2.\u00a0<\/span><\/span><\/span>TGV\u00a0<\/span><\/span><\/span>process analysis<\/span><\/span><\/span><\/h1>\n

The TGV\u00a0<\/span><\/span>(Through Glass Via) process is a technology for making vertical interconnected through holes on a glass substrate. It can achieve through holes with a diameter of less than 10\u03bcm\u00a0<\/span><\/span>and\u00a0<\/span><\/span>is mainly used in advanced packaging, radio frequency (RF), MEMS (microelectromechanical systems) and optoelectronic integration.<\/span><\/span><\/p>\n

1. What is TGV metallization?<\/span><\/span><\/p>\n

TGV metallization, in simple terms, is a technology that creates tiny through holes on a glass substrate and fills these through holes with metal to achieve electrical connection and signal transmission. Glass substrates have advantages such as good electrical insulation, thermal stability, and a low dielectric constant, making them very suitable for use in electronic devices. By achieving through-hole metallization on a glass substrate, it is possible to provide efficient interconnection channels for electronic components such as chips, greatly improving the performance of electronic devices.\u00a0<\/span><\/span><\/p>\n

2. TGV metallization process steps<\/span><\/span><\/p>\n

Glass substrate selection and processing\u00a0: First, we need to select the appropriate glass material, such as high-quality borosilicate glass or quartz glass, which have low thermal expansion coefficient and high dielectric properties. After selection, the glass substrate needs to be carefully cleaned and pre-processed to ensure that its surface is clean and free of defects, laying a good foundation for subsequent processes.<\/span><\/span><\/p>\n

Through-hole production\u00a0<\/span><\/span>: There are many micro-machining technologies available for this step, such as sandblasting, ultrasonic drilling, wet etching, deep reactive ion etching (DRIE), photosensitive etching, laser etching, etc. Among them, laser induced deep etching (LIDE) is a more advanced method, which can accurately control the aperture size and high aspect ratio through-hole structure, while keeping the sidewall smooth and reducing cracks and roughness.<\/span><\/span><\/p>\n

Seed layer deposition\u00a0<\/span><\/span>: A very thin metal seed layer is deposited on the inner wall of the glass through hole, usually using a sputtering process. The role of this seed layer is to provide a basis for the attachment of copper or other conductive materials during subsequent electroplating, just like sowing seeds on the land to prepare for subsequent growth.<\/span><\/span><\/p>\n

Filling with conductive materials\u00a0<\/span><\/span>: Conductive materials such as copper are filled into the prepared through-holes through the electroplating process to form a vertically interconnected conductive path. This process must ensure that the through-holes are completely filled without voids, otherwise the electrical performance will be affected. In large-scale production, it is necessary to precisely control the parameters of electroplating, such as current density, electroplating time, etc., to ensure that each through-hole can be filled with metal with high quality.\u00a0<\/span><\/span><\/p>\n

Planarization and film removal\u00a0<\/span><\/span>: After electroplating, the surface needs to be treated with chemical mechanical planarization (CMP) to remove excess metal and make the substrate surface flat. After that, the relevant protective film needs to be removed. A flat surface is conducive to subsequent circuit connection and packaging processes, just like when building a house, the ground needs to be leveled first.\u00a0<\/span><\/span><\/p>\n

Rewiring and packaging connection\u00a0<\/span><\/span>: Create a redistribution layer (RDL) on the glass substrate to perform circuit layout and pin design for connection with other chips or external packaging components. Then add bumps or other interconnect structures, such as solder balls, to complete the electrical and mechanical connection between chips. This step is like building a transportation network to connect various electronic components and enable them to work together.\u00a0<\/span><\/span><\/p>\n

Glass atomizer cores are developing rapidly. Safety, no harmful substances residue, and uniform heating are its advantages, but oil leakage is a challenge. The solution can be to consider reducing the aperture of the through hole, which requires cooperation with laser through-hole equipment, materials and other links.<\/p>","protected":false},"excerpt":{"rendered":"
