# Substrate Map

:lock: SubstrateMap.**Show**

## Overview

A **Substrate Map** is an entity that represents a map of a substrate which can be a wafer, frame, strip or tray in SEMI E142 format (XML and Unit Level).

SEMI E142 is a standard that provides a way to report, store and transmit **Substrate Maps** between semiconductor manufacturing sites by describing the layout of devices on a substrate.

You can have various maps, such as: BinCodeMap, DeviceIdMap, TransferMap, and DeviceDataMap.

![E142 Object Model](images/e142_object-model.png)

This Critical Manufacturing MES feature allows you to visualize an array of `xml` **Substrate Maps** because of the customizations performed on the original SEMI E142 standard. For more information and supported SEMI E142 values, see [CM SEMI E142 schema](cm_semi_e142_schema.md).

!!! info
	  Substrate Maps are part of Mapping, which is a Critical Manufacturing optional module.

To better understand the **Substrate Map** entity, the following concepts and definitions are relevant:

| Concept | Description |
|---------------------------------------|----------------------------------|
| **Axis Direction** (see also **Origin Location**) | Defines in which direction of the axis, X and Y, values increase. These can be Up Right, Down Right, Up Left, and Down Left. The default value is Up Right. |
| **Frame** | A wafer mounted on a film frame so that it may be diced, and the die is picked and placed in a package. |
| **Layout** | The logical and physical dimensions of a two-dimensional array of devices to which a map may be assigned. |
| **Map** | A two-dimensional array of data for a specific layout on a substrate. |
| **Orientation** | The rotation of the substrate (0, 90, 180, or 270 degrees). The default value is 0 degrees. |
| **Origin Location** | Where the (0,0) coordinate is located. It can be Lower Left, Lower Right, Upper Left, Upper Right, or Center. The default value is Lower Left.|
| **Panel** | A rectangular or square substrate on which an array of devices are fabricated. |
| **Strip** | A lead frame, board, or other container on which an array of devices are fabricated. |
| **Substrate** | A surface upon which something is deposited, etched, attached, or otherwise prepared or fabricated. Examples of substrates are wafers, frames, strips, and trays. |
| **Wafer** | A round substrate on which an array of devices are fabricated. |

## System Configurations

The following system configurations, located under `/Cmf/System/Configuration/Mapping/<Key>`, control the behavior of Overlay creation, activation, validation, and historical data storage. These settings allow administrators to define whether activation is handled automatically or by user decision, as well as to balance traceability requirements with performance considerations.

| Key                              | Default Value | Description                                                          |
| -------------------------------- | ------------- | --------------------------------------------------------------------------------------------------------------------------|
| `ActiveBinCodeMapMode`         | `System`      | Determines how the Bin Code Map Overlay becomes active upon creation. If set to `System`, the newly created Overlay automatically becomes the Active version. If set to `User`, you can decide whether to activate the newly created Overlay; otherwise, the previously Active version remains unchanged. |
| `ActiveDeviceIdMapMode`        | `System`      | Determines how the Device ID Map Overlay becomes active upon creation. If set to `System`, the newly created Overlay automatically becomes the Active version. If set to `User`, you can decide whether to activate the newly created Overlay; otherwise, the existing Active version is maintained. |
| `CheckUpdatesAgainstMask`      | `false`       | Specifies whether Map value updates are validated against the defined mask. Enabling this option introduces a significant performance overhead and should only be used when strict validation is required.  |
| `OverlayVersioningMode`        | `System`      | Defines how Overlay version conflicts are handled during insertion. If set to `System`, the Overlay is inserted regardless of existing version numbers. If set to `User`, insertion is allowed only if the version does not already exist.|
| `StoreDeviceBinCodeMapHistory` | `true`        | Indicates whether Device Bin Code Map History data is stored for Substrate Maps. Disabling this option reduces storage usage but removes historical traceability for map changes. |
| `StoreDeviceTraceability`      | `true`        | Indicates whether Device Traceability data is stored for Substrate Maps. Disabling this option reduces storage usage but impacts downstream traceability and audit capabilities. |
