  We consider a family of semilinear parabolic problems with nonlinear boundary
conditions \[ \left\{ \begin{aligned} u_t(x,t) &=\Delta u(x,t) -au(x,t) +
f(u(x,t)),\ x \in \Omega_\epsilon \mbox{ and } t>0\,,\\
\displaystyle\frac{\partial u}{\partial N}(x,t) &=g(u(x,t)),\ x \in
\partial\Omega_\epsilon \mbox{ and } t>0\,, \end{aligned} \right. \] where
$\Omega_0 \subset \mathbb{R}^n$ is a smooth (at least $\mathcal{C}^2$) domain ,
$\Omega_{\epsilon} = h_{\epsilon}(\Omega_0)$ and $h_{\epsilon}$ is a family of
diffeomorphisms converging to the identity in the $\mathcal{C}^1$-norm.
Assuming suitable regularity and dissipative conditions for the nonlinearites,
we show that the problem is well posed for $\epsilon>0$ sufficiently small in a
suitable scale of fractional spaces, the associated semigroup has a global
attractor $\mathcal{A}_{\epsilon}$ and the family $\{\mathcal{A}_{\epsilon}\}$
is continuous at $\epsilon = 0$.
