Technical FAQs 4

What is glass bonding?

Glass bonding is defined as the process of joining glass substrates through various techniques, such as anodic bonding, surface activated bonding, fusion bonding, adhesive bonding, and laser welding, each involving specific conditions and methods to achieve desired bond strength and integrity. How useful is this definition?

Why do solar cells need a cover glass?

4. Loss analysis and pathway to higher performance With anodic bonding of the GaAs solar cell to the cover glass, the glass can serve as a mechanical superstrate, enabling the removal of the growth substrate while also offering radiation shielding.

How do ions bond to glass?

Positive ions diffusing away from the bonding interface generate free NBO anions that bond chemically with silicon, forming Si–O–Si covalent bonds . It should be noted that, to bond glass to any other material by anodic bonding, the glass should contain NBO anions (and hence mobile ions).

How is GaAs bonded to borosilicate glass?

The front surface of the GaAs contact layer was directly bonded to borosilicate glass. The GaAs wafer and glass stack, with the graphite paper to absorb the sodium generated during the bonding, is clamped by upper and lower tungsten platens in a wafer bonder tool (Applied Microengineering AWB-04), as shown in Fig. 1 (a).
