What it is

General reference — not yet source-verified

The Tokyo Electron Trias High K is a chemical vapor deposition (CVD) and atomic layer deposition (ALD) system used for depositing high-k dielectric films onto semiconductor wafers.

How it works

The Trias High K system operates as a cluster tool with multiple chambers for different deposition processes.[3][4]

The cluster includes a transfer module, two load ports, and two processing chambers designated PM2 and PM4.[3][4]

PM2 is a high-k CVD reactor; PM4 is a thermal-based deposition chamber, both capable of operating at temperatures from 200 °C up to 500 °C.[3][4]

The Trias High K includes an ozonizer and a water box for process chemistry, and is operated via two touch-screen interfaces.[3][4]

Where it fits in the process flow

General reference — not yet source-verified

The Trias High K is used in the front-end-of-line (FEOL) portion of semiconductor manufacturing, specifically in the gate stack formation where high-k dielectric materials replace traditional silicon dioxide gate oxides.

Deposition of high-k films such as hafnium oxide and nickel oxide occurs after cleaning and before metal gate electrode deposition, forming part of the high-k/metal gate (HKMG) integration scheme.
