摘要:
A semiconductor heterostructure with reduced unintentional Calcium (Ca) impurity concentration of about 1 x 10 14 /cm 3 or less. A Calcium impurity reduction structure may comprise a single low temperature layer or a multilayer superlattice with alternating low temperature and high temperature layers, wherein the Calcium impurity reduction structure is sandwiched between high temperature layers. The semiconductor heterostructure is comprised of a III-nitride alloy.

摘要:
The yield of a manufacturing process of a display device is increased. The productivity of a display device is increased. A hydrogen-containing layer is formed over a substrate. Then, an oxygen-containing layer is formed over the hydrogen-containing layer. After that, a first layer is formed over the oxygen-containing layer with the use of a material containing a resin or a resin precursor. Subsequently, first heat treatment is performed on the first layer, so that a resin layer is formed. Next, a layer to be peeled is formed over the resin layer. The layer to be peeled and the substrate are separated from each other. The first heat treatment is performed in an oxygen-containing atmosphere.
