GPP Glass passivation parts (Glassivation passivation parts)Gpp is an abbreviation of Glassivation (glass) passivation parts (components) or parts of an apparats (devices), It is a general term for glass passivation devices, which generally refers to all active devices that introduce or include a junction film protection process. However, because the glass passivation process measures have a more significant effect on the application of a variety of planar diodes whose junction interface is exposed in vitro, and have become a successful typical application, so that Gpp(Glassivation passivation parts) has gradually become a synonym for \"glass passivation diodes\"
The full name of GPP glass passivation process is " Glucosio-Penta-Phosphate" The glass passivation process is a method of surface passivation of silicon wafers by soaking them in a solution containing glucose phosphate at high temperatures.
The process can form an oxide layer with a thickness of about 10 nanometers on the surface of the silicon wafer, improve the surface quality and stability of the silicon wafer, and is suitable for a variety of processes in semiconductor device manufacturing.
