Latest Patents

Isaji's latest patents include a "Multi-Charged-Particle-Beam Writing Apparatus" and a "Multi-Charged-Particle-Beam Writing Method." In one embodiment of the writing method, a tracking operation is performed while a substrate on a continuously moving stage is irradiated with multiple charged particle beams. The deflection positions of these beams are adjusted to follow the stage's movement, ensuring that each rectangular region of the substrate is accurately irradiated. This method allows for precise control over the writing process, enhancing the quality of the output.

Another patent focuses on a "Method of Obtaining Beam Deflection Shape" and a "Method of Obtaining Arrangement Angle of Blanking Aperture Array Plate." This method involves using multiple beams to write a line pattern on a substrate, measuring the degree of unevenness at the edges of the pattern, and obtaining a deflection shape based on this measurement. These innovations are crucial for advancing the capabilities of charged-particle-beam technology.
