摘要： In a non-isolated DC/DC converter, a reference potential for a low-side pre-driver which drives a gate of a low-side MOSFET is applied from a portion except for a main circuit passing through a high-side MOSFET and the low-side MOSFET so that a parasitic inductance between a source of the low-side MOSFET and the pre-driver is increased without increasing the sum of parasitic inductances in the main circuit and negative potential driving of the gate of the low-side MOSFET can be performed and a self turn-on phenomenon can be prevented without adding any member and changing drive system.

摘要： In manufacturing a semiconductor integrated circuit device, an interconnect trench and a contact hole are formed in an interlayer insulating film formed over a first-level interconnect on a semiconductor substrate, a barrier film is formed inside of the trench and contact hole so that its film thickness increases from the center of the bottom of the hole toward the sidewalls all around the bottom of the contact hole, a copper film is formed over the barrier film, and a second-level interconnect and a connector portion (plug) are formed by polishing by CMP. In this way, the geometrically shortest pathway of an electrical current flowing from the second-level interconnect toward the first-level interconnect through a connector portion (plug) does not coincide with a thin barrier film portion which has the lowest electrical resistance, so that the current pathway can be dispersed and a concentration of electrons does not occur readily.

摘要： In forming five trenches buried with an intermediate conductive layer for connecting transfer MISFETs and driving MISFETs with vertical MISFETs formed thereover, in which the second and third trenches, and the first, fourth, and fifth trenches are formed separately by twice etching using first and second photoresist films as a mask. Since all the trenches can be formed at a good accuracy even in a case where the shortest distance between the first trench and the second or third trench, and the shortest distance between the second or third trench and the fourth trench is smaller than the resolution limit for the exposure light, the distance between each of the five trenches arranged in one identical memory cell can be reduced to be smaller than resolution limit for the exposure light.

摘要： A technique is provided which permits formation within a single chip both a field effect transistor of high reliability capable of suppressing the occurrence of a crystal defect and a field effect transistor of a high integration degree. In a mask ROM section having an element isolation region with an isolation width of smaller than 0.3 μm, a planar shape of each active region ACT is made polygonal by cutting off the corners of a quadrangle, thereby suppressing the occurrence of a crystal defect in the active region ACT and diminishing a leakage current flowing between the source and drain of a field effect transistor. In a sense amplifier data latch section which is required to have a layout of a small margin in the alignment between a gate G of a field effect transistor and the active region ACT, the field effect transistor is disposed at a narrow pitch by making the active region ACT quadrangular.

摘要： An encoding/decoding operation portion includes an encoding/decoding operation circuit and an avoiding path for detouring the encoding decoding operation circuit and can select between encoding or decoding input data in the encoding/decoding operation circuit and detouring the encoding/decoding operation circuit to output the input data without change. Only one wire has to be provided from a selector to a key storage portion and an initialization-vector storage portion. With this construction, it is possible to realize an encoding/decoding circuit which can suppress an increase in the number of wires used to transmit a content of key data to the key storage portion and the initialization-vector storage portion and does not cause complication of circuit layout.
