Wafer Back Grinding Wheel

The wafer back grinding process is crucial for achieving the desired thickness and optimizing the electrical and thermal performance of semiconductor devices. Precision, control, and the use of specialized equipment and grinding wheels are key factors in ensuring the success of this critical manufacturing step.

Tape Lamination: The semiconductor wafer is mounted onto a support, often using adhesive tape. Tape lamination is conducted to attach a layer of tape onto the front surface of the semiconductor wafer to provide stability during the process.

Wafer Grinding and Thinning:Utilizing a specialized grinding machine equipped with a wafer back grinding wheel, often made of materials like vitrified diamond, material is precisely removed from the backside of the wafer. This step is crucial for achieving the desired thinness of the wafer. A precision grinding process is employed to thin the wafer from the backside, gradually reducing its thickness to meet desired specifications.

Wafer Mounting: Prior to the sawing process, which separates individual chips from the wafer, wafer mounting is carried out. During this stage, the thinned wafer is carefully mounted onto a rigid substrate or carrier, typically utilizing the tape applied in the first step.
