Class Information
Number: 117/13
Name: Single-crystal, oriented-crystal, and epitaxy growth processes; non-coating apparatus therefor > Processes of growth from liquid or supercritical state > Having pulling during growth (e.g., czochralski method, zone drawing)
Description: Subject matter characterized by bringing a seed* into contact with a liquid precursor* (or nutrient*) media to initiate and conduct the growth process by then withdrawing it under conditions which permit crystal formation while pulling.
