Abstract:
Methods and apparatuses relate to implanting a surface of a semiconductor substrate with dopants, making undoped semiconductor material directly on the surface implanted with the dopants, and making a transistor with a transistor channel in the undoped semiconductor material, such that the transistor channel of the transistor remains undoped throughout manufacture of the integrated circuit.

Claim (Index 1):
A method of performing channel stop doping in an integrated circuit, comprising:\n implanting a first part of a surface of a semiconductor substrate with n-type dopants and a second part of the surface with p-type dopants; making epitaxial semiconductor material directly on the first part of the surface implanted with the n-type dopants and on the second part of the surface implanted with the p-type dopants, the epitaxial semiconductor material having a dopant concentration on the first part of the surface and on the second part of the surface, the dopant concentration changing by a decade over a depth of less than 3 nanometers at an interface between the epitaxial semiconductor material and the semiconductor substrate under process conditions including temperature developed to cause the dopant concentration changing at the interface; and making a transistor with a transistor channel in the epitaxial semiconductor material, such that the transistor channel, in the epitaxial semiconductor material, of the transistor remains essentially undoped throughout manufacture of the integrated circuit.
