Development of DFG8561: A Fully Automatic Grinder Supporting Φ300 mm Wafers

DISCO CORPORATION, a semiconductor manufacturing equipment manufacturer (Head Office: Ota-ku, Tokyo; President: Kazuma Sekiya), has developed DFG8561, a fully automatic grinder that supports Φ300 mm wafers.
This equipment will be exhibited at SEMICON Japan 2025 (December 17-19, Tokyo Big Sight).

Developmental Background

In the semiconductor back-end/OSAT industry, wafer thinning (grinding) has become a standard process to achieve a low profile and higher integration. In addition, migration from 5-/6-inch to 8-inch and 300 mm wafers is accelerating in order to improve production efficiency for automotive and home-appliance MCUs, analog ICs, and sensors. To address these thinning needs, DISCO has developed DFG8561, a next-generation grinder that supports 300 mm wafers.

DFG8561

Features

  • Improved wafer thickness accuracy
  • Through improvements such as adoption of a rotation axis with low vibration and low thermal expansion on the wafer retaining table, the thickness accuracy within the wafer and between wafers has been improved.

  • Compatible with a wide range of materials
  • Installed with a high-power spindle (6.3 kW), enabling processing of difficult-to-grind materials such as SiC and sapphire.

  • Improved productivity
    • Processing time reduced by optimizing the transfer/cleaning mechanism, making the productivity 1.6x higher compared to the conventional model.
    • With a built-in vacuum unit, the footprint is reduced by 12% compared to the conventional model, improving the productivity per unit floor area.

  • Improved usability
    • The processing recipe can be configured for each wafer in the same cassette, enabling multi-variety low-volume production.
    • Main types of data are displayed as graphs on a large, 19-inch monitor.
