What Is an Interposer?
An interposer is a substrate that plays a crucial role in electrically connecting sockets. Its primary function extends beyond mere connection; it facilitates the electrical integration of multiple semiconductor chips and substrates. This makes it an essential intermediary component, especially in situations where the pitch of the connections varies.
Interposers are constructed from a range of materials, including molded resin, silicon, glass, and organic polymers. The choice of material varies based on specific application needs. They are a popular alternative to three-dimensional integrated circuits due to their cost-effectiveness.
Utilizing interposers offers several advantages, such as reduced wiring length in implementations, simplification of circuits, and improved energy and resource efficiency.
