  • Patent number: 11983583
    Abstract: In a method of manufacturing a multilayer chip component according to an aspect of the present disclosure, laser processing is used for forming dots of a two-dimensional code. This laser processing is laser processing with respect to a laminate substrate in a state before baking is performed, and an impact at the time of processing is absorbed to a certain degree due to elastic deformation of the laminate substrate. For this reason, according to the manufacturing method, occurrence of cracking can be curbed compared to laser processing with respect to an element body in a state after baking is performed.
    Type: Grant
    Filed: April 4, 2023
    Date of Patent: May 14, 2024
    Assignee: TDK CORPORATION

  • Patent number: 11568192
    Abstract: In a multilayer chip component according to an aspect of the present disclosure, dots of a two-dimensional code provided on a main surface of an element body has a semicircular cross-sectional shape. That is, since substantially no corner portions are present in a cross-sectional shape of the dots, stress is unlikely to remain when the dots are formed, and stress is unlikely to be concentrated after the dots are formed. Therefore, cracking is unlikely to occur in the foregoing multilayer chip component.

  • Publication number: 20210248435
    Abstract: In a method of manufacturing a multilayer chip component according to an aspect of the present disclosure, a two-dimensional code is formed in each of green chips divided in a dividing step. In the two-dimensional code, a substrate ID identifying a laminate substrate and an individual body ID identifying an individual multilayer chip component are associated with each other. Therefore, it is possible to accurately and quickly discern which laminate substrate a multilayer chip component is manufactured from by reading the two-dimensional code of the multilayer chip component, and thus high traceability can be achieved.
