Abstract:

The present invention consists of a method for imparting asymmetry to a truncated annular wafer by either rounding one corner of the orientation flat, or rounding one corner of a notch. This novel method of rounding corners impart a visual and/or tactile asymmetry which can be utilized by a person in order to differentiate between the two different sides of the wafer. This inventive wafer design and method for making an asymmetric wafer is especially useful in the field of semiconductor technology and may be used on sapphire crystal wafers or any other class of wafer.

Abstract:

A self-cleaning, gas-fired tunnel oven is provided. One embodiment of the oven provides a self-cleaning, gas-fired tunnel oven for cooking food products. The oven includes a control system that regulates oven temperature during a pyrolitic, self-cleaning procedure for incinerating contaminants that accumulate inside; a burner for cooking food products and incinerating contaminants; a modulating air and fuel control system arranged for proportionally delivering air and fuel to the burner; a plurality of convection air fingers for directing heated air toward the food products; a collapsible conveyor, capable of fitting into the oven when collapsed, for passing the food products through the oven; a plurality of blowers, each having a dedicated speed controller; a floating cooking chamber; and a vent system that maintains a negative pressure in the oven during the self-cleaning procedure
