Latest Patents

One of Kishimoto's latest patents is a DNA analysis apparatus. This invention allows for accurate and sensitive sequencing in pyrosequencing by enabling the complementary strand synthesis reaction to proceed homogeneously and completely in a short time. The DNA, which serves as the sequencing target, is immobilized on the surface of a solid support. Nucleic acid substrates are injected from a dispenser to the support site, where complementary strand synthesis is performed rapidly and completely under a small reaction volume. Following this, the support, along with the product, is moved into a luminescence reaction solution, allowing for a distinct separation of the DNA complementary strand synthesis reaction site and the luminescence reaction site. The support surface is also washed by dipping it in the luminescence reaction solution containing a luminescence reagent and an enzyme that degrades redundant nucleic acid substrates.

Another notable patent is a mask for exposing a wafer with radiation and its exposition method. This invention features a radiation exposure mask equipped with at least two radiation exposure windows. Each window includes a mask pattern of a smaller pattern area, which is derived by dividing a pattern area that constitutes an integrating circuit chip into multiple areas. The semiconductor wafer is exposed to radiation while the radiation exposure mask is intermittently moved by a distance equal to the size of the small pattern area.
