Assignee: APPLIED MATERIALS, INC.
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G

Claim 16:
17. A system comprising:
an optical detector, operatively coupled to a switch device, to selectively measure material thickness data resulting from an iteration of an etch process;
a memory storing instructions to facilitate an etch recipe development process; and
at least one processing device operatively coupled to the memory, the optical detector and the switch device, wherein the instructions, upon execution by the at least one processing device, cause the at least one processing device to facilitate the etch recipe development process by determining one or more etch parameters based on at least first material thickness data for a first material and second material thickness data for a second material, wherein the first material is located at a first reflectometry measurement point and the second material is located at a second reflectometry measurement point different from the first reflectometry measurement point.
