摘要:
The thermal flux processing device includes a continuous wave electromagnetic radiation source, a stage, optics, and a translation mechanism. The continuous wave electromagnetic radiation source is preferably a diode/s. The stage is configured to receive a semiconductor substrate thereon. The optics are preferably disposed between the continuous wave electromagnetic radiation source and the stage. Also, the optics are configured to focus continuous wave electromagnetic radiation from the continuous wave electromagnetic radiation source into a line of continuous wave electromagnetic radiation on an upper surface of the semiconductor substrate. A length of the line of continuous wave electromagnetic radiation extends across an entire width of the semiconductor substrate. The translation mechanism is configured to translate the stage and the line of continuous wave electromagnetic radiation relative to one another, and preferably includes a chuck for securely grasping the substrate. A method for thermally processing a semiconductor substrate is also provided.

The thermal processing device includes a stage, a continuous wave electromagnetic radiation source, a series of lenses, a translation mechanism, a detection module, a three-dimensional auto-focus, and a computer system. The stage is configured to receive a substrate thereon. The continuous wave electromagnetic radiation source is disposed adjacent the stage, and is configured to emit continuous wave electromagnetic radiation along a path towards the substrate. The series of lenses is disposed between the continuous wave electromagnetic radiation source and the stage, and are configured to condense the continuous wave electromagnetic radiation into a line of continuous wave electromagnetic radiation on a surface of the substrate. The translation mechanism is configured to translate the stage and the line of continuous wave electromagnetic radiation relative to one another. The detection module is positioned within the path, and is configured to detect continuous wave electromagnetic radiation.
摘要:
A method for activating implanted dopants in a semiconductor substrate to form shallow junctions comprises the steps of: maintaining gas pressure in the processing chamber at a level significantly lower than atmospheric pressure, providing a flow of a carrier gas into the processing chamber, subjecting the substrate to a temperature treatment process, and introducing oxygen into the processing chamber during all or part of the temperature treatment process.
摘要:
A method of forming a semiconductor substrate, comprising the steps of: providing a device substrate of a first conductivity type having a first surface and a second surface, and a handle substrate; depositing a dopant in the first surface of the wafer; diffusing the dopant through the wafer from the first surface toward the second surface, thereby forming a well; bonding the first surface of the device wafer to the handle substrate; and thinning the device substrate to yield a final device layer with a retrograde well. The dopant may be of the first or a second conductivity type.
摘要:
A method for dissipating accumulated charge in a trench isolation structure, comprising the steps of: forming a contact region of an area having a cross section greater than the width of the isolation structure; and coupling the isolation structure to a charge dissipation means.
摘要:
A process is disclosed for forming high-performance, high voltage PNP and NPN power transistors in a conventional monolithic, planar, epitaxial PNP junction isolated integrated circuit. The process permits independently optimizing the NPN and PNP power trransitors. Where high-voltage devices are desired a field threshold adjustment implant is applied. It also includes provisions for testing critical portions of the process at appropriate points.
