cases} u_t(t)+ A(t)u(t)=f(t,u(t)), quad 0 < tleqslant T,
|u(T)-varphi|leqslantvarepsilon,
end{cases}
$$
with the source function $f$ satisfying a local Lipschitz condition.
