| 20150368118 | Heat Insulating Material - A heat insulating material includes a porous sintered body formed of MgAl | 12-24-2015 |
| 20160118254 | OXIDE AND METHOD FOR FORMING THE SAME - An oxide that can be used for a semiconductor in a transistor or the like is formed. After a sputtering gas is supplied to a deposition chamber, a plasma including ions of the sputtering gas in the vicinity of a target. The ion of the sputtering gas is accelerated and collides with a target, so that flat-plate particles and atoms included in the target are separated from the target. Surfaces of the plurality of flat-plate particles are negatively charged in plasma. One of the flat-plate particles negatively charged is deposited with a surface facing a substrate. Another flat-plate particle is deposited in a region apart from the one flat-plate particle over the substrate while repelling the one flat-plate particle. An atom and an aggregate of atoms are inserted in a gap between the one flat-plate particle and the another flat-plate particle and grow in the lateral direction in the gap between the flat-plate particles, so that the gap between the one flat-plate particle and the another flat-plate particle is filled. | 04-28-2016 |
