摘要： A semiconductor package is assembled using first and second lead frames. The first lead frame includes a die flag and the second lead frame includes lead fingers. When the first and second lead frames are mated, the lead fingers surround the die flag. Side surfaces of the die flag are partially etched to form an extended die attach surface on the die flag, and portions of the top surface of each of the lead fingers also are partially etched to form lead finger surfaces that are complementary with the etched side surfaces of the die flag. A semiconductor die is attached to the extended die attach surface and bond pads of the semiconductor die are electrically connected to the lead fingers. An encapsulating material covers the die, electrical connections, and top surfaces of the die flag and lead fingers.

摘要： Methods for calibrating a photolithographic system are disclosed. A cold lens contour for a reticle design and at least one hot lens contour for the reticle design are generated from which a process window is defined. Aberrations induced by a lens manipulator are characterized in a manipulator model and the process window is optimized using the manipulator model. Aberrations are characterized by identifying variations in critical dimensions caused by lens manipulation for a plurality of manipulator settings and by modeling behavior of the manipulator as a relationship between manipulator settings and aberrations. The process window may be optimized by minimizing a cost function for a set of critical locations.

摘要： A real-time, signature-free, blocker prevents buffer overflow attacks. The system and method, called SigFree, can filter out code injection buffer overflow attack packets targeting at various Internet services such as web services. Motivated by the observation that buffer overflow attacks typically contain executables whereas legitimate client requests never contain executables in most Internet services, SigFree blocks attacks by checking, without any preknowledge of the real attacks, if “executable” instruction sequences can be blindly disassembled and extracted from a packet. Being signature-free, the invention can block new and unknown buffer overflow attacks. It is immunized from almost every attack-side code obfuscation method, and transparent to the servers being protected. The approach is therefore suited to economical Internet-wide deployment with very low deployment and maintenance costs. SigFree can also handle encrypted SSL packets. An experimental study shows that SigFree can block all types of code-injection attack packets without yielding any false positives or false negatives. Moreover, SigFree causes negligible throughput degradation to normal client requests.

摘要： A receiver supports a single carrier (SC) form of modulation and a multi-carrier form of modulation such as orthogonal frequency division multiplexing (OFDM). Upon receiving a signal, the receiver determines a maximum fluctuation range (MFR) as a function of at least a fourth-order cumulant of a received signal; and classifies a modulation type of the received signal as a function of the determined maximum fluctuation range. After determining the modulation type of the received signal, the receiver switches to that modulation mode to recover data from the received signal.
