H10P GENERIC PROCESSES OR APPARATUS FOR THE MANUFACTURE OR TREATMENT OF DEVICES COVERED BY CLASS H10
Introduced: January 2026
Description
H10P covers generic manufacturing and treatment processes applicable across the broader category of semiconductor and solid-state electronic devices classified in H10. This subclass encompasses general-purpose fabrication techniques, processing methods, and apparatus that are not device-type specific but serve multiple device categories within H10. Examples include wafer preparation, doping processes, thermal treatment, surface modifications, and testing procedures that apply broadly to semiconductor manufacture. Classification here is appropriate when the invention relates to process steps or equipment of general applicability rather than techniques tied to particular device architectures (which would be classified in more specific H10 subclasses).
