Wafer Level Chip Scale Package refers to the technology of packaging an integrated circuit at the wafer level, instead of the traditional process of assembling individual units in packages after dicing them from a wafer. This process is basically an extension of the wafer Fab processes, where the device interconnects and protection are ...

Mar 17, 2018· IC design flow is not exactly a push button process. To succeed in the IC design flow process, one must have: a robust and siliconproven flow, a good understanding of the IC specifications and constraints, and an absolute domination over the required EDA tools (and their reports!). This article covers the IC design flow in very high level.

Wafer acceptance test (WAT) or commonly known as process control monitoring (PCM) data is the data that is collected at the last stage of wafer fabrication process. This data is taken directly from the various test structures placed on wafer's predefined test sites. Usually, a set of multiple test structures is positioned for every reticule.

Through a process called ion implantation (one form of a process called doping), the exposed areas of the silicon wafer are bombarded with various chemical impurities called Ions. Ions are implanted in the silicon wafer to alter the way silicon in these areas conducts electricity. Ions are shot onto the surface of the wafer at very high speed.
