    摘要: Methods of growing and manufacturing aluminum nitride crystal, and aluminum nitride crystal produced by the methods. Preventing sublimation of the starting substrate allows aluminum nitride crystal of excellent crystallinity to be grown at improved growth rates. The aluminum nitride crystal growth method includes the following steps. Initially, a laminar baseplate is prepared, furnished with a starting substrate having a major surface and a back side, a first layer formed on the back side, and a second layer formed on the first layer. Aluminum nitride crystal is then grown onto the major surface of the starting substrate by vapor deposition. The first layer is made of a substance that at the temperatures at which the aluminum nitride crystal is grown is less liable to sublimate than the starting substrate. The second layer is made of a substance whose thermal conductivity is higher than that of the first layer.

    摘要: A compound semiconductor single-crystal manufacturing device (1) is furnished with: a laser light source (6) making it possible to sublime a source material by directing a laser beam onto the material; a reaction vessel (2) having a laser entry window (5) through which the laser beam output from the laser light source (6) can be transmitted to introduce the beam into the vessel interior, and that is capable of retaining a starting substrate (3) where sublimed source material is recrystallized; and a heater (7) making it possible to heat the starting substrate (3). The laser beam is shone on, to heat and thereby sublime, the source material within the reaction vessel (2), and compound semiconductor single crystal is grown by recrystallizing the sublimed source material onto the starting substrate (3); afterwards the laser beam is employed to separate the compound semiconductor single crystal from the starting substrate (3).
