Epitaxy
Epitaxy is the process of growing a crystal of a particular orientation on top of another crystal such that both have the same structural orientation. The resulting structure is described as an epitaxial layer. In 1951 Gordon Teal and Howard Christensen at Bell Labs developed a process, now called epitaxial deposition, to grow a thin layer of material on a substrate that continues the underlying crystalline structure. Sheftal', Kokorish, and Krasilov described similar work on germanium and silicon in the U.S.S.R. in 1957. At the urging of Ian Ross, a Bell Labs team led by Henry Theurer used chemical-vapor deposition to add a thin epitaxial layer of silicon between the base and collector of a transistor in 1960. This approach raised the transistor's breakdown voltage while dramatically increasing its switching speed, (1961 Milestone) two important circuit-design characteristics. The added manufacturing cost of the extra process step was more than offset by improvements in device performance. The technology was quickly transferred to Western Electric and used in manufacturing silicon transistors for electronic telephone switching in the Bell System. Epitaxy

How six sigma developed?
Six Sigma is a manufacturing process control strategy which first implemented by Motorola. Six sigma being common used by any sectors of industry nowadays, especially those precision product manufacturing. Six Sigma manufacturing implemented to control the process or stabilize the process. Then, seeks to improve the quality of process outputs. Six sigma manufacturing tools are used to stablize or improve processes, aiming towards reaching the target.
What is the difference between Fabrication and Erection?
Fabrication: Manufacturing Process in which an item is made (fabricated) from raw or semi-finished materials instead of being assembled from ready-made components or parts. (Hindi meening: "Rachna"). Erection:Putting up (of a building etc.) upright in a position or posture.
What is the relationship between wafers and semiconductors?
Semiconductors of various designs are etched onto wafers of silicon. Those wafers are then tested to find out how many of the semiconductors have formed workable intergrated circuits. The wafer is then cut up into individual chips of intergrated circuits with the workable chips going further on in manufacuring and the non working chips either being dumped or pushed aside to lower speed chip manufacturing.
Are there materials other than just silicon that are being used to make semiconductor or other solid state electronic devices?
The other materials other than just silicon used to make semiconductors and other solid state electronic devices are germanium and gallium arsenide.
Why do you use the assembly line?
We use assembly lines because they help increase efficiency and productivity in manufacturing processes. Assembly lines allow for the division of labor and specialization, where workers can focus on specific tasks, leading to faster production and reduced costs. They also enable better quality control and consistency in the manufacturing process.
What is the formula 'SIO2' for?
The formula "SIO2" is commonly known as silicon dioxide. Silicon dioxide has a wide range of purposes, mainly being glass manufacturing. In nature, silicon dioxide is commonly found as sand and quartz.
How silicon carbide is manufactured?
Silicon carbide is typically manufactured using a process called Acheson method, where silica sand and carbon are heated in an electric resistance furnace at high temperatures. The reaction forms silicon carbide crystals, which can then be crushed and processed into various forms for different applications. The purity and quality of the final silicon carbide product depend on the control of temperature, atmosphere, and other process parameters during manufacturing.

What is standardized manufacturing?
Meaning everything is standardized, it's made to be more efficient by using the same process and tools to produce parts. You could think of it as being the opposite of customized manufacturing.. Hope this helps!
Which element has a similar behavior of silicon and lead?
Germanium is an element that exhibits similar behavior to silicon and lead. It shares some properties with silicon, such as being a semiconductor, and also shares some properties with lead, such as being a metalloid.
What is modular manufacturing?
Modular manufacturing is the process of constructing a pre-designed and customer approved modular building at the factory. While this process is being completed off site, the necessary site work is being completed on site. This results in a streamlined project that is complete in half the time of a conventional built building. For more information please visit modularsolutionsltd.com
Silicon is a metal?
Silicon is actually a metalloid, not a metal. It has properties of both metals and non-metals, such as being a semiconductor and having a crystalline structure.
What resources are being used to make laptops?

Is silicon elastic?
Silicon is generally considered to be inelastic, meaning it does not easily return to its original shape after being deformed. However, silicon can exhibit some elastic properties depending on its structure and how it is processed.
What is an example of a medical error in manufacturing?
Instances have been reported of blood products being mislabeled during the production process, resulting in patients being given transfusions of an incompatible blood type.
What is a silicon wafer?
Silicon wafers are a key component of integrated circuits such as those used to power computers, cellphones, and a wide variety of other devices. A silicon wafer consists of a thin slice of silicon which can be treated in various ways, depending on the type of electronics it is being used in. Silicon is a very high quality semiconductor, making it ideal for the production of such circuits, although other materials have been explored historically. Much of the world's production of silicon wafers was historically centered in the aptly-named Silicon Valley in California.If the development of the integrated circuit revolutionized human society, the silicon wafer deserves a big part of the credit. While other semiconductors were tested and tried, siliconproved to be the most stable and useful. Fortunately, the raw materials for silicon wafers are quite accessible, even if some work is required to produce wafer-grade silicon.Making silicon wafers is a lengthy process. A lab must grow a silicon crystal in highly controlled conditions to maintain purity, although the lab may selectively dope the crystal with certain ingredients during the growth process. Once the crystal is grown, it is cut into thin slices which must then be polished before they can used to make integrated circuits.
Does the earths crust have more silicon or oxygen in it?
The Earth's crust is primarily made up of oxygen (46.6%) and silicon (27.7%), with silicon being the second most abundant element in the crust.
