1. A method of fabricating a die containing an integrated circuit comprising active components and passive components, at least a part of the passive components comprising critical passive components, the method comprising:
- producing a first substrate including at least one active component including heating the first substrate at a temperature lower than a first temperature above which the first substrate is unacceptably degraded;
producing a second substrate including the critical passive components including heating the second substrate at a temperature higher than the first temperature;
bonding the first and second substrates, wherein the bonding comprises performing a layer transfer; and
after bonding of the first and second substrates, producing at least one interconnection line between the components of the first and second substrates, the interconnection line passing through the second substrate.

Abstract
A method of fabricating a die containing an integrated circuit, including active components and passive components, includes producing a first substrate containing at least one active component of active components and a second substrate containing critical components of the passive components, such as perovskites or MEMS, and bonding the two substrates by a layer transfer. The method provides an improved monolithic integration of devices such as MEMS with transistors.

15. A die made of a single stack of layers, containing an integrated circuit comprising active components produced at a temperature lower than a first temperature above which the active components are unacceptably degraded and comprising passive components,
wherein at least a part of the passive components comprising critical passive components produced at a temperature higher than the first temperature above which the active components are unacceptably degraded, wherein the die comprises an interface between two of the layers such that a first portion of the die situated on one side of the interface includes the active component and a second portion of the die situated on the other side of the interface includes the critical passive components produced at the temperature higher than the first temperature, wherein the die comprises at least one interconnection line between the components of the first and second portions, the interconnection line passing through the second portion of the die.
