Title: Electron beam exposure apparatus and adjusting method for same
Inventor: DAIKYO YOSHIHISA
IPC: H01L21/027
Filed: 1990-11-27
Abstract: PURPOSE:To improve resolution of the peripheral area of deflecting region by changing a relative value of deflection by a deflector in each stage for setting the strength of lens having small deflection aberration. CONSTITUTION:Currents of deflectors 19a to 19d are changed independently, strength of lens is set to a certain value and the same current is applied in the different manner with time to the deflectors 19a to 19d of the four stages. Thereby, the electron beam is deflected like 19a to 19d as indicated by the arrow mark. This deflection is indicated by a locus of the electron beam in which aberration is minimized at the projecting point. Each deflection and relative value thereof are computed by simulation as 1, 0.8, 0.6, 0.2 in the deflectors of the four stages. The strength of lens which provides such relative value of the deflection lies in the point P, a projection lens is set to the optimum lens strength P and a compression lens strength is determined to allow that an aperture image to be focused on the sample surface. Thereby resolution of the peripheral area of the deflection region can be improved.

Title: Composite semiconductor device
Inventor: FUKUDA EIGO
IPC: H01L25/18
Filed: 1999-11-15
Abstract: PROBLEM TO BE SOLVED: To obtain a highly reliable composite semiconductor device for high power by eliminating the crossing portion of bonding wires. SOLUTION: The flat plate type DC side conductor terminals 120, 130, 3-phase AC side conductor terminals 9, 10, 11 and signal conductor terminals 7, 8 are inserted and molded to form a double-layer laminated structure within sidewalls 6A, 6B, 6C, 6D of an insulated resin case 2. In this case, wiring can be made for the flat plate type DC side conductor terminals, using many bonding wires on the average. Since the wires are concentrated not only at an area at the end portion of the conductor terminals, voltage drop is rather small. Moreover, since it is no longer required to provide an extension conductor pattern, the structure may be simplified. In addition, since the wires will not cross each other, reliability is improved, and a large power composite semiconductor device can be obtained.
