Slip Resistant Ceramic Horizontal Semiconductor Wafer Boat Semiconductor Processing Components

Slip Resistant Ceramic Horizontal Semiconductor Wafer Boat Semiconductor Processing Components

Key words : Horizontal Semiconductor Wafer Boat

The invention relates to a vertical rack for semiconductor wafer processing having strictly horizontally disposed arms wherein each arm has a rounded tip and a smooth (Ra < 1 < mu >m) upper surface.

The manufacture of semiconductor devices such as integrated circuits typically requires heat treating silicon wafers in the presence of reactive gases. During this process, the temperatures and gas concentrations to which the devices are exposed must be carefully controlled, as the devices often include circuitry elements less than 1 um in size which are sensitive to minute variations in the processing environment.

Horizontal Semiconductor Wafer Boat

Because a wafer processed on a vertical rack experiences less of a temperature gradient over its face (as compared to a wafer processed in a horizontal boat), semiconductor manufacturers are increasingly turning to vertical furnaces. There is, however, a drawback to vertical furnacing. The wafers disposed on a conventional vertical rack are supported at their outside edge only. As such, the areas of the wafer resting on these teeth experience higher stress than the rest of the wafer. When temperatures in the furnace exceed about 1000°C, these stresses often become significant and portions of the single crystal wafer move relative to each other along crystallographic plates in response to that stress. This phenomenon, called "slip", effectively destroys the value of the semiconductor devices located in the area of the wafer where slip has occurred.
