Systems and methods are disclosed herein for determining the placement of storage and non-storage cells or components, representing a semiconductor component in a design stage, on an integrated circuit die. In one embodiment, regions of a semiconductor die are analyzed with respect to the susceptibility of a region to be exposed to radiation and the distance between a storage component and a local clock buffer. The radiation, for instance, may be alpha particle radiation emitted from lead (Pb) isotopes in solder bumps formed on the integrated circuit die. The distance, spatial positioning and/or physical proximity of a selected local clock buffer and a storage component are preferably selected so that the skew between the storage component and the local clock buffer is about 30 picoseconds or less. Other maximum skews may be employed, however, such as about 100 picoseconds or less, about 90 picoseconds or less, about 80 picoseconds or less, about 70 picoseconds or less, about 60 picoseconds or less, about 50 picoseconds or less, about 40 picoseconds or less, about 20 picoseconds or less, about 10 picoseconds or less and about 5 picoseconds or less.

A structure and a method for reduction of soft error rates in integrated circuits. The structure including: a semiconductor substrate; and a stack of one or more wiring levels stacked from a lowermost wiring level to an uppermost wiring level, the lowermost wiring level nearer the semiconductor substrate than the uppermost wiring level; and an alpha particle blocking layer on a top surface of the uppermost wiring level of the one or more wiring levels, the blocking layer comprising metal wires and a dielectric material, the blocking layer having a combination of a thickness of the blocking layer and a volume percent of metal wires in the blocking layer sufficient to stop a predetermined percentage of alpha particles of a selected energy or less striking the blocking layer from penetrating into the stack of one or more wiring levels or the substrate.

A composite transistor is disclosed for use in radiation hardening a CMOS IC formed on an SOI or bulk semiconductor substrate. The composite transistor has a circuit transistor and a blocking transistor connected in series with a common gate connection. A body terminal of the blocking transistor is connected only to a source terminal thereof, and to no other connection point. The blocking transistor acts to prevent a single-event transient (SET) occurring in the circuit transistor from being coupled outside the composite transistor. Similarly, when a SET occurs in the blocking transistor, the circuit transistor prevents the SET from being coupled outside the composite transistor. N-type and P-type composite transistors can be used for each and every transistor in the CMOS IC to radiation harden the IC, and can be used to form inverters and transmission gates which are the building blocks of CMOS ICs.

A method and system are provided for accelerated detection of soft error rates (SER) in integrated circuits (IC's) due to transient particle emission. An integrated circuit is packaged for accelerated transient particle emission by doping the underfill thereof with a transient-particle-emitting material having a predetermined emission rate. The emission rate is substantially constant over a predetermined period of time for testing. Accelerated transient-particle-emission testing is performed on the integrated circuit. Single-event upsets due to soft errors are detected, and a quantitative measurement of SER is determined.
