  • Publication number: 20240145217
    Abstract: Methods for processing a dielectric film to improve its uniformity of thickness and refractive index are disclosed. The dielectric film is deposited using conventional approaches, such as chemical vapor deposition (CVD) or spin coating. The workpiece, with the applied dielectric film is then processed to improve the uniformity of the thickness. This processing may comprise implanting a thinning species to the thicker portions of the dielectric film to reduce the thickness of these portions. The thinning species may be silicon or another suitable species. This processing may alternatively or additionally include implanting a thickening species to the thinner portions of the dielectric film to increase their thickness. The thickening species may be helium or another suitable species. This approach may reduce the variation in thickness by 50% or more.

  • Publication number: 20240126180
    Abstract: Embodiments of the present disclosure relate to a system, a software application, and methods of digital lithography for semiconductor packaging. The method includes comparing positions of vias and via locations, generating position data based on the comparing the positions of vias and the via locations, providing the position data of the vias to a digital lithography device, updating a redistributed metal layer (RDL) mask pattern according to the position data such that RDL locations correspond to the positions of the vias, and projecting the RDL mask pattern with the digital lithography device.

  • Patent number: 10620603
    Abstract: A method for monitoring operational conditions of an HVAC unit and providing preventive maintenance alerts and/or troubleshooting instructions using an ordered set of causes for sensed parameters by monitoring parameters of the HVAC unit with sensors, collecting real time information and transmitting the data and analyzing the data with a processor and comparing it to a list of pre-determined data set points to determine variances from the set points and identification of one or more maintenance alerts and/or trouble events associated with variances, matching them to at least one of the events, displaying instructions to a user for resolving the event in a descending order determined by the processor of the most likely causes along with an associated solution for each cause, and providing a pre-failure solution from the stored set of instructions based on analysis of the stored data and timed sensor values.

  • Patent number: 7019988
    Abstract: An apparatus for increasing efficiency and reducing heat dissipation in power converters is disclosed. Zero-voltage-switching (ZVS) can reduce switching loss of power converters but it often results in a very complicated design and only works well under constant output current. In order to allow the ZVS to work over a wide loading range, the transformer secondary current is blocked when the primary starts to resonate. Hence, the resonant voltage waveform across the switch will not change even when the loading current is changing. Such a resonant voltage waveform is obtained with the aid of the transformer primary inductance and capacitor(s). Also provided is a novel driving circuit which controls the switching. Alternatives and variations of this apparatus can be made to satisfy different applications such as power conversion and power inversion. The subject power converter significantly lowers the heat loss and achieves higher efficiency for very wide loading ranges.
