Abstract
A system for injecting faults by laser beams into an electronic circuit including: at least two lasers capable of emitting approximately parallel beams; at least one optical system receiving, on the magnifying side, the beams; and a support of the integrated circuit placed on the reducing side of the optical system.
Claims16
A system for injecting faults by laser beams into an electronic circuit, the system comprising:
- at least two lasers configured to emit approximately parallel first and second beams;
- at least two optical systems having a magnifying side and a reducing side in a reverse telescoping arrangement;
- and
- an electronic circuit disposed on the reducing side of the at least two optical systems, wherein the at least two optical systems are configured to apply said first and second beams, respectively, to first and second surfaces, respectively, of the electronic circuit,
- wherein the magnifying side of the at least two optical systems is configured to receive one of said first and second beams, and wherein one of the at least two optical systems is configured to apply, via the reducing side, the first beams to the first surface of the electronic circuit with an orientation orthogonal to the surface of the electronic circuit and the other of the two optical systems is configured to apply, via the reducing side, the second beam to the second surface of the electronic circuit with an orientation orthogonal to the surface of the electronic circuit.

A method comprising:
- using first and second option systems to reduce optical beams, the first and second optical systems having a magnifying side and a reducing side in a reverse telescoping arrangement, the optical beams including a first optical beam and a second optical beam, the first optical beam being approximately parallel to the second optical beam at an input of the optical systems and at an output of the optical systems;
- applying, via the output of the first optical system, the first optical beam to a first surface of an integrated circuit at an angle of incidence orthogonal to the first surface of the integrated circuit;
- and
- applying, via the output of the second optical system, the second optical beam to a second surface of the integrated circuit at an angle of incidence orthogonal to the second surface of the integrated circuit, the second surface being opposite the first surface.
