General Requirements

Grid Rules

  • All rules are defined in microns [µm] by default if there is no other unit mentioned

  • All features are on a drawing grid of 5 nm (0.005 µm)

  • Shapes with acute angles <87° are not allowed on any layer

  • Following layers are only allowed on 90, 180 degree angles: Cont, Via1, Via2, Via3, Via4, Vmim, TopVia1, TopVia2

  • Following layers are only allowed on 90, 135, 180, 225, and 270 degree angles: GatPoly, Activ, Metal1, Metal2, Metal3, Metal4, Metal5, TopMetal1, TopMetal2

  • Self-intersecting polygons must be avoided

  • Design elements, which are snapped to grid must not violate any geometries in this document.

There are several layers which are not considered for mask generation. Offgrid and angle checks are not applied on the following layers: DigiBnd, RES, SRAM, IND, EdgeSeal, dfpad, HeatTrans, HeatRes, DigiSub, NoDRC, TEXT, RadHard, Flash, SMOS, Scribe, Recog, NoRCX, NoMetFiller

Forbidden Layers

Following layers are forbidden in designs submitted for all 0.13 µm technologies. Layout data containing these layers will be rejected from the tape-in procedure automatically. Since no waivers are granted, IHP recommends performing the online MPW Rejection Test (https://dk.ihp-microelectronics.com) at an early stage.

Notes

  1. regions are allowed to cross well boundaries in some ESD protection layouts.

  2. Substrate ties for internal logic are required due to p-silicon substrate.

  3. A certain distance between and (see section 4.2) on different nets is required to prevent punchthrough due to different potentials.

Notes

  1. A smaller coverage or larger filler exclusion area leads to smaller metal lines and higher sheet resistance. Sheet resistance of minimum width lines is increasing by 10% if metal coverage is lower than 30%.

  2. must be generated prior to the tape out procedure. For sensitive areas of the circuit, designers should exclude using the or exclusion layer, or should place defined metal structures to prevent metal fill.

Device Layout Rules

Bipolar Design Rules

Bipolar design rules are not disclosed due to IP reasons. Additional layers will be added during the tape out procedure for mask generation. Changing the given layouts may result in catastrophic device malfunction. The IHP library provides a number of predefined devices shown in the follow sections. Do not modify these layouts/abstracts.

Strict design rule: Do not flatten the HBT layout cells and do not place any shapes, except metal for connections, in bipolar regions. Use pins on given metals to connect base, emitter and collector with corresponding metal shapes. Any modification in bipolar transistor results in non-working device.

Device recognition: For device recognition layer in combination with TEXT labels and layer combinations are used for device recognition.

Notes

  1. Iso-PWell-Activ = AND AND

  2. NWell-nBuLay = AND

  3. NWell which is used as a ring for isolated PWell and carries active p-mos devices has to be carefully layed out in order to prevent latch up.

  4. Recommendation: 1 mimimum PWell contact per 50 µm². To calculate voltage drops in PWell consider an average sheet resistance of 3 kΩ.

  5. Recommendation: Use ptapsb Pcell to ensure proper isolated PWell connection. An example can be found in Cadence PDK’s example library.

isolbox

The isolbox structure is used to generate PWell regions isolated from the global substrate. This enables the realization of substrate isolated nmos transistors or resistors. We recommend to use only pcell offered via PDK by IHP. The pins “isosub” and “bn” are not part of the layout pcell and have to be placed manually in order to give designer more flexibility.

Device recognition: isolbox = TEXT “isolbox” within ( enclosed by )

Inductors

In order to verify a custom inductor in the LVS check, additional layers must be added to the actual inductor layout (see Fig. 6.10). The inductor must be completely enclosed by the layer. To define the connection points, rectangles in layer must be placed on the inductor metal. The connection points must touch the edge of the layer and contain a pre-defined text label in layer . These text labels are “LA” and “LB” for inductors with two connections or “LA”, “LB” and “LC” for inductors with three connections.

Parasitic extraction of metal lines is excluded from inductors defined by this procedure. Within this layer there is by default no filler generation.

Following rules will not be checked within this layer: metal slit rules, AFil.g2, MFil.h, TM2.bR

Special Rules

Antenna Rules

The antenna effect occurs when metal layers on a chip are etched during the semiconductor manufacturing process. As the metal layers are etched, the remaining metal traces collect charge during the etching process. When these metal traces discharge, it can lead to damage or unwanted changes in the properties of the connected devices.

The design rules related to unprotected devices are determined by using gate leakage current (shift of 10 % for nominal devices) as failure criterion.

Antenna Rules are not checked by default. Antenna rule checking must be switched on separately.

  2. Vn_area = cumulative area Cont, Via1 to TopVia2

  3. Via_area = cumulative area Via1 to TopVia2

Usage of stacked vias to avoid antenna area ratio violations. Please note that this figure is only an example. The stacked via method can be applied up to .

Recommendations

  • To get DRC clean layouts it is recommended to connect the antenna node to the output of the driver at low metal level to reduce the antenna area or connect the antenna node to a diode.

  • To get DRC clean layouts it is recommended to use stacked vias to connect large metal or via areas as shown in Fig. 7.2.

  • To protect the gate of an isolated nMOS transistors it is recommended to place the antenna-protection diode in a separate (non isolated) p-body region.

  • For applications which are especially sensitive to \(\mathrm{V_t}\) variation or mismatch (sense amplifers, certain analog circuits, etc.), each gate should be tied directly to an nSD/PWell or pSD/NWell diode in Metal1.

Latch-up Guidelines

Latch-up is an undesirable phenomenon in integrated circuit (IC) design that can lead to the inadvertent creation of a low-impedance path between the power supply rails or any other regions forming a parasitic thyristor. The effect is trigged by unwated injection of charges into this structure. This can lead to destruction of circuit parts due to overcurrent.

Latch-up rules are not checked by default. Latch-up rule checking must be switched on separately.

Latch-up Protection on Output Buffers

  1. Connect source of NMOS and PMOS devices to VSS and VDD, respectively.

  2. Connect drain of NMOS and PMOS devices directly to the output pad.

  3. Place guard rings (VSS, VDD ties) around any NMOS and PMOS devices, which are directly tied to a pad.

  4. Double guard rings (N-Well isolator and P+ isolator) should be inserted between n-channel and p- channel output buffers.

  5. Double guard rings (N-Well isolator and P+ isolator) should be inserted between output buffers and internal circuit area.

Pin Layer Rules

Circuit designers should use only drawing purpose 0 (data types) for layouts. Only exception is pin purpose 2 for symbolic pins. Data type 2 (purpose pin) is used for symbolic connectivity information. Pin areas must be fully covered by drawing. These rules are tested because pin areas are not used for mask generation and a potential issue due to false postive LVS matchs.
