Abstract
An adaptive patterning method and system for fabricating panel based package structures is described. Misalignment for individual device units in a panel or reticulated wafer may be adjusted for by measuring the position of each individual device unit and forming a unit-specific pattern over each of the respective device units.

An adaptive patterning method comprising:
- measuring a position of each of a plurality of device units of a panel;
- defining a reference position of at least one feature on each of the plurality of device units, wherein the measured position has a different x-y position or orientation as compared to the reference position for the at least one of the plurality of device units;
- creating, by a processor, a unit-specific pattern comprising at least one of a via pattern, a capture pad, and an interconnecting trace pattern, for each of the respective plurality of device units based upon the measured position for each of the respective device units by:
- calculating a delta-value between the measured position and the reference position for each of the respective plurality of device units;
- and
- adjusting a position of the unit-specific pattern by the same delta-value from the reference position of the unit-specific pattern for at least one of the plurality of device units;
- defining a position of the unit-specific pattern over each of the respective device units, wherein the unit-specific pattern created has a different x-y position or orientation as compared to the reference position for each of the respective device units;
- and
- forming the unit-specific patterns over each of the respective device units, wherein each unit-specific pattern is aligned with the respective device unit.
A non-transitory computer-readable storage medium having instructions stored thereon, which, when executed by a processor, cause the processor to perform adaptive patterning operations comprising:
- instructing an inspection tool to measure a position of each of a plurality of device units of a panel;
- defining a reference position of at least one feature on each of the plurality of device units, wherein the measured position has a different x-y position or orientation as compared to the reference position for the at least one of the plurality of device units;
- creating a unit-specific pattern comprising at least one of a first via pattern, a capture pad, and an interconnecting trace pattern, for each of the respective plurality of device units based upon the measured position for each of the respective device units by:
- calculating a delta-value between the measured position and the reference position for each of the respective plurality of device units;
- and
- adjusting a position of the unit-specific pattern by the same delta-value from the reference position of the unit-specific pattern for at least one of the plurality of device units;
- defining a position of the unit-specific pattern over each of the respective device units, wherein the unit-specific pattern created has a different x-y position or orientation as compared to the reference position for each of the respective device units;
- and
- instructing a patterning tool to form the unit-specific patterns over each of the plurality of device units, wherein each unit-specific pattern is aligned with the respective device unit.
An adaptive patterning system comprising:
- an inspection tool to measure a position of a plurality of device units on a panel, and create a file containing the measured position of each of the plurality of device units;
- wherein the inspection tool is configured to define a reference position of at least one feature on each of the plurality of device units, wherein the measured position has a different x-y position or orientation as compared to the reference position for the at least one of the plurality of device units;
- wherein the inspection tool is further configured to create a unit-specific pattern design comprising at least one of a first via pattern, a capture pad and an interconnecting trace pattern, for each of the plurality of device units based upon the measured position of each of the plurality of device units by
- calculating a delta-value between the measured position and the reference position for each of the respective plurality of device units;
- and
- adjusting a position of the unit-specific pattern by the same delta-value from the reference position of the unit-specific pattern for at least one of the plurality of device units;
- wherein the inspection tool is further configured to define a reference position of the unit-specific pattern over each of the respective device units, wherein the unit-specific pattern created has a different x-y position or orientation as compared to the reference position for each of the respective device units;
- and
- a patterning machine to import the unit-specific pattern design and form a patterned feature over each of the plurality of device units.
