Fabricate Low Temperature BEOL Schottky Contact Diodes
A PhD student a PhD student requested the following quote:
We need Si wafers with a layer of n type doped amorphous Silicon on top (1e18- 1e19). Do you have or do you offer any wafers matching this description?
We are planning to make low temperature BEOL compatible schottky contact diodes out of the low temperature Si (a-Si) doped Si. Our previous work demonstrated this with phosphorous doped c-Si and poly-Si (600 C deposited Si). We now plan to see if it works for low temperature (below 400 C) a-Si for BEOL compatibility.
The ideal stacks of films (from bottom to top) we are looking for are as follows:
- 4" Si wafer; P type; 100 crystal orientation; 1-20 ohm-cm resistivity; SSP; Test grade
- Thermal Oxide of 1000 A on both sides of the wafer
- Low temperature Si (Amorphous Si) of thickness in between 1000-2000 A and with n-type doping of different doping concentration of around 1e+18 and 1e+19 /cm3 on the top of the wafer.

What is Crystalline Silicon (C-Si)?
C-Si is a silicon cell. It is an excellent alternative to conventional solar cells. It is also highly efficient, but costs a little more. In order to make a good solar panel, it should be sized properly and should be efficient. Several factors affect the efficiency of a solar cell. The first factor is the size of the panel. The larger the panel, the more energy it can produce. A smaller panel can be more expensive than a larger one, but can be more efficient.
Monocrystalline silicon is the most common form of PV materials, and it has many advantages over its 
amorphous counterpart. Its light weight and easy fabrication make it a very useful material for solar panels. In addition, it is amenable to improvements in capex processes. As a result, its efficiency is increasing all the time. This makes it an excellent material for rooftop solar panels, and it is also the most expensive.
There are two types of silicon: a-Si and c-Si. While monocrystalline silicon has more efficiency than a-Si, both are used in photovoltaic technology. In photovoltaic systems, crystalline silicon is used to create solar cells. Solar panels are assembled into solar panels. There are several advantages of both types of materials. If you are wondering which one is right for your project, keep reading! You'll soon find out!
Despite the similarities in structure, both crystalline and allotropic silicon have their own distinct benefits. They are both light weight, easy to fabricate, and amenable to capex processes. They also both have high efficiencies that make them reliable and cost-effective. The applications for both materials continue to grow. If you are wondering, "What is c-Si? ", you've come to the right place.
A-Si is the oldest thin-film technology. This technology involves chemical vapor deposition (CVD) to place a thin layer of silicon on a substrate. This type of silicon absorbs a wide range of light and performs well even in low light, but a-Si is not as efficient as c-Si, and it isn't recommended for portable solar applications.
Another type of c-Si is microcrystalline silicon, or nanocrystalline silicon. Both are types of amorphous silicon, with small crystalline-silicon grains separated by grain boundaries. Although c-Si is the most common type of semiconductor, nano-Si is the more common type. Its name comes from the fact that it is a fine-grained form of polysilicon.
Nanocrystalline silicon is a form of silicon. It is allotropic, and it is the most common type of amorphous silicon. In contrast, polycrystalline silicon contains tiny crystalline-silicon grains that are separated by grain boundaries. It is best used for applications that require fine-grained components. However, this type of silicon is a good choice for applications that require a narrow grain-size.
Another type of silicon is called nanocrystalline. This type is amorphous and is not crystalline. It is amorphous, but is also the most popular type of silicon. It is amorphous, and is formed in the same way as amorphous silicon. It is amorphous, which means that it is an amorphous form of silicon. While it is not a crystalline material, it is amorphous.
The amorphous phase of silicon is amorphous. The amorphous phase is the most common type. It has no grain boundaries, but contains many crystalline-silicate particles. Amorphous silicon is amorphous, and its grains are separated by grain boundaries. This is why it is often used in electronics. Its properties are similar to crystalline silicon, but can be made up of nanocrystalline layers.
CIS solar cells can be combined in tandem solar cells. The difference between them is that the former has better stability and resistance to shading. The latter is more efficient than amorphous silicon, and is therefore a good alternative for residential and commercial solar applications. The amorphous and protocrystalline silicon solar cell are best for short-wavelength light. Long-wavelength light is absorbed by the amorphous silicon substrate.
Amorphous silicon is made of amorphous silicon and contains large, irregular silicon grains. Amorphous silicon is the most common type of crystalline-si solar cells, but there are other types of the material as well. It is also used in thin-film solar cells. As a result, these solar cells are less efficient than their amorphous counterparts. It is difficult to control the amorphous form, and thin-film modules require more surface area.
