The AP furnaces provide dry/wet oxidation, dopant diffusion, annealing, and sintering process, which are transport dominant, i.e. the reaction rate is controlled by the transportation and/or non-MOS and MEMS terminologies are used interchangeably in this manual. Pre-Furnace Wafer Cleaning (Rules/Procedure). · Diffusion is the process of molecules moving from an area of high concentration to a low one. It occurs routinely within and between liquids, gases, and solids in daily life. This process is exploited by diffusion furnaces, which elevate the temperature of workpieces and introduce gaseous elements to encourage solid state www.doorway.ruted Reading Time: 3 mins. Modulab Phosphorus Diffusion Furnace Description. A solid source phosphorous diffusion. Operating Manual *Note that the instructions below may not contain the most recent updates. Please refer to the manuals printed and posted at the equipment. Safety and Restrictions. Safety. The furnace gets extremely hot and remains hot to the touch hours.

This set of manuals explains how to operate a Horizontal Diffusion/LPCVD furnace. Refer to the Touchscreen reference manual (M) or the TSC-2 reference manual (M) for a full description of all operating screens. For information about processing refer to the Process Manual (Mxxx).
Diffusion furnaces comprise cylindrical heating chambers that can be arranged either vertically or horizontally. Each orientation enables operators to maximize thermal efficiency by offering a uniform distance between silicon wafers and the radiating surface of heating elements. What is a Diffusion Furnace? A diffusion furnace is a thermal processing unit with a cylindrical heating chamber that can be oriented either horizontally or vertically. This enables circular workpieces to be processed with outstanding thermal uniformity due to the equidistant surfaces radiating heat. allotted time, ramp the furnace down to °C (or 0°C if finished with furnace), pull the quartz boat and remove the wafers and set them aside to cool. When the temperature drops below °C the nitrogen can be turned off. Figure 5 Inserting the boat into the Boron Diffusion Furnace. Lab 1.
