    摘要: A highly reliable display apparatus is provided. The display apparatus includes a first light-emitting device, a second light-emitting device, and an inorganic insulating layer. The first light-emitting device includes a first pixel electrode, a first light-emitting layer over the first pixel electrode, and a common electrode over the first light-emitting layer. The second light-emitting device includes a second pixel electrode, a second light-emitting layer over the second pixel electrode, and the common electrode over the second light-emitting layer. The inorganic insulating layer covers side surfaces of the first pixel electrode, the second pixel electrode, the first light-emitting layer, and the second light-emitting layer. The hydrogen concentration and the carbon concentration in the inorganic insulating layer are each preferably sufficiently low.

    摘要: Secondary batteries using lithium cobalt oxide as positive electrode active materials have a problem of a decrease in battery capacity due to repeated charging/discharging, for example. A positive electrode active material particle which hardly deteriorates is provided. In a first step, a container in which a lithium oxide and a fluoride are set is placed in a heating furnace, and in a second step, the inside of the heating furnace is heated in an atmosphere containing oxygen. The heating temperature of the second step is from 750° C. to 950° C., inclusive. By the manufacturing method, fluorine can be contained in the positive electrode active material particle to increase the wettability of the surface of the positive electrode active material so that the surface of the positive electrode active material is homogenized and planarized. The crystal structure of the thus manufactured positive electrode active material is unlikely to be broken in repeated high-voltage charging/discharging. Thus, secondary batteries using the positive electrode active material having such a feature have greatly improved cycle characteristics.

    摘要: A semiconductor device having a large on-state current and high reliability is provided. The semiconductor device includes a first insulator, a first oxide over the first insulator, a second oxide over the first oxide, a third oxide and a fourth oxide over the second oxide, a first conductor over the third oxide, a second conductor over the fourth oxide, a fifth oxide over the second oxide, a second insulator over the fifth oxide, and a third conductor over the second insulator. The fifth oxide is in contact with a top surface of the second oxide, a side surface of the first conductor, a side surface of the second conductor, a side surface of the third oxide, and a side surface of the fourth oxide. The second oxide contains In, an element M, and Zn. The first oxide and the fifth oxide each contain at least one of constituent elements included in the second oxide. The third oxide and the fourth oxide each contain the element M. The third oxide and the fourth oxide include a region where the concentration of the element M is higher than that in the second oxide.

    摘要: A novel sputtering target is provided. The sputtering target includes a first region and a second region. The first region contains a first metal oxide containing an element M1 (the element M1 is one or more elements selected from Al, Ga, Si, Mg, Zr, and B). The second region contains a second metal oxide containing indium and zinc. The first region and the second region are separated from each other. Each of the first region and the second region is a crystal grain. A crystal grain boundary is observed between the first region and the second region. The diameter of each of the first region and the second region is greater than or equal to 5 nm and less than or equal to 10 μm.
