Semiconductors are big assets for different domains, so it is beneficial to learn about the products that function similarly to semiconductors for various devices and the giant companies that specialize in producing semiconductors. These are made from a fine substance called silicon. An extensive process is what manufactures extremely useful semiconductors. These include oxidation, metallic wiring, and many other crucial steps.
In this post, we will explore the production process of semiconductors with all the essential steps in detail for better understanding.
Steps in the Manufacturing Semiconductor Industry
1. Silicon Substrate Semiconducting Properties
The initial step in producing semiconductors is to position them on each other to form a stack. It is a complex symmetry and a complicated structure. The main factor that makes the semiconductors strong and efficient is the silicon wafer chip. It is the foundation that makes the semiconductors serve long through their performance. This silicon which is useful for semiconductors is obtainable directly from the sand. Below is the detail of the process that extracts silicon from sand for the production of semiconductors.
- Collect a considerable amount of sand from melting, and then turn this sand into small or big crystals.
- This forms the ingots of silicon which are broad and heavy. Cut these ingots into fine wafer surfaces of silicon which are fragile and slim to appear.
- The upper layer of these ingots is not only uneven but also needs proper refining so that the circuitry that includes the semiconductor performs well on all counts.
- These wafers have a special line-based design on the upper layer.
The average size of the silicon wafer processing determines the number of semiconductors. Small wafers cannot produce semiconductors in bulk.
2. Oxidation
The silicon wafer produced recently does not contain the conductive ability. There is another process that makes these wafers conductive. It is a crucial step, and the slightest negligence in this step can ruin the ability of wafers. The process of oxidation is important for silicon wafers. Spray the oxygen in the form of vapors on these wafers, which creates a fine coating on these wafers. Now, this layer acts as a protective layer from water leakages and protects the circuits from sparks as well. Due to this fact, it is important to execute the process of oxidation on the wafers with complete vigilance and care to not compromise their functioning while on the circuit boards.
3. Photolithography
The step of photolithography refers to producing a design of the circuit with the help of water. It is identical to the process of capturing a photo from a camera. It includes a photo mask which is an important factor in the process of photolithography. There is a special computer that produces the design of the circuit in an efficient way. The photoresist is a material that actually produces circuit design on water. It gets applicable equally on the oxide layer present on the wafer when this substance comes into contact with the light. The light penetrates the photo mask.
4. Etchin – Remove Unnecessary Materials
Etching means cleaning the wafer from unwanted residue and remains of the process so far. It helps in excluding the residue from the water layer just produced in the previous step. It ensures that only patterns are with the wafers. A special method of gas or liquid etching is useful to remove substances from the layers. There is a difference between both types of etching which is why it is important to consider both techniques before beginning to implement one of them.
- Wet Etching: It includes effective chemical substances only.
- Dry Etching: It includes plasma or gas in some cases for the process.
Suppose there is a stack of semiconductors that is smaller than the width of a common paper. Both the steps of etching and photolithography are frequently executable on each layer present in this stack. There is also a fine insulator which is in the form of a film, that divides these layers to provide feasibility during these processes. It also protects the stack as well. The entire process is also identical to the production process of Multilayer printed circuit boards.
5. Deposition & Implementation of Ion
The deposition is the process that delivers a thin atomic layer on the wafer. There are several benefits to attaching this layer to the previous layers already present on a particular wafer. It is a feasible method and does not take much time as well, and It accurately attaches the deposition layer to the wafer. It is the main layer that provides the semiconductors with different electrical as well as conductive attributes. The process also includes a sub-step of ion implementation. A semiconductor also has some impurities due to the extensive process of manufacturing. All the abovementioned steps are important to give electrical and conductive attributes to these wafers so that they can work with several other circuits without any complications.
6. Metal Wiring
Metallic wiring is important to make this entire set-up work which is why this should be done with utmost precision by the responsible technicians. This step conducts the electrical signals throughout the entire circuit. A clear and uninterrupted path is needed for the smooth current flow of the circuit. A thin layer of metals like titanium, tungsten, or others is also useful to conduct electricity in a flawless manner regarding the performance of the semiconductor in the future.
7. EDS – Energy Dispersive Spectroscopy
The step is energy dispersive spectroscopy. This is a crucial step since it develops effective chip manufacturing of semiconductors. It can also be useful to eliminate faulty microchips that can create complications in the future while performing. The unit of yield is for measuring the relativity of prime chips as compared to one wafer on the basis of MCC or maximum chip count. This testing step is important to shortlist the best pieces for assembling into the circuit boards.
8. Packaging in the semiconductor manufacturing process
Packaging is the step that winds up the production process. The whole structure of the previously produced wafers is divided into small chips that can be easily attached to an electronic device that functions with the help of a semiconductor. The chips that have been securely cut are then positioned on the printed circuit boards. The sub-step of bonding combines both the contact points of these chips and the substrates. Then another sub-step of molding gives these chips a proper shape that fits with the circuit boards. Then sealing and naming of these chips is important to differentiate them from others that have been produced. This mainly helps in shipping and delivering the semiconductors to the suppliers and direct clients.
