摘要: Methods of fabricating a super junction trench power MOSFET (metal oxide semiconductor field effect transistor) device are described. A column of p-type dopant in the super junction is separated from a first column of n-type dopant by a first column of oxide and from a second column of n-type dopant by a second column of oxide. In an n-channel device, a gate element for the FET is advantageously situated over the column of p-type dopant; and in a p-channel device, a gate element for the FET is advantageously situated over the column of n-type dopant.

摘要: A split gate semiconductor device includes a trench gate having a first electrode region and a second electrode region that are separated from each other by a gate oxide layer and an adjacent dielectric layer. The boundary of the gate oxide layer and the dielectric layer is curved to avoid a sharp corner where the gate oxide layer meets the sidewalls of the trench.
