Abstract
A crystallization process comprising the steps of depositing a polycrystalline silicon layer on a semiconductor substrate, implanting silicon ions into first and second areas of the polycrystalline silicon layer in different amounts such that crystals having a predetermined plane direction remain in the second area and such that the first area becomes amorphous, and performing a thermal treatment to recrystallize the amorphous second area using the crystals having the predetermined plane direction remaining in the first area as a nucleus.
