Abstract

ABSTRACTThe structure of (111) oriented, unheated oxygen-implanted silicon (dose -7.3×1016cm-2) has been studied by transmission electron microscopy (TEM). The as-implanted material exhibited four structurally different layers: defect-free monocrystaline silicon, amorphous silicon, monocrystalline silicon with a high defect density, and the perfect crystalline substrate. After heat-pulse annealing for 20s at 800°C, 900°C, or 1000°C, the amorphous layer recrystallized resulting in polycrystalline silicon, rich in oxygen. The uniform insulator buried layer was not formed under these specific implantation and annealing conditions.
