Abstract:
1. A wafer carrier track for levitating and traversing a wafer carrier within a vapor deposition reactor system, comprising: a first track assembly having a first upper section disposed over a first lower section in a first vapor deposition reactor; a first gas cavity formed between the first upper and lower sections of the first track assembly; a first guide path extending along a first upper surface of the first upper section; two first side surfaces extending along and above the first guide path and parallel to each other, wherein the first guide path extends between the first two side surfaces; a first plurality of gas holes within the first guide path and extending from the first upper surface of the first upper section, through the first upper section, and into the first gas cavity; and a first upper lap joint disposed at one end of the first track assembly and a first lower lap joint disposed at the opposite end of the first track assembly, wherein the first upper lap joint extends a portion of the first guide path and the first two side surfaces and the first lower lap joint comprises a first upper surface extending further than the first guide path and the first two side surfaces of the first track assembly; a second track assembly having a second upper section disposed over a second lower section in a second vapor deposition reactor coupled to the first vapor deposition reactor at an interface; a second gas cavity formed between the second upper and lower sections of the second track assembly;
