Title:
DEVICE FOR HEAT TREATMENT OF SEMICONDUCTOR
Document Type and Number:
Japanese Patent JPH0741397
Kind Code:
A
Abstract:

PURPOSE: To provide a heat treating device for semiconductors in which a semiconductor crystal can be subjected to multistage heat treatment at a high temp., a block sample can be heat treated, and rapid heating and rapid cooling can be done.

CONSTITUTION: This heat treating device 1 for semiconductors is equipped with a silicon carbide heater 5 as a heat generator and a silicon carbide tube 3 as a reaction tube. In this device, the max. temp. for heat treatment of a sample is ≥1400°C with ≥50mm soaking length, the controllable cooling rate is 0-30°C/min in 1200-1400°C temp. range and 0-25°C/min in 100-1200°C temp. range, and the controllable temp. rising rate is 0-15°C/min in 1200-1400°C temp. range.
