  • Publication number: 20240027331
    Abstract: A hand-held scanning probe is included in an optical scanning system. The hand-held scanning probe includes a housing and an optical component. The optical component includes a first lens, a reflector, a two-dimensional beam scanning mechanism, a splitter and a second lens. The first lens is used to receive a laser beam split by a fiber-coupled splitter and convert the laser beam into a form of collimated light. The reflector is used to refract the laser beam. The two-dimensional beam scanning mechanism provides the laser beam to a surface for two-dimensional scanning, producing a swing beam. The splitter is used to separate a scanning end beam returned from the test specimen from an illumination beam into two different light paths. The second lens is used to focus the swing beam at the test surface to form the scanning end beam for scanning. An optical scanning system is also provided.

  • Publication number: 20240030215
    Abstract: The ability of a grounded gate NMOS (ggNMOS) device to withstand and protect against human body model (HBM) electrostatic discharge (ESD) events is greatly increased by resistance balancing straps. The resistance balancing straps are areas of high resistance formed in the substrate between an active area that includes a MOSFET of the ggNMOS device and a bulk ring that surrounds the active area. A Vss rail is coupled to the substrate beneath the MOSFET through the bulk ring. The substrate beneath the MOSFET provides base regions for parasitic transistors that switch on for the ggNMOS device to operate. The straps inhibit low resistance pathways between the base regions and the bulk ring and prevent a large portion of the ggNMOS device from being switched off while a remaining portion of the ggNMOS device remains switched on. The strap may be divided into segments inserted at strategic locations.

  • Publication number: 20240021558
    Abstract: A chip structure has a chip body having a plurality of pads, a plurality of metal bumps respectively formed on the pads, and a patterned bump directly formed on the chip body. The patterned bump has at least two different upper and lower plane patterns. A top surface of each of the metal bumps is higher than a height position on which the upper plane pattern is. When the chip structure is ground to the height position, the ground tops of the metal bumps and the upper plane pattern are flush. Therefore, detecting whether the upper plane pattern is exposed determines whether all the metal bumps are exposed and flush to each other to avoid insufficient grinding depth or over-ground.
