METHOD OF TRANSFORMING SLICE OF POLYCRYSTAL SEMICONDUCTOR INTO SLICE OF HUGE CRYSTAL SEMICONDUCTOR |
摘要 |
Polycrystalline semiconductor strips are transformed into single crystals by producing by a laser beam a fusion zone in a region which is narrow compared with the strip width. A part of this zone is solidified to a crystal and as the fusion zone is extended along the strip, the single crystal also expands. Process is reliable and economical and no seed crystal is needed. |
