What Are the Applications of Tungsten Wire in Computer Chips?

Tungsten wire is not typically used directly in computer chips as a building material for electronic components, but tungsten plays an important role in the computer chip manufacturing process. The following are the main applications of tungsten in computer chip manufacturing:

Semiconductor Manufacturing: Tungsten is used in semiconductor manufacturing to make semiconductor devices such as transistors, capacitors, and resistors. Especially in modern integrated circuits where the size is reduced to the nanometer level, microfabrication technology is required. Tungsten can be used to make electrodes, leads and other tiny components to ensure their performance stability and reliability.

Photolithography Process: In the semiconductor industry, tungsten is also used in photolithography processes. In this process, photoresist is projected onto a silicon wafer and then exposed via UV or other light sources. Tungsten is used to make masks, which are thin films used to create the desired patterns for patterning on silicon wafers.

Packaging and packaging materials: In the chip packaging process, tungsten metal is used as packaging and connecting materials. Its high melting point and conductive properties make it a suitable material for connecting chips to external circuits.

Thermal Materials: Thermal management is an important issue in high-performance computers and servers. Tungsten alloys can be used in heat sinks, heat sink substrates and other heat dissipation components to help control the temperature of computer chips and ensure their normal operation.

X-ray substrate: Tungsten can also be used as an X-ray substrate material for the preparation of X-ray perspective image sensors. This has important applications in areas such as medical imaging, security inspections and industrial inspection.
