摘要
We report on using a single trench unit process for the trench isolation and for the trench power MOSFET of a common-drain smart power IC technology. The trench power MOSFET has a maximum specific on-resistance, (R-on.A), below 50m Omega-mm(2) and a typical breakdown voltage, V-br, of 95V. The trench isolation provides well isolation up to 90V. Using a single trench unit process for both devices results in low process costs. In addition both power and logic areas of a chip benefit from the trench process.
