Effects of Inlet Flow Rates on Purge Durations in an Atomic Layer Deposition Process
Bibliographic record
Abstract
The effects of inlet flow rates on the purge durations in an atomic layer deposition (ALD) process are investigated through the simulation of three-dimensional laminar multicomponent flow in viscous flow reactors. The operating pressure and temperature are 10 torr (1333 Pa) and 300 C, respectively. Purge durations in reactors with inlet located on the top surface of the reactor are compared with those in a base reactor with one inlet at the bottom surface of the reactor. It is found that purge durations are reduced by an increase in the flow rates, but they are independent from the number of inlets if the flow rates are maintained equal among different reactors. One exception is the reactor with one inlet at the center of the top surface of the reactor, which experiences the longest purge durations, most likely due to the axisymmetric gas injection in this reactor. The acquired results will provide a better understanding about designing efficient viscous flow reactors to reduce both purge duration and gas consumption.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
