A thin film company that offers silicon wafer fabrication service usually provides an array of services to clients i.e a one-stop shop for wafer production, which is advantageous to various companies in the industry particularly those that need wafers as a raw material for their manufacturing process. But what are these services? And why discussing this subject could be relevant to businesses in various industries? The following are some services that are part of silicon wafer fabrication:
Lithography - in semiconductor industry, it is called photolithography; this is a technique that put patterns on the surface of a substrate, where patterns are done using a light sensitive polymer called photoresist. Lithography services usually include engineering support for mask layout and, of course, 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 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 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.
