Comprehension Semiconductor Wafer Probing: Tactics, Difficulties, and Potential Perspectives
1. Introduction to Semiconductor Wafer Probing
Semiconductor wafer probing is an essential stage in the semiconductor producing course of action. It is a tests strategy applied To guage the electrical performance of the semiconductor wafer, ordinarily employing a probe card to make a short term electrical connection between the testing machines and the device underneath examination.
2. The Process of Semiconductor Wafer Probing
Semiconductor wafer probing can be executed manually or immediately, depending upon the complexity and prerequisites of your undertaking.
Handbook Probing
In guide probing, a technician manually positions the probe needles above particular factors around the wafer. This process provides flexibility but is frequently time-consuming and liable to human error.
Automatic Probing
Automated probing requires the use of specialized gear to posture the probe needles correctly. This method is quicker and even more reputable than manual probing and is particularly progressively chosen for high-volume screening.
