Description

Carrier device capable of detecting light-emitting element

The invention relates to a detection device, in particular to a carrier device capable of detecting light-emitting elements.

As the development of integrated circuits tends to be miniaturized, the volume of integrated circuits has been made smaller and smaller. At present, the volume of semiconductors has been gradually reduced to 5 nanometers (nm), and even research and development of 3 nanometer processes are in progress. In other words, as the grains get smaller and smaller, the grain detection becomes relatively more difficult.

In the inspection of crystal grains, in addition to detecting whether the surface of the crystal grain is worn or defective, it is also necessary to detect whether the crystal grain can be used. The probe contacts the light-emitting diode die to provide light-emitting diode power, thereby determining whether the light-emitting diode die can emit light by the power.

However, as the grains are gradually made smaller, the following two problems are prone to occur when using probes for grain detection: 1. The crystal size of the light-emitting diode grains is currently less than 10um, This size has reached the physical limit of the probe. Although the probe can reach 1um, it is very easy to damage, difficult to control, and the measurement variation is large; 2. Due to the miniaturization of the grain, the number of grains on the wafer can be generated more The more it comes, the more the grains detected by the probe become more, and the alignment and detection speed are slower. Of course, the degree of wear becomes relatively faster, which shortens the service life of the probe.
