A silicon wafer fabrication service that a thin film company provides usually includes an array of services to its clients; in other words, a one-stop-shop for those that need wafer production service. This provides an advantage to many companies that use wafers as a raw material for manufacturing as this help them to reduce the production costs. But what are these so-called 'array of services'? Below are some examples of services you can get from a wafer fabrication service provider:
Lithography - people in the semiconductor industry also called it as "photolithography"; it is used to draw patterns on the surface of a wafer or substrate. The procedure is done through the help of a light sensitive polymer called photoresist. These days, lithography services usually include engineering support for mask layout and the process development. There is also called advanced lithography process.
Wet etching - this is a process is utilized to chemically remove layers from a substrate's surface; it is considered to be one of the most important parts of the whole process as wafer undergoes a number of etching before completing the whole procedure. Today, as equipment are getting more and more sophisticated, companies are able to provide etching capabilities that handle wafers in smaller quantities; they are able to etch even 300mm and smaller diameters, and more a wide variety of dielectrics and metal films.
Kiss polishing - this system is performed to transform old and well-used wafers into a brand new one (and of course so that they can be used like a brand new one again). The service includes several steps, which include visual inspection to evaluate and separate right away those wafers with chips and cracks (they are returned to owner unprocessed). Kiss polishing (along with other wafer reclaim and recovery processes) helps prolong the life of the wafers, providing manufacturers an advantage particularly when it comes to operational costs.
The continuous development of the wafer fabrication business as well as foundry service providers and the semiconductor industry as a whole contributes to achieving even brighter future for many industries particularly those businesses that are in the electronic sectors. Better quality substrates used in various electronic device productions are a key component in manufacturing better products, which will certainly fuel industry growth.
