How to Reduce Wafer Stress & Damage After the Backgrinding …

Wafer backgrinding is an essential semiconductor device fabrication step that aims to reduce wafer thickness to generate ultra-flat wafers. Wafers are generally about 750 μm thick to guarantee mechanical stability and to prevent warping during high-temperature processing. But several methods can be done to safely thin wafers even more.

The Applications of a TAIKO Wafer | Grinding | Solutions | DISCO ...

Application processing examples. The TAIKO process is a wafer backgrinding method developed by DISCO. This process method leaves a ring (approximately 3 mm) on the wafer outer edge and thin grinds only the inner area of the backside wafer. By leaving this edge ring, it is possible to reduce the risks of wafer breakage or edge chipping.

Semiconductor Back-Grinding - IDC-Online

A typical wafer supplied from the 'wafer fab' is 600–750µm thick. This thickness is determined by the stresses during processing, and the requirements for handling robustness. However, for most IC assembly uses the wafer thickness is reduced to around 50% of this, partly for mechanical reasons, but also to improve thermal transfer.

The back-end process: Step 3 – Wafer backgrinding

For wafers with diameters of 200 mm, it is typical to start with a wafer thickness of roughly 720 µm and grind it to a thickness of 150 µm or less. The coarse grinding typically removes approximately 90 percent of the excess material. A typical two-step backgrinding operation will use dual spindles with grinding wheels mounted on each spindle.

Wafer Backgrind - AnySilicon Semipedia

Wafer Backgrind. Wafer backgriding is a process of thinning the wafer to meet the required thickness before packaging the die into its package. Wafer backgrinding is also called wafer thinning or wafer back-lapping. Backgrinding process is not a mandatory step in ASIC production, however, thinner semiconductor packages has made it unavoidable.
