Microelectronics is a sub field of electronics and relates to the study and manufacture of very small electronic devices and components. These devices are typically made from semiconductor materials. Many components of  electronic design are available in a microelectronic equivalent. These include transistors, capacitors, inductors, resistors, , diodes and conductors can all be found in microelectronic devices.

Digital Integrated Circuit or IC consist of billions of transistors, resistors, diodes, and capacitors. These IC chip or die normally is attached onto lead frame or substrate using either conductive or non-conductive die attach adhesives.

To protect these IC chip or die as well as their interconnects (gold or aluminum wires), back-end IC packaging or assembly house would use liquid encapsulant or transfer molding technique to encapsulate their IC packages.
