Patent number: 6377461Abstract: A method of power electronic packaging includes a practicable and reliable method of fabricating power circuit modules and associated connections that are compatible with the standard top layer metalization of commercially available power devices. A planar single- or multi-layer membrane structure is attached to a carrier frame, and a via pattern is formed in the membrane. Power devices are aligned and attached to the planar membrane structure; a top layer interconnect structure is formed by metalizing the vias and the film; and a circuit is formed by patterning a deposited metal layer. The carrier frame is removed, and upper and lower thermal base plate sub-assemblies are attached to the power device-on-membrane structure. The planar device-on-membrane structure accommodates different types of power devices having variations in thickness. The thermal base plate sub-assemblies may include integral, high-performance heat exchangers for providing a low thermal resistance path to the ambient.Type: GrantFiled: November 10, 2000Date of Patent: April 23, 2002Assignee: General Electric CompanyInventors: Burhan Ozmat, Mustansir Hussainy Kheraluwala, Eladio Clemente Delgado, Charles Steven Korman, Paul Alan McConnelee

Patent number: 5959357Abstract: A FET package including one or more FETs includes an arrangement of three metallization layers for the gate, drain, and source terminals thereof. The layers include a gate runner metallizaton layer that allows the FETs to be arranged in a parallel manner so as to reduce the overall total on-state resistance to an optimum value, while allowing the gate switching capacitance to be increased to an optimized value. The gate runner metallization layer is arranged to minimize the overlapping capacitance between the gate and source terminals and between the gate and drain terminals. Additional semiconductor devices may be incorporated into the FET package using additional terminals interconnected through the metallization layers, thus providing additional functions.Type: GrantFiled: February 17, 1998Date of Patent: September 28, 1999Assignee: General Electric CompanyInventor: Charles Steven Korman

Patent number: 5745981Abstract: A magnetic or electromagnetic circuit component includes an embedded magnetic material (e.g., ferromagnetic) in an HDI structure with alternating dielectric and metal or winding layers. In one embodiment, the ferromagnetic material is situated in a substrate well, or cavity, with or without an adhesive. Alternatively, the ferromagnetic material is co-fired with the ceramic substrate and then machined to achieve a required core shape. An electroplating process is employed to construct the metal layers, such process including differential plating for varying the thickness of metal layers and/or other portions of the circuit. Laser ablation or any other suitable technique is employed to make through-holes for insertion of the posts of a ferromagnetic core plate used to complete a magnetic circuit, if required. Advantageously, a magnetic or electromagnetic component may have a height of less than about 0.1 inch.Type: GrantFiled: January 18, 1996Date of Patent: May 5, 1998Assignee: General Electric CompanyInventors: Waseem Ahmed Roshen, Charles Steven Korman, Wolfgang Daum
