Rib PIN doped cross_section.
- Parameters:
width – ridge width.
layer – ridge layer.
layer_slab – slab layer.
layers_via_stack1 – list of bot layer.
layers_via_stack2 – list of top layer.
bbox_offsets_via_stack1 – for bot.
bbox_offsets_via_stack2 – for top.
via_stack_width – in um.
via_stack_gap – offset from via_stack to ridge edge.
slab_gap – extra slab gap (negative: via_stack goes beyond slab).
layer_via – for via.
via_width – in um.
via_offsets – in um.
sections – cross_section sections.
kwargs – cross_section settings.
