Silicon wafer foundry service providers have been useful to the semiconductor industry and the sectors it serves. The advanced technology it offers, particularly with the advent of fabless business model, provides the affordability advantage, which is essential to maintaining minimal production costs of the their processes. Through foundry service providers' process capabilities, the production of semiconductor components such as MEMS have been efficient and cost-effective in the recent years.
A number of process capabilities have been serving clients in the semiconductor industry, including the following:
Lithography - also known as photolithography, it is a process that puts specific patterns on silicon wafers; the patterns are written on the substrates using a light sensitive polymer called photoresist. This process is essential to the production of semiconductor components that connect millions of transistors in a circuit.
Etching - in simpler terms, it is a process of making prints on the surface of the substrate or wafer. Several wafer foundry companies have a broad range of wet etching capability for 300mm and smaller diameters, for a broad range of dielectrics and metal films. They can also process non-standard sized substrates.
Wafer reclaim and recovery - the very purpose of this process is to extend the life of a wafer - for longer duration use. A wafer foundry company mechanically re-polishes wafers to remove surface scratches and residual patterns. While there is a certain limit on how many times a wafer can be reclaimed, still this process is considered a cost-effective solution for clients.
Thin films (dielectrics) - with this process capability, foundry companies use equipment like custom furnaces to facilitate processes like LPCVD and thermal oxide.
KISS Polishing - a process used by wafer foundry service companies to remove minor surface scratches or defect on the substrates. This service includes visual inspection of wafers for chips and cracks.
There are still a lot of process capabilities inside a silicon wafer foundry service facility - thanks to the people behind these innovations. True indeed that they are a big help to the semiconductor industry and the sectors it serves.
