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 - 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 - silicon wafer cleaning and etching is process that is used to chemically remove layers from the surface of the wafer (also known as substrate) during manufacturing; this is one of the most important parts of the process as wafer undergoes several etching process procedures before it is complete. Wet etching companies provide capabilities that allows the etching of 300mm and small diameters, for a wide array of dielectrics and metal films.
Kiss polishing - this is to process well-used wafers so that they appear like brand new ones again (and of course can be used like a brand new one again). This process involves a number of steps including visual inspection to check and separate the ones with chips and cracks; the wafers with defects are returned unprocessed. Kiss polishing helps extend the life of the wafers (along with other wafer reclaim and recovery processes) and thus it provides an advantage to businesses most especially when it comes to 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.
