Assignee: APPLIED MATERIALS, INC.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. An apparatus for substrate stress control, comprising:
a beam scanner to scan an ion beam with respect to a substrate, the substrate including a stress compensation layer;
a user interface, coupled to the beam scanner;
a controller, coupled to the beam scanner and the user interface, the controller comprising:
a processor; and
a memory unit coupled to the processor, including a scan routine, the scan routine operative on the processor to receive substrate stress information from the user interface and generate an implant pattern to control the beam scanner, the implant pattern to generate an anisotropic stress within the stress compensation layer,
the scan routine comprising an implant pattern processor and a scan control processor, the implant pattern processor operative to:
receive a set of substrate stress information, indicative of a stress state in the substrate; and
calculate the implant pattern, based upon the substrate stress information,
wherein the substrate stress information comprises at least one of a substrate thickness of the substrate, a thickness of the stress compensation layer, and an anisotropic curvature of the substrate.
