Thin-Wafer Support Frames
Specialized support frames for ultra-thin wafers below 100μm, with vacuum-compatible designs and precision anti-warpage flatness.
Overview
As device manufacturers push toward 3D-IC stacking, power device thinning, and backside-illuminated sensors, wafer thicknesses below 100μm — and in advanced cases below 50μm — have become routine, yet these wafers are extraordinarily fragile and prone to warpage once ground below their native mechanical stiffness threshold. Thin-wafer support frames provide a rigid, vacuum-compatible interface that distributes handling forces evenly across the wafer edge, preventing the localized stress concentrations that cause cracking during transport, backgrinding, and dicing.
GINECHIP's thin-wafer support frames maintain flatness below 20μm across the full frame diameter, with optional carrier plate configurations that provide full-back-surface support for the most fragile process steps, such as post-backgrind wafer bonding and Taiko ring debonding. Vacuum-compatible seal surfaces ensure reliable chucking on downstream lithography, inspection, and bonding equipment without introducing particulate contamination.

Applications
Rigid frame support during and after grinding prevents wafer flex that causes micro-cracking in wafers thinned below 100μm.
Ultra-thin die stacks for through-silicon-via integration require dimensionally stable carrier support through multiple bonding and alignment steps.
IGBT and MOSFET backside processing requires thin-wafer handling frames that maintain flatness through backside metallization steps.
Backside-illuminated sensor wafers thinned for optical performance require carrier-plate-supported frames throughout the process flow.
Quality & Certification
Flatness of every thin-wafer support frame is verified via interferometry against a <20μm specification prior to shipment, under ISO 9001:2015 certified quality management. Vacuum seal integrity is leak-tested to ensure reliable chucking performance across repeated use cycles.
