About Ponda

Who are we?

Ponda Grinding (Also known as Fangda) is a comprehensive equipment manufacturer that integrates research, development, production, and sales. Our product range includes traditional flat finishing machines like flat lapping and polishing machines, advanced automation equipment such as wafer grinders and edge grinders, and spherical and aspherical optical grinding and polishing equipment. We also provide all necessary consumables to support our equipment.

Wafering

Wafering series focuses on producing thinner, higher precision semiconductor wafers.

Optics Surfacing

Optics surfacing series is applied to process spherical and aspherical workpieces such as lens.

Flat Finishing

Wafering

In semiconductor manufacturing, users require thinner, more uniform wafers with higher yield to be packaged into chips. Therefore, the Wafering series is specifically developed to meet these needs.

Spherical and Aspherical Processing

In optical machining, multi-axis CNC equipment is usually required to process spherical or aspherical lenses in order to achieve ultra-precise control over the shape of the workpiece.

Precision Mold

Flat Finishing

Products like static-pressure bearing and linear slider, high-precision optical lens, sealing valve, benchmark block require flat finishing equipment.

Where are Ponda's machines used in semiconductor industry?

Our semiconductor equipment is mainly used in wafer manufacturing and wafer fabrication for grinding and polishing, as well as in post-packaging grinding. We also produce supporting equipment to complete the processing chain.

CMP Finishing

The edges of sliced wafers are sharp and fragile. By applying edge beveling to form arc-shaped profiles, stress concentration points are eliminated.

The surface of a sliced wafer is not flat. Through grinding, the wafer can be thinned while achieving improved flatness.

Backgrinding thins the wafer while protecting the circuits. Subsequently, CMP is used to remove the remaining damage layer and planarize the wafer. The thinned wafer also reduces stress damage during dicing.

CMP Finishing

Sapphire wafers have high brittleness, and wax bonding is used to prevent surface cracks or edge chipping. This also significantly reduces deformation during processing and ensures good yield and precision in subsequent processes.

After sapphire grinding, lapping is used to reduce the damage layer left by grinding and further improve surface roughness, enhancing the efficiency of polishing. Polishing then completely removes the damage layer and achieves a smooth and shinny surface.

During the backgrinding stage of sapphire wafers, specially-made films are used to protect the circuits. The thinning process ends after lapping and CMP finishing.
