Wafer Expander System is a device used in the semiconductor industry to mechanically stretch the diameter of silicon chips. This process is called wafer expansion or wafer stretching. After the crystal cutting is completed, the spacing is very small and cannot be directly removed from the blue film or UV film. At this point, an wafer expansion machine is needed to increase the wafer size, such as:...

The core purpose of introducing nitrogen (inert gas environment) in the UV curing process is to eliminate the interference of oxygen to the curing reaction, thus significantly improving the curing efficiency, material performance and product yield. The following are the specific reasons and mechanisms of action: 1. Solve the problem of oxygen polymer resistance (Oxygen Inhibition): The free radica...

There are three American EIT energy meters that have undergone the latest calibration by the original factory. One is the POWER PUCK for measuring mercury lamps, one is for measuring 395nm for LEDs, and the other is for measuring the 405nm band. So let's put these three meters in the mercury lamp at the same time, in the same position, for time and speed, and compare the data. As shown in the figu...

1、 Principle of UV glue remover UV glue remover is a fully automated equipment for reducing and releasing the viscosity of UV film and cutting film tape. In the semiconductor chip production process, before chip cutting, the wafer is fixed on the frame with a cutting adhesive film. After the cutting process is completed, the fixing adhesive film is irradiated with UV light to solidify and harden t...

When UV varnish passes through the irradiation area of UVLED curing equipment, the best temperature should be 50-60, because at this temperature, UV varnish cures fast and has strong adhesion after curing.In addition to the choice of UVLED curing equipment affecting UV varnish curing, some varnish itself or operational issues will also have an impact: Scratch resistance: The scratch resistance of ...

Dummy Wafer Dummy means fake, not real. Generally, there are no graphics, or only a few layers of graphics. Main application for: 1.It is used for commissioning and calibration of semiconductor equipment to ensure that the equipment is in the best condition before the official production. 2. When introducing a new process or adjusting an existing process, dummy wafer chips are used for testing and...
