The tip geometry of tungsten needles can have a significant effect on their ability to produce specific shapes in microfabrication. The shape of the tip can determine the resolution and accuracy of the pattern produced. For example, a conical tip may produce a wider pattern, while a sharp tip may produce a narrower pattern. The angle of the tip can also affect the pattern produced, with sharper angles producing more precise patterns. Additionally, the length of the tip can affect the depth of the pattern produced. Overall, the tip geometry of tungsten needles should be carefully chosen based on the specific needs of the microfabrication application.
