A 1-10 GHz interface engineered SiN/sub x//InP/InGaAs HIGFET technology
Bibliographic record
Abstract
The evolution of an unique interface control layer (ICL) SiN/sub x//lnP/InGaAs Heterojunction Insulated Gate (HIG)FET technology is described from its inception. An In-S monolayer ICL, formed by a novel photoelectrochemical process, is used to reduce and control trap states at the SiN/sub x//InP interface. Buried channel insulated gate ICL HIGFETs fabricated using this approach operate over a large gate voltage range (V/sub gs/=/spl plusmn/8 V) with very low gate leakage (10 nA@V/sub gs/=/spl plusmn/5 V) and I/sub ds/(sat) of 250 mA/mm. Undoped channel ICL HIGFETs exhibit transconductance (g/sub m/) of 40 mS/mm that is limited by conduction through the buffer layer. A 3 to 4 fold improvement in g/sub m/ (140-150 mS/mm) is achieved by using a doped InGaAs channel and eliminating parallel conduction paths through the device. The doped channel HIGFETs show f/sub t/ of 5-6 GHz (Lg=3 /spl mu/m) and f/sub max/ of 10-12 GHz with a power gain of 14.2 dB at 3 GHz. The ICL HIGFET technology has been used to construct simple circuits such as buffer amplifiers with a gain of 7-10 dB at 3 GHz and recently, high frequency sample and hold ICL HIGFET circuits that operate at frequencies of 2 GHz.

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; both teacher heads agree on what is shown here.
