SYSTEM AND METHOD OF PRODUCING MONOCRYSTALLINE LAYERS ON A SUBSTRATE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240052520 titled 'SYSTEM AND METHOD OF PRODUCING MONOCRYSTALLINE LAYERS ON A SUBSTRATE
Simplified Explanation
The patent application describes a system for producing an epitaxial monocrystalline layer on a substrate using a cavity to accommodate a source material and the substrate, along with heating means to heat the cavity. The inner container includes spacer elements to support the substrate at a predetermined distance above the source material.
- Inner container with spacer elements to support substrate above source material
- Insulation container to accommodate inner container
- Outer container to accommodate insulation and inner containers
- Heating means outside outer container to heat the cavity
- Potential Applications
- Semiconductor manufacturing
- Solar cell production
- LED manufacturing
- Problems Solved
- Ensures uniform epitaxial monocrystalline layer growth
- Prevents contamination of the substrate
- Facilitates precise control of layer thickness
- Benefits
- Improved quality of epitaxial layers
- Enhanced efficiency in manufacturing processes
- Cost-effective production of monocrystalline layers
Original Abstract Submitted
a system () for producing an epitaxial monocrystalline layer on a substrate () comprising: an inner container () defining a cavity () for accommodating a source material () and the substrate (); an insulation container () arranged to accommodate the inner container () therein; an outer container () arranged to accommodate the insulation container () and the inner container () therein; and heating means () arranged outside the outer container () and configured to heat the cavity (), wherein the inner container () comprises a plurality of spacer elements () arranged to support the substrate () at a predetermined distance above a solid monolithic source material (), wherein each spacer element () comprises a base portion () and a top portion (), wherein at least part of the top portion () tapers towards an apex () arranged to contact the substrate (). a corresponding method is also disclosed.
