Abstract
An apparatus and process for producing thin ribbon of semiconductor material. A device is provided for feeding the material onto a moving chill block. A first electromagnetic field is generated to heat the material in the solid condition into a molten drop and then to shape the molten drop into a thin ribbon shape prior to the contact of the material with the chill block.
Claims38
An apparatus for producing a thin ribbon of material, comprising:
- a moving chill block;
- means adjacent said chill block for feeding said material onto said chill block;
- and
- means associated with the feed means for generating a first electromagnetic field to heat said material in the solid condition into a molten drop and to shape said molten drop into a thin ribbon shape prior to contact of said molten material with said chill block.
An apparatus for producing a thin ribbon of semiconductor material, comprising:
- a moving chill block;
- means adjacent said chill block for feeding said semiconductor material onto said chill block;
- and
- means associated with the feed means for generating a first electromagnetic field to heat said material in the solid condition into a molten drop and to shape said molten drop into a thin ribbon shape prior to contact of said molten semiconductor material with said chill block.
An apparatus for producing a thin ribbon of material, comprising:
- a moving chill block;
- means adjacent said chill block for feeding said material onto said chill block;
- means associated with the feed means for generating a fifth electromagnetic field to heat said material in the solid condition into a molten drop;
- and
- means adjacent said chill block for generating a fourth electromagnetic field to shape said molten drop into a thin ribbon shape prior to contact of said molten material with said chill block.
An apparatus for producing a thin ribbon of material, comprising:
- a moving chill block;
- means disposed adjacent said chill block for feeding said material onto said chill block;
- means associated with the feed means for generating a first electromagnetic field to heat said material in the solid condition into a molten drop and to shape said molten drop into a thin ribbon shape prior to contact of said molten material with said chill block;
- and
- means adjacent said chill block for generating a sixth electromagnetic field to apply pressure to the molten material to squeeze the deposited molten material on said chill block into said thin ribbon of material.
The process of producing a thin ribbon of material comprising the steps of:
- providing a moving chill block;
- feeding said material in the molten condition onto said chill block;
- and
- generating a first electromagnetic field to heat the material in the solid condition into a molten drop and to shape the molten drop into a thin ribbon shape prior to contact of the molten material with the chill block.
The process of producing a thin ribbon of material comprising the steps of:
- providing a moving chill block;
- generating a fifth electromagnetic field to heat said material in the solid condition into a molten drop;
- generating a fourth electromagnetic field to shape said molten drop into a thin ribbon shape of molten material prior to contact of said thin ribbon of said molten material with said chill block;
- and
- feeding said material onto said chill block.
