Metal Organic Chemical Vapor Deposition (MOCVD) is a semiconductor epitaxy process used to grow high-quality thin films and III-V compound semiconductor structures for photonics, optoelectronics, solar cells, laser diodes, LEDs, and advanced microelectronic device fabrication.
Metal Organic Chemical Vapor Deposition (MOCVD) is widely used to fabricate custom III-V semiconductor epi structures for photonics, optoelectronics, infrared detectors, laser diodes, LEDs, and advanced microelectronic devices. Researchers often use MOCVD to grow precise InGaAs, InP, GaAs, AlGaAs, and related compound semiconductor layers with controlled thickness, doping, and composition.
A PhD researcher in physics requested a custom InGaAs PIN epi wafer structure grown on an InP substrate:
I would like to ask if your company has PIN InGaAs epi wafers, or if your company can customize PIN InGaAs epi wafers.
The possible structure is as follows:
The dopant and doping concentration are not the main concern for this application.
UniversityWafer, Inc. replied:
We can help produce a variety of custom epi structures on III-V semiconductor substrates using MOCVD. In general, the customer provides the required layer design, and the epi structure is fabricated according to the requested specifications.
The example InGaAs/InP structure can be produced. For this type of wafer, the InP substrate would typically be 2" diameter × 350 µm thick rather than 100 µm. Researchers may specify whether the substrate should be n-type, p-type, or semi-insulating depending on the final device design.
A 0.1 µm InP cap layer may be suitable depending on the intended device application, surface protection requirements, and electrical structure. Custom MOCVD epi wafers can be designed for photodiodes, PIN detectors, laser structures, optical sensors, and compound semiconductor research.
