Manufacturing Processes of Germanium Sputtering Targets

1. Melt the metallic germanium and inject it into the feedstock area, allowing it to solidify at a cooling rate of 1 to 3°C per minute to obtain germanium blocks.
2. Add the germanium blocks to the crucible body and cover with the crucible lid.
3. Vertically place the crucible body containing the germanium blocks into the heating device, ensuring it stands on the support base, positioning the molten zone within the heating area of the device while keeping the feedstock area outside the heating zone.
4. Heat the molten zone of the crucible body in the heating device at a rate of 5 to 10°C per minute, maintaining it at 980 to 1050°C for 2 to 5 hours. Upon completion, rotate the support base at a speed of 8 to 15 revolutions per minute to expel internal oxygen, thereby enhancing the density of the target material.
5. After rotating the support base for 3 to 6 minutes, preferably 5 minutes, lower it to remove the crucible body for natural cooling until it reaches room temperature.
6. Extract the germanium target precursor from the crucible body, removing parts from both ends. Specifically, remove the lower portion located in the feedstock area and trim the upper end by 3 to 5 millimeters. This yields the germanium target material, which can then be cut into the desired target size as needed.

The germanium target material prepared through this method allows for the production of targets in various sizes within a specific range, facilitating convenient large-scale manufacturing. Simultaneously, as the crucible body is placed on the support base and rotated during production, oxygen within the germanium target material is eliminated. This process results in targets with a density exceeding 99%, significantly enhancing the overall density of the germanium targets.

Germanium Sputtering Targets Production Process Control

1. Incoming Materials Management

• Procure high-quality metallic germanium raw materials from reliable suppliers.
• Conduct rigorous incoming inspections on the raw materials, assessing appearance, purity, particle size, and chemical properties.
• Ensure appropriate storage conditions for the raw materials to prevent moisture, contamination, or other adverse effects.
• Precise Inventory Management:

2. Process Management

• Material Selection: Use high purity germanium materials to ensure the purity and stability of the final product. Impurities can degrade the performance of the germanium target.
• Crucible Cleanliness: Make sure the crucible is clean and free of impurities or residues. Any impurities or contamination may affect the purity and quality of the germanium target material.
• Temperature Control: Control the temperature of the heating unit to ensure that the germanium material melts and cools uniformly. Excessive or uneven temperatures may result in uneven or defective target structure.
• Melting Process Control: Controls the melting and cooling rate of the germanium material. Rates that are too fast or too slow may result in an uneven internal structure of the target, affecting the performance of the final product.
• Oxygen Drainage: During the manufacturing process, oxygen is drained from the crucible to avoid the effects of oxidation on the germanium material. This can be accomplished by methods such as rotating the support table.
• Cooling Control: Control the cooling process of the target material so that it cools uniformly and stably to room temperature. Rapid or uneven cooling may cause internal stresses and cracks.

3. Quality Assurance

Germanium sputtering targets will undergo inspection by the quality and technical supervision department to ensure that the product quality complies with the specified standards or the terms outlined in the purchase order (contract).

4. Monitoring and Test Equipment Management

• Appearance Inspection: Check the surface of the target material for smoothness, absence of cracks, bubbles, or any visible defects.
• Dimensional Inspection: Measure the target material's dimensions, thickness, and geometric shape to ensure compliance with specified standards and requirements.
• Chemical Analysis: Employ chemical analysis methods like X-ray Fluorescence Spectroscopy (XRF), Inductively Coupled Plasma Mass Spectrometry (ICP-MS), etc., to confirm that the chemical composition meets the standards.
• Electrical Property Testing: Conduct tests on the target material's electrical properties such as resistivity, conductivity, etc., to verify if they meet the expected performance.
• Structural and Microscopic Observation: Utilize microscopy or Scanning Electron Microscopy (SEM) to observe the internal structure and surface morphology of the target material.
• Optical Property Testing: Perform tests on optical properties like transmittance, reflectance.
