Abstract
An assembly includes an integrated circuit, a film layer disposed over the integrated circuit and having a thickness of at least 50 microns, and a thermal neutron absorber layer comprising at least 0.5% thermal neutron absorber. The thermal neutron absorber layer can be a glass layer or can include a molding compound.
Claims21
An apparatus comprising:
- an integrated circuit;
- one or more layers disposed over the integrated circuit;
- and
- a thermal neutron absorber layer, disposed over the one or more layers, comprising thermal neutron absorbing material wherein a combined thickness of the one or more layers is at least 50 microns so as to decrease an effect on the integrated circuit by a particle emitted from the thermal neutron absorber layer.
The apparatus of claim wherein the one or more layers comprises at least one of polyester, polyamide, polyphenylene sulfide, polyphenylene oxide, silicone, phenolic resin, epoxy, acrylate, acrylonitrile-butadiene copolymer, polyimide, polyurethane, and polyolefin, or a combination thereof.
A method comprising:
- dispensing an integrated circuit;
- depositing one or more layers over the integrated circuit;
- and
- placing a thermal neutron absorber layer over the one or more layers, the thermal neutron absorber layer having thermal neutron absorbing material, wherein a combined thickness of the one or more layers is at least 50 microns so as to decrease an effect on the integrated circuit by a particle emitted from the thermal neutron absorber layer.
An apparatus comprising:
- an integrated circuit;
- one or more layers disposed over the integrated circuit;
- and
- a thermal neutron absorber glass layer, disposed over the one or more layers, comprising thermal neutron absorbing material, wherein a combined thickness of one or more layers is at least 50 microns so as to decrease an effect integrated circuit by a particle emitted from the thermal neutron absorber layer.
