发明名称 マイクロピット密度(MPD)が低いゲルマニウムのインゴットを製造する方法、およびゲルマニウム結晶を成長させる装置
摘要 <p>Systems and methods are disclosed for crystal growth including features of reducing micropit cavity density in grown germanium crystals. In one exemplary implementation, there is provided a method of inserting an ampoule with raw material into a furnace having a heating source, growing a crystal using a vertical growth process wherein movement of a crystallizing temperature gradient relative to the raw material/crucible is achieved to melt the raw material, and growing, at a predetermined crystal growth length, the material to achieve a monocrystalline crystal, wherein monocrystalline ingots having reduced micro-pit densities are reproducibly provided.</p>
