Abstract
PURPOSE:To prevent the generation of damages in the parts of moisture sensitive films and substrate, etc., at the time of dividing the substrate by forming silicon nitride films having the weak adhesion to a hydrophobic org. material to be formed as the moisture sensitive films at a required width to the parts of the dividing boundary lines on the substrate. CONSTITUTION:The silicon nitride film 3 is deposited to a required thickness on the substrate 1 and a mask is brought into tight contact with the surface thereof. The patterns of the prescribed width including the boundary lines 2 are formed on the substrate 1 when the silicon nitride film 3 except the patterns is removed by an RIE method and the mask is removed. The hydrophobic org. material is then stuck to element forming regions 5 and is subjected to heating and photoirradiation to induce crystallization and copolymn. reaction, by which the org. material is cured and the moisture sensitive films 6 are formed to the parts except the silicon nitride films 3. Blades of a dicer are pressed to the substrate along the boundary lines 2 from above the silicon nitride films 3 of the prescribed width, by which the substrate 1 is divided and the chips of moisture sensitive elements are formed.
