In an ion implantation method, a substrate is placed in a process zone and ions are implanted into a region of the substrate to form an ion implanted region. A porous capping layer is deposited on the ion implanted region. The substrate is annealed to volatize at least 80% of the porous capping layer overlying the ion implanted region during the annealing process. An intermediate product comprises a substrate, a plurality of ion implantation regions on the substrate, and a porous capping layer covering the ion implantation regions. |
