Abstract: An interconnect structure on a semiconductor die includes: a lower conductive layer; an upper conductive layer disposed above the lower conductive layer; and a VIA disposed between the lower conductive layer and the upper conductive layer. The VIA includes: a primary interconnect structure and a sacrificial stress barrier ring disposed around the primary interconnect structure and separated a distance from the primary interconnect structure. A fabrication method for the interconnect structure includes: forming a dielectric layer over a lower conductive layer; patterning photoresist (PR) layer over the dielectric layer to define a location for a plurality of VIA trenches, wherein the patterning includes patterning the PR layer to provide a center opening for the VIA trenches that is surrounded by a ring opening for the VIA trenches, wherein the center opening and the ring opening are spaced apart.

Abstract: A method is provided for forming an integrated circuit (IC) chip package structure. The method includes providing a substrate for an interposer, and forming a conductive interconnect structure in and on the substrate for connecting a group of selected IC dies. The method includes forming warpage-reducing trenches in non-routing regions of the interposer, wherein the warpage-reducing trenches are sized and positioned based on a warpage characteristic to reduce the warpage of the chip package structure. The method also includes depositing a warpage-relief material in the warpage-reducing trenches according to the warpage characteristic to reduce the warpage of the chip package structure, and bonding the group of selected IC dies to the interposer to form a chip package structure.

Abstract: A DAC/ADC system for generating reference clocks for DAC/ADC by a look-up table method. The DAC/ADC system includes a sampling signal generator, a DAC, and an ADC. The sampling signal generator generates first and second sampling signals according to first and second reference clocks by a look-up table method, respectively. The DAC receives a digital input signal and converts it into an analog output signal according to the first sampling signal. The ADC receives an analog input signal and converts it into a digital output signal according to the second sampling signal.

Abstract: A helmet has a body, a cover and a chinstrap. The body has a lower segment, an upper segment and an illuminant assembly. The upper segment has multiple locking slots and recesses. The illuminant assembly is mounted in the recesses and has a circuit board, at least one battery seat, multiple illuminants and multiple electrical wires. The cover is mounted detachably on the upper segment of the body and has multiple windows, longitudinal slots and fasteners. The windows are defined through the cover and align respectively with the illuminants. The longitudinal slots are defined through the cover and align respectively with the locking slots. The fasteners detachably mount respectively through the longitudinal slots in the cover and locking slots, and each fastener has a knob and a T-shaped latch. The illuminants are replaced easily by detaching the cover. The chinstrap is attached to the body.
