At the linear collider, $e^+e^- \\to h^0A^0$ or $H^0A^0$ production processes may result in $b\\bar bt\\bar c$, $W^+W^-t\\bar c$ or $tt\\bar c\\bar c$ (or $\\bar t\\bar tcc$) final states. The process $\\gamma\\gamma \\to h^0,\\ A^0 \\to t\\bar c$ is also promising, but $e^+e^- \\to (h^0,\\ H^0) Z^0 \\to t\\bar c Z^0$ is relatively suppressed.
