SACRIFICIAL SUBSTRATE FOR ETCHING

A method of etching a silicon substrate is described. The method includes bonding a first silicon substrate (200) to a sacrificial silicon substrate (240, 241). The first silicon substrate (200) is etched. A pressure is applied at an interface of the first silicon substrate (200) and the sacrificial...

Zusammenfassung:A method of etching a silicon substrate is described. The method includes bonding a first silicon substrate (200) to a sacrificial silicon substrate (240, 241). The first silicon substrate (200) is etched. A pressure is applied at an interface of the first silicon substrate (200) and the sacrificial silicon substrate (240, 241) to cause the first silicon substrate (200) to separate from the sacrificial silicon substrate (240, 241). An apparatus having metal blades (620) can be used to separate the substrates.
