摘要:
A method for accessing a portion of an integrated circuit formed on top of a semiconductor substrate from the bottom of the semiconductor substrate. First, alignment marks are located which are approximately aligned to the integrated circuit. These alignment marks are then used in conjunction with a circuit diagram of the integrated circuit to determine the point on the bottom of the semiconductor substrate residing beneath the portion of the integrated circuit which the practitioner desires to access. Finally, an opening is etched into the bottom of the semiconductor substrate at this point.

A backside interconnect structure is used to deliver power through the substrate to the front side of an integrated circuit. One or more power planes are formed on the backside of the substrate and coupled to power nodes on the front side by deep vias in the substrate. In a specific embodiment of the invention, power planes are coupled through the substrate to front side metal lines, well taps and external connection points. Placing power planes on the opposite side of the substrate from the signal interconnects allows the use of low dielectric constant materials between signal lines, while using high dielectric constant materials between power planes thus increasing decoupling capacitance without increasing parasitic capacitance between signal lines.

A method and apparatus for controlling the removal of material from a semiconductor substrate in an integrated circuit fabrication process is disclosed. The method and apparatus utilize a light source or charged particle beam (electron or ion beam) to induce a current in at least one P-N junction formed in the semiconductor substrate. The induced current is monitored during the removal of material and the process is stopped or endpointed in response to the induced current making a predetermined transition.

摘要:
A method and an apparatus providing a mechanical probe structure through the back side of an integrated circuit die. In one embodiment, semiconductor substrate is thinned from the back side of the integrated circuit die above a probe target. The probe target is then exposed and a thin insulating layer is formed over the exposed probe target and the nearby semiconductor substrate. The thin insulating layer provides electrical isolation between the exposed probe target and the bulk semiconductor substrate. The thin insulating layer also provides a base insulating platform for a probe pad that is subsequently deposited. After the insulating layer is formed over the exposed probe target and the nearby semiconductor substrate, the probe target is re-exposed through insulating layer such that a probe pad may be deposited over the probe target to provide electrical contact to the original probe target as well as provide a probe pad for mechanical probing purposes from the back side of the integrated circuit die.
