Summary: | A method of etching a silicon substrate is described. The method includes bonding a first silicon substrate to a sacrificial silicon substrate. The first silicon substrate is etched. A pressure is applied at an interface of the first silicon substrate and the sacrificial silicon substrate to cause the first silicon substrate to separate from the sacrificial silicon substrate. An apparatus having metal blades can be used to separate the substrates. |
