Abstract

fetched live from OpenAlex

In this paper, a micro bridge mechanism is presented for on-chip lifting of micro structures. The micro bridge mechanism is made of the thin film with negative residual stress gradient across the thickness. It can be used for constructing vertically moving micro devices or calibrating the residual stress in micro fabricated thin films. The principle of the micro bridge mechanism is explained. An approximation model is developed to estimate the lifting height of the bridge mechanism. Prototypes with various dimensions are fabricated using the MetalMUMPs process and were experimentally measured. Experimental measurements show that even being limited by silicon nitride beams, a lifting height of 30-50 μm has been achieved by the micro bridge mechanism.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
