What is Wafer-Level Packaging?

Wafer-level packaging (WLP) is the technology of packaging the die while it is still on the wafer—protective layers and electrical connections are added to the substrate before dicing. Originally, wafers were diced into individual chips, then packaged. Utilizing WLP technology allows chips to continue to reduce in size, streamline manufacturing, and provide easier ways to test chip functionality.

The Need for Temporary Bonding and Ultrathin Wafers

To create new stacked designs, manufacturers must find ways to thin their device wafers before performing complex back-end processes. Using temporary bonding techniques in which the wafer is attached to a stable carrier without disrupting back-end processes can overcome this problem.

Benefits of Ultrathin Wafers

More than Moore

Moore’s Law originally stated that the number of transistors would double every two years. However, the timeline has increased to 18 months. Moore’s Law has proven useful in the semiconductor industry as a way for companies to guide long-term planning and set targets in research and development.

Since physical limitations to transistor scaling is being reached, moving beyond Moore’s Law has become a necessity. More-than-Moore Technology (MtM) focuses on creating new technological possibilities with unlimited application potential through research and development past already conventional methods.

Benefits of MtM

  • Quicker time to market
  • Lower cost
  • Improved performance
  • Reduced size and space
  • More flexibility
