Semiconductor device with gainas substrate and algaas laser diode
A recently granted patent (Publication Number: US12002859B2) discloses a semiconductor device featuring a monocrystalline substrate made of gallium indium arsenide solid solution with specific indium content percentages. The substrate is manufactured using the vertical gradient freeze (VGF) method for crystal growing and supports aluminum gallium arsenide-based semiconductor components, particularly laser diodes. The substrate's crystal orientation, doping elements, and lattice parameters are carefully controlled to ensure optimal performance and stress management within the semiconductor device.
Furthermore, the patent claims detail various aspects of the semiconductor device, including the specific indium content range of the substrate, crystal orientations, doping concentrations, and the absence of stress-compensating layers or phosphorus additions during growth. The semiconductor layer sequence of the components is designed to maintain overall stress balance or induce predetermined mechanical stress for enhanced functionality. Additionally, the patent mentions the possibility of stacking multiple semiconductor components within the device. Overall, the patented semiconductor device showcases a sophisticated design aimed at maximizing performance and reliability in laser diode applications through precise control of material properties and structural configurations.
