Abstract:
A bonded substrate for epitaxial growth and a method for forming the same are disclosed. The method includes steps of providing a first substrate, which has a first dopant concentration; providing a second substrate, which has a second dopant concentration, wherein the second dopant concentration is lower than the first dopant concentration; directly bonding a first surface of the first substrate with a second surface of the second substrate to form a bonded substrate; annealing the bonded substrate to form a high impedance layer in the bonded substrate; and removing part of the second substrate to expose the high impedance layer depending on the requirements whereby, the bonded substrate formed by the method could have a heavily doped substrate which includes a stronger strength and the impedance layer formed thereon, which could effectively increase the substrate strength, reduce the leakage current, and sustains a higher breakdown voltage.

Claim (Index 1):
A method for forming a bonded substrate for epitaxial growth, comprising:\n A. providing a first substrate, which has a first dopant concentration; B. providing a second substrate, which has a second dopant concentration, wherein the second dopant concentration is lower than the first dopant concentration; C. directly bonding a first surface of the first substrate with a second surface of the second substrate to form a bonded substrate; and D. annealing the bonded substrate to form a high impedance layer in the bonded substrate.
