Filed: 1988-04-18
Abstract: PURPOSE:To provide a small shield plate type interelement isolation region by oxidizing the surface of a polycrystalline silicon layer to yield an insulating layer of a desired thickness, removing the insulating layer to make the polycrystalline silicon layer a small size, and oxidizing the same again. CONSTITUTION:A silicon dioxide layer 2 and a polycrystalline silicon layer 3 are formed on a silicon semiconductor substrate 1 in order, and the polycrystalline silicon layer 3 is patterned as a shield plate. Then, the whole surface, particularly the polycrystalline silicon layer 3 is oxidized to form an interlayer insulating layer 5, which is thereafter removed. The width of the polycrystalline silicon layer 3 after the foregoing process is approximately half the thickness of the interlayer insulating layer 5 or reduced by a fraction correspondingly to the thickness of the interlayer insulating layer 5 on both sides of the substrate. Accordingly, if a shield plate type interelement isolation structure is formed thereafter as usual, then the width of the polycrystalline silicon layer 3 can be reduced. Hereby, a small shield plate type interelement isolation region is yielded, which can not be found in a minimum line width determined by a present photolithography technique.

Abstract: PURPOSE: To provide a DC/DC converter which performs switching of an operation mode by detecting the load current with small current consumption. CONSTITUTION: A comparator 2 monitors output voltage Vout . Comparators 3 and 4 monitor coil currents IL and control the power supply cycles. When the output voltage Vout falls under the preset reference value, it starts the power supply cycle, and also, increases the count value of a counter 12.
