<p>Strewing apparatus (1) for even distribution of small hard particles of semi-conducting material. The strewing apparatus (1) comprises an upper charge plate (2) and a lower charge plate (3), the upper charge plate (2) having an inlet opening (20) for the introduction of the particles while the lower charge plate (3) have an outlet gap (30) for ejection of the particles. A distance DII between the upper charge plate (2) and the lower charge plate (3) at a position where the outlet gap (30) is arranged is larger than a distance DI between the lower charge plate (3) and the upper charge plate (2) where the inlet opening (20) is arranged. There is a voltage potential between the upper charge plate (2) and the lower charge plate (3).</p> |
