  • Patent number: 10923564
    Abstract: A super-junction structure is formed by alternately arrayed pluralities of N-pillars and of P-pillars. The P-pillars are formed by P-type materials filled in super-junction trenches. The super-junction trenches are formed in an N-type epitaxial layer, each formed by a bottom trench and a top trench stacked together. A side angle of the bottom trenches is greater than 90°, and the width of the bottom surface of each bottom trench is greater than that of the top surface of the trench. The side angle of the top trenches is smaller than 90°, and the width of the bottom surface of each top trench is smaller than the top surface of the trench. The super-junction trenches are of a waisted structure. The bottom trenches increase the bottom width of the super-junction trenches and improve the depletion of the bottoms of the N-pillars, increasing the breakdown voltage of the super-junction structure.

  • Patent number: 10595415
    Abstract: An electronic device manufacturing system may include a mainframe to which one or more process chambers of different size may be coupled. A different number of process chambers may be coupled to each facet (i.e., side wall) of the mainframe. The process chambers coupled to one facet may be of a different size than process chambers coupled to other facets. For example, one process chamber of a first size may be coupled to a first facet, two process chambers each of a second size different than the first size may be coupled to a second facet, and three process chambers each of a third size different than the first and second sizes may be coupled to a third facet. Other configurations are possible. The mainframe may have a square or rectangular shape. Methods of assembling an electronic device manufacturing system are also provided, as are other aspects.

  • Patent number: 10361064
    Abstract: An electrostatic particle beam combiner for creating a single source combining the properties of two particle beams which form a high brightness source of a selected mixture of ions of varying element types and energies. An electrostatic spherical lens is arranged to bend a low energy second particle beam along a circular path and thereafter to impinge on a surface of a sample, e.g., within a transmission electron microscope. A beam of high energy is injected into the electrostatic spherical lens through an aperture in the outer shell and steered by two spaced apart electrostatic deflectors so that the angle of entry and the point of entry can be independently adjusted so that the high energy beam leaves the spherical lens along a path which is coaxial and coincident with the second particle beam of low energy.
