Silicon Wafer Fabrication - Some Services You Can Avail
A thin film company usually offers a one-stop-shop for those businesses that need wafer production service. This usually includes an array of services. Since these services come in package, getting these services provides an advantage to many companies that use wafer for their manufacturing process particularly in the issue of costs. But what are these services? (You might ask) I have listed below some specific services you can get from a wafer fabrication service provider:
Lithography - also known as photolithography, this process is used to put patterns on the face of the substrate, which is done through the use of a light sensitive polymer called photoresist. Today, lithography services usually include both engineering support for mask layout and the process development.
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 is utilized in the semiconductor industry to make well-used wafers look like brand new ones so that they can be used again. The process involves, first, the visual inspection so that wafers having chips and cracks are separated from those that don't have (wafers with such defects are returned unprocessed). This, along with other wafer reclaim and recovery processes, can extend the life of the wafers and therefore is advantageous particularly when it comes to costs.
The continuous improvement of the wafer fabrication system (as provided by foundry service providers) and the semiconductor industry as a whole play a key role 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 needed for the manufacture of much better products, which will certainly fuel industry growth.
