Technology

The ihp.tech module defines the IHP SG13G2 130nm BiCMOS process technology for use with GDSFactory. It is exposed at the top level as ihp.tech and its key objects are re-exported by the PDK:

from ihp import LAYER, LAYER_STACK, LAYER_VIEWS, cross_sections
# or equivalently:
from ihp.tech import LAYER, LAYER_STACK, TECH

Layer Map

LAYER is an instance of LayerMapIHP, a Pydantic model mapping every IHP SG13G2 GDS layer to its (layer, datatype) tuple. Access layers as attributes:

from ihp.tech import LAYER

LAYER.Metal1drawing   # (8, 0)
LAYER.TopMetal2drawing # (134, 0)
LAYER.Activdrawing     # (1, 0)

class ihp.tech.LayerMapIHP(value=<no_arg>, names=None, module=None, qualname=None, type=None, start=1, boundary=None)

Layer Stack

LAYER_STACK provides a 3D representation of the metal/via stack for cross-sectional visualization and electromagnetic simulation (e.g. with Palace or MEEP). Thicknesses follow the IHP SG13 process specifications.

The stack includes: substrate, active silicon, poly gate, Metal1–Metal5, Via1–Via4, TopVia1, TopMetal1, TopVia2, and TopMetal2.

ihp.tech.get_layer_stack(thickness_gatpoly=0.16, thickness_cont=0.64, thickness_metal1=0.42, thickness_metal=0.49, thickness_via=0.54, thickness_topvia1=0.85, thickness_topmetal1=2.0, thickness_topvia2=2.8, thickness_topmetal2=3.0)

Returns IHP PDK LayerStack for 3D visualization and simulation.

Layer thicknesses are based on the IHP SG13 process specifications. Reference: https://ihp-open-pdk-docs.readthedocs.io/en/latest/process_specs/01_01_main_process_cross_sec.html

Parameters:

• thickness_gatepoly – Gate Oxide thickness in um (default: 0.16)

• thickness_cont (float) – Activ-Metal1 Cont thickness in um (default: 0.64)

• thickness_metal1 (float) – Metal1 layer thickness in um (default: 0.42).

• thickness_metal (float) – Metal2-5 layer thickness in um (default: 0.49).

• thickness_via (float) – Via1-4 layer thickness in um (default: 0.54).

• thickness_topvia1 (float) – TopVia1 layer thickness in um (default: 0.85).

• thickness_topmetal1 (float) – TopMetal1 layer thickness in um (default: 2.0).

• thickness_topvia2 (float) – TopVia2 layer thickness in um (default: 2.8).

• thickness_topmetal2 (float) – TopMetal2 layer thickness in um (default: 3.0).

• thickness_gatpoly (float)

Returns:

LayerStack for IHP PDK with properly connected metal and via layers.

Return type:

LayerStack

Cross-Sections

Pre-defined cross-sections for electrical routing on each metal layer. All cross-sections use port_type="electrical".

Name	Layer	Default Width
metal1_routing	Metal1drawing (8, 0)	0.28 um
metal2_routing	Metal2drawing (10, 0)	0.32 um
metal3_routing	Metal3drawing (30, 0)	0.40 um
topmetal1_routing	TopMetal1drawing (126, 0)	1.0 um
topmetal2_routing	TopMetal2drawing (134, 0)	2.0 um

strip and metal_routing are aliases for topmetal2_routing.

ihp.tech.metal_routing(*, width=2.0, layer=<LayerMapIHP.TopMetal2drawing: 354>, radius=None, port_names=('e1', 'e2'), port_types=('electrical', 'electrical'), **kwargs)

Return Metal Strip cross_section.

Parameters:

• width (float)

• layer (tuple[int, int] | str | int | LayerEnum)

• radius (float | None)

• port_names (tuple[str, str])

• port_types (tuple[str, str])

• kwargs (Any)

Return type:

Routing Strategies

The PDK registers these routing strategies for use with GDSFactory’s auto-routing:

Strategy	Description
route_bundle	Bundle routing with strip (TopMetal2) cross-section
route_bundle_rib	Bundle routing with rib cross-section
route_bundle_metal	Metal bundle routing with bends (bend_metal)
route_bundle_metal_corner	Metal bundle routing with 90-degree corners (wire_corner)
route_astar	A* pathfinding on TopMetal2 with euler bends
route_astar_metal	A* pathfinding on TopMetal2 with wire corners

Connectivity

The PDK defines layer connectivity for LVS and routing:

Metal1  -- Via1    -- Metal2
Metal2  -- Via2    -- Metal3
Metal3  -- Via3    -- Metal4
Metal4  -- Via4    -- Metal5
Metal5  -- TopVia1 -- TopMetal1
TopMetal1 -- TopVia2 -- TopMetal2
