Vacuum Process Oven for up to 300 x 300 mm substrate size and temperature up to 1000 °C

Lamp heated rapid thermal annealing RTA and rapid thermal processing RTP equipment are using lamp heating in order to ramp up and cool down semiconductor wafers pretty fast. This equipment is therefore mainly used for applications where the substrate needs to be brought to a certain temperature just only for short time. The high ramp rates allow a short overall process time and keep the thermal budget (this is the total time of a wafer, being exposed to high temperature) of the wafer low. Because of the design of the heaters, these RTA and RTP tools are used mainly for single wafer treatment. Wafers have to be treated one by one. This is not as important as for other batch thermal processes, which use vertical furnaces and horizontal furnaces, because the process time is very short anyway. However wafer handling takes a substantial part of process time.
The VPO-300 is a cold wall oven.

    UniTemp RTP furnaces offer a unique lamp arrangement with upper and lower cross lamp arrays. The temperature distribution tool provides outstanding and unparalleled temperature uniformity resulting in process repeatability.


    Perfect for wafer up to 300 mm or substrates  up to 300 x 300 mm.

    Through the chamber walls there can be led different feed throughs, like a window for optical measurement tools, thermocouple feed through, gas inlets, etc.
    The process cycles are very short due to fast reaching of vacuum with 10E -3 hPa.

    Here are the most feasable applications:
