A PhD in Physics requested help with the following:
I would like to ask if your company has PIN InGaAs EPI wafers? Or could your company customize PIN InGaAs EPI wafers.
The possible structure is as following:
1: n+ InP substrate(100) 100um
2: n+ InP buffer 1um
3: n- In0.53Ga0.47As 3-4um
4: n- InP cap
The dopant and doping concentration is not our consideration.
UniversityWafer, Inc. Replied
We have a facility that can produce any of a variety of Epi structures on III-V semiconductor substrates by MOCVD. In general, we let the customer design the structure, and we produce what is specified
We can certainly produce the structure that you gave as an example.
The InP substrate would be 2"Ø×350µm {not 100µm}. Should the substrate be n-type or p-type or Semi-Insulating?
A cap layer 0.1µm thick, would that be adequate?

Metal Organic Chemical Vapor Deposition (MOCVD) is a mechanism of film deposition using chemical vapor deposition CVD is a coating process mainly used for thermal induced reactions at the surface of the heated substrate when seagent is used in their Mechanism in the following manner.
The deposition of highly uniform and their conducting thin film in the microelectronic are present on the miniaturization of semiconductor devices induced .D structure with a very high ratio.
Then forming silver films with the highest electrical conductivity and loest critical thickness are currently produced an lli surface of deposition surface.
Then we will use ultra-thin continuous silver oxide.
Finally follow the deposition of volmer weber growth.
These are a lot of advantages of Metal Organic chemical vapor deposition are:
Disadvantages of Metal Organic Chemical Vapor deposition are:
MOCVD is a coating process that uses metal ions to create thin film oxides. It can be used to create lead-based ferroelectric layers. The advantages of this process include achieving a uniform, high-conductivity thin film. The deposition source is a complex metal organic ligand. In addition, MOCVD allows for extremely low-cost production of lead-based ferroelectric layers.
The process involves the vaporization of solid or liquid precursors. In the past, lead alkyls were used as precursors, but these are toxic. Modern MOCVD processes use a more liquid-like approach, which allows for better control of doping and uniformity. In addition, the reaction process is simple and straightforward, so different layers can be formed at the same time. Despite these advantages, MOCVD has some limitations.
For example, the liquid precursors, called alkyls, are more environmentally friendly than the solid precursors. They are less hazardous than lead, and the resulting films are odorless and amorphous. Moreover, MOCVD processes can be continuous, meaning that no refilling is required during a deposition run. As a result, the process can be used to grow superconductor films.
In addition to producing highly conformal film layers, MOCVD offers superior thermal and electrical properties. In fact, MOCVD can also be used to create high-purity, high-power, and high-speed electronic devices. Besides, it's easier to manage the film stoichiometry with this process. The major disadvantage of MOCVD is its complexity in implementation. You need to have a proper lab and be sure you know what you're doing.
The advantages of MOCVD are numerous. The process can grow high-quality materials and can be designed easily. The Department of Electrical Engineering at Northern Illinois University has a MOCVD system that can handle six reactants at once. Its versatility allows it to fabricate various types of devices with multiple materials. In addition, MOCVD can be used to make solar panels, transistors, and other electronic devices.
The primary advantage of MOCVD is that it can grow high-quality materials, which are easy to handle. It can also be designed easily and affordably. For example, a system developed at the Department of Electrical Engineering of Northern Illinois University can handle up to six reactants at once. This system can be used to fabricate a variety of different device structures and materials. Research and development are underway to create solar cell devices using both zinc sulphide and selenitic materials.
While MOCVD is an efficient way to manufacture solar cells, it can also be difficult to produce materials with higher-quality features. However, MOCVD is a good solution for semiconductor applications. Its advantages include increased productivity and cost-efficiency. Further, MOCVD is ideal for high-volume production of bandgap-engineered heterostructures. Aside from its versatility, MOCVD is also highly customizable.
Rapid Thermal MOCVD is an attractive technology in the microelectronics industry. It can be used to deposit high-quality semiconductor films in short periods of time. The technique is also suitable for a variety of other applications. It is a highly-efficient method for a wide range of applications. You can achieve high-quality thin films by using this method. The advantages of this method are as follows:
The method is highly flexible. It is more flexible than other processes, allowing you to use more components in one step. In addition to its high-precision manufacturing, it is faster. The most recent study showed that the technique is capable of achieving higher-throughput, which means it is a significant advantage for semiconductor manufacturing. The high-precision process can help you produce more complex and intricate designs and improve the yield of semiconductors.
MOCVD has many advantages over other methods. In addition to high-precision manufacturing, MOCVD allows you to deposit thin films at high-volumes. Its large-scale production is advantageous, as it is more accurate than other methods. And, because it is a more flexible method, it is more economical than other processes. Aside from being cheaper, MOCVD can also create complex, multifunctional materials.
