a method is provided for anodically bonding glass and semiconducting material . a glass sample is immersed in a molten salt bath for a fixed period of time to modify the surface of the glass sample via ion exchange . the salt is a lithium salt or a proton source . after the glass sample is removed from the salt bath , the glass sample and semiconducting material are placed onto one another , and are then heated to a temperature of between 100 ° c . and 500 ° c . while at this temperature , a potential is applied across the glass and semiconducting material for a fixed period of time to effect anodic bonding together of the glass and semiconducting material .
