Title: gate geometry
Post by: Kengo on November 17, 2016, 06:24

Hi

I have a question about gate geometry.
Can I make triangle-shape gate or rectangle shape in any angle(for example 45 degree from Z axis)?

Thanks in advance

Regards,

You can only make Box, Tube and Sphere shaped spacial regions for dielectric spacers and metal gate electrodes. Of course, you may try making a triangle spacial region by filling it up with smaller box-shaped regions.  Just for me to understand, why do you actually need a triangle-shaped gate electrode? Are they really used in real device setups?

Dear Petr Khomyakov

That's because some experiments use triangle-shaped gate.
I want to calculate the structure like following paper.
