  • Formation of a slot in a silicon substrate
    Patent number: 7855151
    Abstract: A slot is formed that reaches through a first side of a silicon substrate to a second side of the silicon substrate. A trench is laser patterned. The trench has a mouth at the first side of the silicon substrate. The trench does not reach the second side of the silicon substrate. The trench is dry etched until a depth of at least a portion of the trench is extended approximately to the second side of the silicon substrate (12). A wet etch is performed to complete formation of the slot. The wet etch etches silicon from all surfaces of the trench.
