    摘要: An integrated circuit (IC) device package includes an IC device connected to an upper surface of the IC device carrier. Due to operation conditions or IC device package makeup, the IC device may warp. The warped IC device may include a convex upper surface. A conformable lid is connected to the IC device and includes an internal chamber and a deformable floor. The deformable floor is able to deform or bend along with the IC device. After deformation, the deformable floor may include a concave lower surface. A uniform bond line thickness of a thermal interface material that connects the IC device and the conformable lid is able to be achieved due to the deformable floor deforming or bending along with the IC device.

    摘要: An optical electromagnetic radiation (EM) emitter and receiver are located upon a printed circuit board (PCB) glass security layer. A predetermined reference flux or interference pattern, respectively, is an expected flux or reflection pattern of EM emitted from the EM emitter, transmitted by the glass security layer, and received by the EM receiver. When the PCB is subject to an unauthorized access thereof the optical EM transmitted by glass security layer is altered. An optical monitoring device that monitors the flux or interference pattern of the optical EM received by the EM receiver detects a change in flux or interference pattern, in relation to the reference flux or reference interference pattern, respectively, and passes a tamper signal to one or more computer system devices to respond to the unauthorized access. For example, one or more cryptographic adapter card or computer system functions or secured crypto components may be disabled.

    摘要: A heat sink includes a first fin and a second fin. The spacing between the first fin and the second fin may be adjusted by a threaded rod. The threaded rod may include a first portion that is engaged with the first fin and a second portion that is engaged with the second fin. The thread pitch of the first portion and the second portion may differ. For example, the pitch of a first internal thread of the first fin may be smaller than the pitch of a second internal thread of the second fin. The spacing of the heat sink fins may be adjusted based upon the current operating conditions of the electronic device to maintain an optimal temperature of a heat generating device during device operation.

    摘要: An integrated circuit (IC) device, such as a wafer, die, or the like, includes a viscoelastic pad upon a contact. The viscoelastic pad includes a viscoelastic material and an electrically conductive material within the viscoelastic material. The viscoelastic pad provides for a probe needle of an IC device tester to be electrically connected to the IC device contact without the probe needle directly contacting the IC device contact. The viscoelastic pad may be probed multiple instances by the probe needle and may be washed or otherwise removed from the IC device after testing is completed. The viscoelastic pad may be formed upon the IC device by forming the viscoelastic material within a mask, aligning the viscoelastic pad to the IC device contact, and ejecting the viscoelastic material from the mask upon the IC device contact.

    摘要: A graded cap is formed upon an interconnect, such as a back end of line wire. The graded cap includes a microstructure that uniformly changes from a metal nearest the interconnect to a metal nitride most distal from the interconnect. The graded cap is formed by nitriding a metal cap that is formed upon the interconnect. During nitriding an exposed one or more perimeter portions of the metal cap become a metal nitride with a larger amount or concentration of Nitrogen while one or more inner portions of the metal cap nearest the interconnect may be maintained as the metal or become the metal nitride with a fewer amount or concentration of Nitrogen. The resulting graded cap includes a gradually or uniformly changing microstructure between the one or more inner portions and the one or more perimeter portions.

    摘要: An integrated circuit (IC) chip carrier includes an IC chip electrically connected to an IC chip carrier by a plurality of chip-carrier contacts, a cover thermally connected the IC chip upper surface, and an in-plane thermal conductance (ITC) layer upon the IC chip carrier between the IC chip carrier and the IC chip. The ITC layer includes an extension tab connected to a vertical side surface of the cover. Heat is transferred vertically from the IC chip to the cover. Heat is also transferred vertically from the IC chip to the ITC layer. Heat is also transferred within the ITC layer through the ITC layer basal plane(s). The ITC layer basal plane(s) are positioned horizontally where the ITC layer is between the IC chip and the IC chip carrier. The ITC layer basal planes are positioned vertically where the extension tab contacts the vertical side surface of the cover.
