With a total of 5 patents, Hackenberg has made strides in the development of advanced transistor devices that enhance performance and efficiency.

Latest Patents

One of Hackenberg's latest patents is focused on a power trench transistor device source region formation using a silicon spacer. This innovative device features a buried gate to source dielectric within a gate trench region. A thick oxide, either grown or deposited, is utilized to define the height of the trench walls. The body region is initially formed through selective epitaxial growth and etch back, while source regions are also created using selective epitaxial growth. The process culminates in the formation of the body through selective epitaxial growth and etch back. After removing the oxide from the trench, the trench walls are oxidized to create a gate oxide, and doped polysilicon fills the trench to establish a gate. This method simplifies the fabrication of power trench gated devices and increases contact surface area without enlarging the device size.
