Buy a Silicon Wafer | Frequently Asked Wafer Questions

//
Comment0
Silicon wafers are an integral part of electronic components and solar energy systems. When it comes to wafers and the way they are made, there are certain things that are important to know. Let’s take a look at some questions we get asked a lot when it comes silicon wafers. And, as always, come see us when you are ready to buy a silicon wafer. How Do I Choose the Thickness of a Wafer? Wafer thickness is always determined by the automated strength of the materials used. That means that the wafer should be thick enough that it doesn’t crack during handling. What is a Silicon Wafer Used For? Silicon wafers have two primary uses. The first is the creation of a semiconductor. Silicon is the best and the most used semiconductor due to its extreme mobility both at high temperatures and at room temperature. This, along with the fact that electrical currents can pass through silicon easily, make it ideal for electronic devices. The second use is in the production of both chips and microchips in electronic gadgets. The semiconductors that utilize silicon wafers are widely used to create integrated circuits. Integrated circuits act as commands for specific actions in various electronic devices. Do You Need to Buy a Silicon Wafer?

InP Reclaim Wafers | Wafer Related Terms You Need to Know

Wafers are a key component in the majority of technological components. They are used in electronics for the fabrication of integrated circuits and in photovoltaics for conventional, wafer-based solar cells. While the majority of wafers are purchased brand new, in some situations reclaimed wafers can be used for a fraction of the cost. Let’s take a look at some terms you should know when it comes to InP reclaim wafers. Important Wafer Terms Boat – A boat is a device made of high purity temperature resistant materials. This can include fused silica, quartz, or poly Si. It is designed to hold many semiconductor wafers during thermal or other processes. A boat can also refer to a device that is designed to simultaneously contain source material during evaporation and heat the source to its melting point. Cleanroom – A clean room is a secure, and clean, space where the semiconductors are manufactured. Every aspect of a cleanroom is strictly controlled, from the room temperature to the number of particles in the air. Cleanrooms are rated and range from Class 1 to Class 10,000. The number corresponds to the number of particles per cubic foot. Reclaim Grade – Reclaim grade refers to the grade of a reclaim wafer. A reclaim wafer is a lower quality wafer that has been used in manufacturing and then reclaimed and used a second time in manufacturing. Are You Interested in InP Reclaim Wafers?

Wafer Manufacturing | 3 Key Steps of Wafer Fabrication

Do you own a piece of technological equipment? Then in a roundabout way, you own a wafer. Wafers are a key component in the operation of technological appliances from smartphones, to computers, and even cars. When it comes to the creation of wafers, it can be broken down into three main steps. Let’s take a look at the three key steps of wafer manufacturing. Deposition During this process, layers of different materials are introduced onto the wafer surface. There are several different ways this can be done. These layers are typically metals, insulators, or semiconductors. In some cases, a single layer is “deposited”. In other instances, multiple layers are deposited sequentially. Patterning Patterning takes place when a photosensitive layer is applied and then patterned by projecting a mask image onto the layer. The layer is then developed to create a pattern on the wafer. The development process is similar to the old development process of film and pictures. Pattern Transfer After the patterning is completed, the pattern on the wafer is then transferred to the layer, or layers, below. This done by a process called pattern transfer. The transfer process is typically executed by etching, although sometimes it can be done by deposition. The etchant minimally attacks the photosensitive material but attacks layers below strongly.
