Abstract: PURPOSE:To form an LDD of an opposite conductivity type by a method wherein an insulating sidewall layer is formed so as to come into contact with a gate electrode and ions on impurities of the opposite conductivity type are implanted at low concentration through the sidewall layer form a direction which is oblique to the surface of a semiconductor substrate. CONSTITUTION:A gate electrode 3 is formed in an element formation region in a semiconductor substrate 1; then, an SiO2 layer is deposited on the whole surface of the semiconductor substrate 1; the surface of the semiconductor substrate 1 is etched from the perpendicular direction; and a sidewall layer 7 is formed so as to come into contact with the gate electrode 3. Then, a mask 8 which selectively exposes, e.g. an n-channel MOS transistor formation region is formed; and after that, ions of impurities are implanted from a direction at an impingement angle theta of, e.g. 45 deg. to the surface of the semiconductor substrate 1. The depth of the implanted impurities is changed according to the distance in the sidewall layer 7 through which the impurities are passed. However, the depth is reduced gradually toward a channel region, and n-type LLD's 10 are formed. In addition, ions of high-concentration impurities are implanted by giving an inclination at an impingement angle theta of about 7 deg. from a direction substantially perpendicular to the surface of the semiconductor substrate 1. Thereby, it is possible to form an n-type source and an n-type drain whose junction depth is uniform and whose concentration is high.

Abstract: PURPOSE:To prevent the difference of surface temperatures due to the accumulative effect of the heat of heat-generating section, and to obviate the unevenness of density by relatively displacing mutually adjacent heat-generating resistor dots in the direction of feeding of paper or the head. CONSTITUTION:In the thermal head consisting of head-generating resistor dot groups 4, 5 formed onto an insulator substrate 3 in rows, electrode groups 2 holding these dot groups and protective layers shaped onto these dot groups and electrode groups, the mutually adjacent heat-generating resistor dots 4, 5 are formed while being alternately displaced only by length 12 as the reciprocal of the density of by-scan in the direction 13 of by-scan. Accordingly, a thermal effect among the dots adjoining in the direction of main scan can be reduced because each heat-generating resistor dot is separated and the color-forming dots having density and size in the same extent can be shaped in the thermal head in which the positions of the heat-generating resistor dots are alternately displaced.
