DC power for resistance heating in precise MOCVD processes

Metal Organic Chemical Vapor Phase Deposition (MOCVD) is a highly complex procedure for the growth of crystalline layers. MOCVD is implemented for the manufacture of light emitting diodes (LEDs), lasers, transistors, solar cells and other electronic and opto-electronic components, for example, and is the key technology for future markets with high growth potential. TruHeat DC 3000 is the perfect candidate for these applications.

High efficiency and innovative GaN generator in the 2.45-GHz-ISM band for high-tech microwave applications

To date, the main obstacle and greatest disadvantage in the industrialization of microwave processes has been the lack of "options". Up to now, only mechanically mobile components such as rotating plates, agitators, etc. were available to influence the homogeneity of the heating process and to facilitate a targeted temperature distribution and a reproducible heating process.
