Title: Innovations of Raj Pendse
Introduction
Raj Pendse is an accomplished inventor based in Fremont, CA. He has made significant contributions to the field of semiconductor technology, holding a total of 2 patents. His work focuses on enhancing the precision and efficiency of semiconductor chip bonding processes.
Latest Patents
Raj Pendse's latest patents include a method for creating a precisely aligned lead frame using registration traces and pads. This innovation involves the assembly of aligned tape automated bonding frames on a substrate. The method consists of photolithographically patterning and etching metal to form a first pattern of signal leads and a second pattern of alignment leads. A semiconductor chip is bonded to the inner lead ends of the first pattern. Additionally, metal on a substrate is photolithographically patterned and etched to provide a third pattern of substrate connection sites and a fourth pattern of registration pads. The fourth pattern of registration pads has geometric and dimensional features that correspond precisely to those of the alignment leads. The spatial relationship of the third and fourth patterns corresponds to that of the first and second patterns. The corresponding geometric and dimensional features of the second and fourth patterns are aligned, after which the registration pads and alignment leads are soldered together. This attachment provides fixed registration of the first and third patterns. The substrate is designed to include redundant registration pads to facilitate the replacement of a defective semiconductor chip.
