    • Methods for the sustained, high-volume production of Group III-V compound semiconductor material suitable for fabrication of optic and electronic components, for use as substrates for epitaxial deposition, or for wafers. The equipment and methods are optimized for producing Group III-N (nitrogen) compound semiconductor wafers and specifically for producing GaN wafers. The method includes reacting an amount of a gaseous Group III precursor as one reactant with an amount of a gaseous Group V component as another reactant in a reaction chamber to form the semiconductor material; removing exhaust gases including unreacted Group III precursor, unreacted Group V component and reaction byproducts; and heating the exhaust gases to a temperature sufficient to reduce condensation thereof and enhance manufacture of the semiconductor material. Advantageously, the exhaust gases are heated to sufficiently avoid condensation to facilitate sustained high volume manufacture of the semiconductor material.
    • 用于持续,大批量生产适用于制造光学和电子部件的III-V族化合物半导体材料,用作外延沉积的基底或用于晶片的方法。 该设备和方法被优化用于生产III-N(氮)化合物半导体晶片,并专门用于生产GaN晶片。 该方法包括将一定量的作为一种反应物的气态III族前体与一定量的气态V族组分作为反应室中的另一反应物反应以形成半导体材料; 去除废气,包括未反应的III族前体,未反应的V族组分和反应副产物; 并将废气加热到足以减少其冷凝的温度,并且增强半导体材料的制造。 有利地,排气被加热以充分避免冷凝,以促进半导体材料的持续高容量制造。
