    Abstract: To improve the yield in a peeling process and improve the yield in a manufacturing process of a flexible light-emitting device or the like, a peeling method includes a first step of forming a peeling layer over a first substrate, a second step of forming a layer to be peeled including a first layer in contact with the peeling layer over the peeling layer, a third step of curing a bonding layer in an overlapping manner with the peeling layer and the layer to be peeled, a fourth step of removing part of the first layer overlapping with the peeled layer and the bonding layer to form a peeling starting point, and a fifth step of separating the peeling layer and the layer to be peeled. The peeling starting point is preferably formed by laser light irradiation.

    Abstract: A method and an apparatus for manufacturing an object which involve a separation technique are provided. A first substrate provided with an object is attached to a second substrate and is then suction-fixed by using a suction chuck (also referred to as a suction stage or a vacuum chuck) including portions with different suction capabilities or by using its functional equivalent, and the second substrate is separated from the first substrate. Accordingly, the object is separated from the first substrate and transferred to the second substrate. An apparatus for achieving this is also provided. A substrate fixture surface of the suction chuck or its functional equivalent includes a plurality of portions provided with suction micro-holes and a portion provided with no holes. Owing to the plurality of portions provided with suction micro-holes, a plurality of objects can be transferred from the first substrate to the second substrate.

    Abstract: A highly reliable light-emitting device is provided. A yield in a manufacturing process of a light-emitting device is increased. A light-emitting device is provided in which a non-light-emitting portion having a frame-like shape outside a light-emitting portion includes a portion thinner than the light-emitting portion. A light-emitting element and a bonding layer are formed over a substrate. The light-emitting element is sealed by overlapping a pair of substrates and curing the bonding layer. Then, while the cured bonding layer is heated, pressure is applied to at least a portion of the non-light-emitting portion with a member having a projection.

    Abstract: An object is to predict a deterioration state of a secondary battery even in an environment where temperature and a charging voltage change. A lifetime estimation device of the secondary battery includes a measuring unit for measuring the capacity of the secondary battery in the full charging state; a temperature sensing unit for sensing the ambient temperature of the secondary battery; and a storage unit for storing a table of a proportional coefficient corresponding to temperature in advance, and a predicted deterioration line of the secondary battery is calculated with the use of a nonlinear regression equation approximated to a measured deterioration line obtained by the measuring unit. The lifetime estimation device may construct a lifetime estimation system with the use of a neural network.

    Abstract: A highly reliable flexible light-emitting device is provided. The light-emitting device includes a first flexible substrate, a second flexible substrate, a light-emitting element between the first flexible substrate and the second flexible substrate, a first bonding layer; and a second bonding layer in a frame shape surrounding the first bonding layer. The first bonding layer and the second bonding layer are between the second flexible substrate and the light-emitting element. The light-emitting element includes layer containing a light-emitting organic compound between the pair of electrodes. The second bonding layer has a higher gas barrier property than the first bonding layer.
