Abstract: PURPOSE: To augment the probability of ion introduction into a semiconductor substrate, even if contaminated, by a method wherein an ion implanting mask patterns are formed to cross over-introduce ions several times for cleaning away any foreign particles from a semiconductor substrate during the ion implanting step. CONSTITUTION: Firstly, a cleaning preventive oxide film 111 is formed on a semiconductor 100. Next, the first mask patterns 101 are formed for ion- implanting on the specific positions L1-L6 of the semiconductor substrate 100 to perform the first time ion-implanting step. Through these producers, the ions are implanted in respective positions of L1-L3, L5, L6 but the ions are not implanted to the position L4 covered with a foreign particle 102. Next, the first mask pattern 101 is removed and then the second mask pattern 104 is formed on the same position as that of the first mask pattern 101 to perform the second time ion implanting step. Through these procedures, the other foreign particles 105 stay in the position L6 to avoid the ion-implantation but the ions are implanted by the first time ionimplanting step.

Title: Magnetic recording body
Inventor: GOTOU FUMIO
IPC: G11B5/65
Filed: 1984-05-31
Abstract: PURPOSE:To sharply improve the overwrite characteristic of a magnetic recording body without spoiling the high-density characteristic extensively, by setting the value of the magnetic anisotropic energy of the storage medium of the magnetic recording body to a specific range. CONSTITUTION:In order to make high-density recording by using a ring head, the magnetic anisotropic energy of the storage medium of a magnatic recording body is set to values within a range of -10X10<5>erg/cc<=Ku<=0. The recording density characteristic is increased as the Ku of the storage medium is increased, but the increasing degree becomes less when the Ku is -10X10<5>erg/cc or more. On the other hand, the overwrite characteristic of the recording medium deteriorates as the Ku positively increases. In case of mixed mode in which perfect vertical recording is not performed, an excellent overwrite characteristic is obtained without lowering the recording density extensively when the recording is performed on the magnetic recording body with a medium, whose Ku value is set in the range of -10X10<5>erg/cc<=Ku<=0, by using a ring head.
