摘要： A method for manufacturing a criss-cross type X-ray grid may include: forming a plurality of criss-cross type grooves at predetermined intervals in a longitudinal direction and a lateral direction in a substrate made of an X-ray transparent material, through a semiconductor sawing machine, such that the grooves form a checker board shape as a whole; putting the substrate having the criss-cross type grooves formed therein into a storage tank filled with a molten X-ray absorbent material; filing the criss-cross type grooves, formed in the substrate, with the X-ray absorbent material by vacuuming the inside of the storage tank; and taking the substrate filled with the X-ray absorbent material out of the storage tank, and curing the substrate at room temperature.
