Dynamic Hotzone TemperatureControl™ (DHTC)

Yield Improvement within Run, Run-to-Run, System-to-System Repeatability by Optimized Temperature Measurement and Control for PVT Systems

Dynamic Hotzone Temperature Control (DHTC™) for 200 mm & 150 mm SiC Crystal Growth

Yield Enhancement

for SiC Crystal Growth

Minimizing Impact of Misalignment

from Hotzone Degradation, Assembly, & Loading

Patent Pending

Video Processing Software

& Mechanical Hardware

Temperature Measurement Consistency

for 200 mm & 150 mm SiC PVT Systems

Dynamic Hotzone Temperature Control™ is an option that addresses some of the temperature dependent contributors to yield loss.

DHTC™ combines video processing software & mechanical hardware for tracking the center of rotation, position of crucible viewport, and pyrometer alignment to determine, record, and compensate for misalignment of the hotzone for optimized temperature control.

DHTC™ ensures consistent temperature measurement and control during SiC boule growth and run-to-run & system to system repeatability.

DHTC™ Inactive

DHTC™ Active

Real time position tracking of pyrometer and hotzone center to record misalignment.

Precise temperature measurements at the center of viewport.

The actual temperature is 7 oC lower due to the misalignment, contributing to boule yield loss without DHTC™

DHTC™ Features & Options

Improved within Process Run, Run-to-Run & System-to-System Temperature Measurement Consistency for 200 mm & 150 mm SiC Physical Vapor Transport Systems
