Via¶
A via is an electrical connection between two different metal layers. SiFab contains two types of metal vias:
VIA_M1_M2¶
It connects M1 and M2.

si_fab.all.VIA_M1_M2 |
Square via from metal layer M1 to metal layer M2. |
Example
from si_fab import all as pdk
# VIA
cell = pdk.VIA_M1_M2()
cell.Layout().visualize(annotate=True)

Contact¶
It connects M1 with the doped Si regions.

si_fab.all.Contact |
Octagonal contact hole to connect metal layer M1 with the (doped) silicon. |
Example
from si_fab import all as pdk
from ipkiss3 import all as i3
# Contact Hole
hole = pdk.Contact()
hole_lv = hole.Layout()
hole_lv.visualize(annotate=True)
class ContactHoleWithP(i3.PCell):
class Layout(i3.LayoutView):
def _generate_instances(self, insts):
insts += i3.SRef(reference=hole)
return insts
def _generate_elements(self, elems):
elems += i3.Rectangle(box_size=(2, 2), layer=i3.TECH.PPLAYER.PPLUS)
return elems
hole_with_p_lv = ContactHoleWithP().Layout()
hole_with_p_lv.visualize_2d()
xs = hole_with_p_lv.cross_section(cross_section_path=i3.Shape([(0.0, -2.0), (0.0, 2.0)]))
xs.visualize()
