Enhance Your Manufacturing Precision and Throughput with Wave3000’s Cutting-Edge Features

In the evolving landscape of semiconductor manufacturing, Fan-Out Wafer Level Packaging (FOWLP) has emerged as a transformative technology, offering substantial benefits such as enhanced electrical performance, reduced form factor, and cost-efficiency. However, FOWLP also introduces significant challenges related to deformation and wafer warpage. Effective management of these issues is crucial for maintaining high yield rates and reliable device performance. ERS Electronic GmbH addresses these challenges with its cutting-edge warpage metrology tool, the Wave3000.

Impact of Warpage on Manufacturing and Product Performance

Warpage refers to the deformation of wafers during the packaging process, resulting from factors such as the coefficient of thermal expansion (CTE) mismatch between the die and the substrate, residual stresses, and material properties. This deformation can manifest as bowing, twisting, or other irregularities that severely impact the manufacturing process and the final product's performance.

Warpage can disrupt various stages of the FOWLP process:

1. Via Formation: Warpage-induced misalignment can result in incomplete via filling, compromising electrical connections.

2. Redistribution Layer (RDL) Formation: Non-uniform thickness and misalignment can affect the RDL’s performance.

3. Bumping process: Warpage can cause non-uniform solder application, leading to voids and weak joints.

4. Package Singulation: During the sawing process, warpage can lead to mold cracking and RDL delamination, reducing yield and reliability.
