Product Details
6 Inch 153mm 156mm 159mm Thickness 350um 0.5mmt Sapphire Carrier Substrate Wafer SSP DSP
Product Description:
Sapphire bonding sheet is used for thinning and polishing of gallium arsenide wafers Due to the weight and pressure imposed by the equipment, the traditional gallium arsenide wafer thinning process is liable to cause wafer fragmentation, or the surface stress accumulates to form a coil during the thinning process, and the product performance is seriously lost. The metal disk used for thinning is liable to produce metal pollution, and the wafer adhesive and chemical grinding fluid are liable to introduce pollution.
The new thinning process uses sapphire wafer (diameter slightly larger than the target wafer) as a carrier to bond with gallium arsenide wafer under high-temperature conditions. The gallium arsenide/sapphire bonding wafer is attached to a ceramic disk, thined and polished by a special fixture, and then melted in a high-temperature wash to separate the sapphire and gallium arsenide wafer.
The new thinning process can be used for the thinning processing of gallium arsenide and various semiconductor wafers, and the carrier material can be sapphire, glass and other polished wafers.
Sapphire is the mainstream carrier choice because of its superior physical and chemical properties and crystal structure. The sapphire carrier launched by our company matches the industry standard thinning equipment requirements with a diameter of 104mm for 4 inches. The 6-inch wafer has a diameter of 156mm or 159mm, slightly larger than the standard 4-inch, 6-inch wafer, and the polishing surface roughness.
