Abstract:
PROBLEM TO BE SOLVED: To form the alignment layer which has its characteristics improved without any mechanical contact with a striking directional particle beam to impinge on a film surface and arranging at least one liquid crystal on the struck surface. SOLUTION: High-cost excessive layers and machining steps, and mechanical contact with the surface of the alignment layer are avoided by depositing the alignment layer directly on the surface with directivity. A substrate 10 is exposed to an ion beam 12 at a certain angle 14 of incidence. When the surface 16 is deposited with an ion beam 12, a material is deposited directly or indirectly on the surface 16 or is injected into the surface to form the alignment layer used to align light crystal. The layer can be made homogeneous by bonds preferentially aligned on the substrate surface 16 and the liquid crystal can be controlled more precisely. The thickness and electron characteristics of the alignment layer can be adapted such that optical performance can be obtained. Further, this alignment is manufactured economically in terms of time and cost. COPYRIGHT: (C)1999,JPO
Abstract:
PROBLEM TO BE SOLVED: To provide a method for forming an alignment layer on a substrate. SOLUTION: The film is adhered and aligned in a single step with a method containing a step to shoot an ion-beam at the substrate with a specified incident angle and simultaneously to adhere the film to the substrate (a) and to align an atomic structure of the film in at least a specified aligning direction (b).
Abstract:
PROBLEM TO BE SOLVED: To obtain a low-cost, reliable light crystal display which is manufactured in a small number of steps by depositing an amorphous alignment layer on a transparent substrate by using a dry machining method. SOLUTION: The amorphous alignment layer is deposited on the transparent substrate by using the dry machining method such as plasma-reinforced chemical vapor-phase deposition. Then the atomic structure of the dry-machined alignment layer is aligned to at least one desired direction by using a particle beam device 48. A plasma generation unit 52 operates to generate ions and a group of three electrodes 54, 56, and 58 takes ions out to irradiate the substrate 20. The substrate 20 is fixed to a plate fixation platform 62 so that an angle θ as an angle of incidence of accelerated particles to a line perpendicular to the substrate 20 is maintained. The angle θ is preferably in a range of about 20 to 80 deg.. The alignment layer may be formed by a nonaqueous gas environmental deposition method such as vapor deposition, sputter deposition, and ion beam deposition.
