Abstract
This application is directed to an apparatus and process for producing a thin ribbon of semiconductor material. The apparatus includes a moving chill block. The material is deposited in a molten state onto the chill block. A device for generating a magnetic field shapes the deposited molten material on the chill block into the thin ribbon strip.
Claims32
An apparatus for producing a thin ribbon of material, comprising:
- a moving chill block;
- means disposed adjacent the chill block for depositing said material in a molten state onto said chill block;
- and
- means adjacent said chill block for generating a first electromagnetic field to apply pressure to the molten material to squeeze the deposited molten material against said chill block into said thin ribbon of material.

A process for producing a thin ribbon of material, comprising the steps of:
- providing a moving chill block;
- depositing said material in a molten state onto said chill block;
- generating a first electromagnetic field for applying pressure to shape the deposited molten material on said chill block into said thin ribbon;
- and
- squeezing the molten material against said chill block with the pressure of the first electromagnetic field to form said thin ribbon.
