Abstract: PURPOSE: A method is provided to form an insulated semiconductor device in a silicon body. CONSTITUTION: A trench(20) is formed at a selected region of a silicon body(10). A barrier material is deposited on a sidewall of the trench(20). A part of the barrier material is removed from a first sidewall(32) of the trench(20) so as to be exposed the first sidewall thereof, but the other of the barrier material remains on a second sidewall(34) of the trench so as to form a barrier layer. A dielectric material is deposited in the trench(20) such that a part of the dielectric material is deposed on the exposed first sidewall(32) and the other thereof is deposited on the barrier layer. The dielectric material is annealed in an oxidation atmosphere such that the deposited dielectric material becomes dense. The barrier layer prevents an oxidization of the second sidewall(34) of the trench(20). Plural devices formed in the silicon body are insulated by the dielectric material in he trench(20).

Abstract: PURPOSE: The method for compensating leakage current in a battery is provided to properly compensate the system leakage current and the battery leakage current according to the connection environment between the battery and the system. CONSTITUTION: The interrupt is generated when the state conversion of current counter, the insert/separate of the battery, and the system leakage current are generated. The system senses if the state conversion of current counter is generated(100). When the first, second timer interrupt are needed(160), the system determines the final battery RM(Remaining Capacity) which is gained to abstract the SD(Self-Discharge) from the battery RM(170,180). When the current counter converts to the off-state, the system checks if the battery is separated from the system(120). If yes at the step 120, the system determines only the SD of the battery as the leakage current capacity(110). If no at the step 120, the system checks if the system leakage current is detected(130). If yes at the step 140, the system exits the interrupt according to the detection of the leakage current capacity. The system compensates the fixed SL at the step 190, 200. So, the final RM is the value that abstracts the SD and the SL.

Abstract: PURPOSE: A disk record medium is provided to prevent a beat from be added to extracted wobbling information. CONSTITUTION: In a disk record medium, on a disk is previously formed a groove servings a track. A physical address is written at the track by wobbling the groove. A pre-groove(GV) is formed in a spiral shape, and right and left walls are wobbled according to address information.

In a case where the groove is used as a data track, a track pitch(TP) is defined as a distance from a center of a first groove to a center of a second groove adjacent to the first groove. The width of the groove is more than that of the land. The groove is wobbled by a signal whose modulation is completed on the basis of an address, and an absolute address is extracted by performing a PM demodulation to reproduced information. The disk is rotated by a constant angle velicity(CAV) system. The number of wobbling periods of the groove provides a constant linear density(CLD), not a constant angle velocity. The number of carrier periods of a wobbling waveform is fixed at a track-line direction.
