  • Publication number: 20200043860
    Abstract: A substrate stacking apparatus that stacks first and second substrates on each other, by forming a contact region where the first substrate held by a first holding section and the second substrate held by a second holding section contact each other, at one portion of the first and second substrates, and expanding the contact region from the one portion by releasing holding of the first substrate by the first holding section, wherein an amount of deformation occurring in a plurality of directions at least in the first substrate differs when the contact region expands, and the substrate stacking apparatus includes a restricting section that restricts misalignment between the first and second substrates caused by a difference in the amount of deformation. In the substrate stacking apparatus above, the restricting section may restrict the misalignment such that an amount of the misalignment is less than or equal to a prescribed value.

  • Patent number: 10424557
    Abstract: A substrate bonding apparatus that brings a part of a surface of a first substrate and a part of a surface of a second substrate into contact to form contact regions at the parts, and then enlarges the contact regions to bond the first substrate and the second substrate includes: a temperature adjusting unit that adjusts a temperature of at least one of the first substrate and the second substrate such that positional misalignment between the first substrate and the second substrate does not exceed a threshold at least in a course of enlargement of the contact regions.

  • Publication number: 20190267238
    Abstract: A method for bonding a first substrate and a second substrate includes: forming a protrusion at a partial region of the first substrate; measuring a position of the first substrate after the protrusion is formed in the first substrate; and bonding the first substrate and the second substrate by contacting the protrusion of the first substrate with a surface of the second substrate to form a contact region and enlarging the contact region.

  • Publication number: 20190148184
    Abstract: A method of manufacturing a stacked substrate by bonding a first substrate and a second substrate, including a step of determining, based on information about curving of each of the first substrate and the second substrate, whether or not the first substrate and the second substrate satisfy a predetermined condition, and, a step of bonding the first substrate and the second substrate if the predetermined condition is satisfied. The stacked substrate manufacturing method described above includes a step of estimating, based on the information, an amount of misalignment which occurs after the first substrate is bonded to the second substrate and the predetermined condition may include that the amount of misalignment is equal to or less than a threshold.

  • Publication number: 20190122915
    Abstract: A stacking apparatus that stacks a first substrate and a second substrate includes: a plurality of holding members that hold the first substrate, wherein the plurality of holding members correct positional misalignment of the first substrate relative to the second substrate by preset amounts of correction, and the plurality of holding members include holding members having the amounts of correction that are different from each other. The stacking apparatus may further include a carrying unit that carries a holding member that is selected from among the plurality of holding members and holds the first substrate from a position where the holding member is housed to a position where the first substrate is held.

  • Publication number: 20180308770
    Abstract: To improve the throughput of substrate bonding. A substrate bonding apparatus that bonds first and second substrates so that contact regions in which the first and second substrates contact are formed in parts of the first and second substrates and the contact regions enlarge from the parts, the apparatus including: a detecting unit detecting information about the contact regions; and a determining unit determining that the first and second substrates can be carried out based on the information detected at the detecting unit. In the substrate bonding apparatus, the information may be information, a value of which changes according to progress of enlargement of the contact regions, and the determining unit may determine that the first and second substrates can be carried out if the value becomes constant or if a rate of changes in the value becomes lower than a predetermined value.
