Thermco’s Model 5100 and 5200 Diffusion Furnaces are configurable from two to four-process chamber systems used for processing Semiconductor, PV, LED, Nano and MEMS substrates up to 150 mm in diameter.

5100 series has a 750mm flat zone and the 5200 series has a 1,100mm flat zone leading to greater wafer processing capacity for the 5200. The 5100 and 5200 can be interfaced with a wide range of automation solutions, such as elevators and fully automatic cassette-to-cassette automation packages.

The furnace mainframe is constructed of welded and formed cold rolled steel, painted with industrial-grade water-based enamel paint. Parts and components that are subjected to elevated temperatures are constructed from stainless steel.

Thermco Systems have thermal process tools designed with your emerging technologies in mind


The furnace is controlled by the industry-leading Thermco TMX controller, recognised as one of the most flexible and reliable furnace control systems available with an installed base of thousands of units. The TMX control system and PCMUX combines the tried and trusted recipe and system control formats of earlier generation TMX products with new updated, reliable software on PC-based hardware with improved graphics, control and AI functions. The system comprises one MUX computer for recipe generation and status overview and one control computer per tube.
