Claim Text:
1. A super junction trench power metal oxide semiconductor field effect transistor (MOSFET) device having a channel of first type dopant, said device comprising: a first column comprising insulating material that separates a column of second type dopant from a first column of said first type dopant; a second column comprising insulating material that separates said column of said second type dopant from a second column of said first type dopant; a gate element for a field effect transistor, wherein said gate element is aligned between said first column of insulating material and said second column of insulating material and is positioned above said column of said second type dopant; and a trench formed between said gate element and an adjacent gate element, said trench extending into said first column of said first type dopant, said trench filled with source metal.
