Top 10 OSAT Companies in World
 
As new technologies such as three-dimensional (3D) stacking of integrated circuits and others are introduced, the complexity of chip-package interaction is going up significantly and it is increasingly difficult for foundries to deliver end-to-end solutions that meet the requirements of the broad range of leading-edge designs. 
 
To deal with this situation a ‘subcontract’ assembly method is employed known as OSAT. OSAT provides third-party IC-packaging and test services. The OSATs are merchant vendors of IDMs and foundries who have internal packaging operations which can be outsourced to a certain percentage of their IC-packaging production to the OSATs. The fabless companies also taking the same route and outsource their packaging to the OSATs and/or foundries.
 
OSAT helps to meet overflow capacity when upside demand could not be met through internal manufacturing, OSAT enables the supply chain to better meet diverse requirements and deliver robust and reliable solutions to common customers. Semiconductor companies cut their packaging prices by 2% to 5% every year by outsourcing to OSATs. 
 
With the convergence of voice, video and data functions into a single platform, semiconductor manufacturers are relying on OSAT companies to boost their ability to achieve these new levels of functionality by pushing integration technology to new levels. 
 
According to Gartner, the combined IC-packaging and test service market, which includes OSATs, foundries, and IDMs, is projected to reach $53.3 billion in 2017. Yole Development forecasts, in 2019, the IC packaging market, which includes all technologies, is projected to reach $68 billion in terms of revenues, up 3.5% over 2018.
 
Obviously, the forecasts could change year on year amid uncertainty in the economic climate. What hasn’t changed is that the OSAT market is a tough and competitive business with lower margins. Customers.
