Filed: 1999-04-26
Abstract: PROBLEM TO BE SOLVED: To align a target with a reference position with high accuracy, even after a wafer is subjected to CMP(chemical-mechanical polishing) process. SOLUTION: At exposure of a resist film, formed on a wafer which carries Cu wiring formed by damascene method and is subjected to a CMP process to the original image of a reticle by projecting the image in reduction upon the resist film, the wafer is aligned by using a target 8 constituted by alternately arranging a plurality of lines 8a, each of which is composed of a dot pattern 8c and a plurality of spaces 8b. Since each line 8a of the target 8 is formed by using the dot pattern 8c, the occurrence of defective shapes can be prevented, even after the wafer is subjected to the CMP process. Therefore, the alignment accuracy of the target with a reference position can be improved, because the target 8 can be recognized with accuracy at performing of the alignment.

Title: Ion implantation method into trench
Inventor: KASE MASATAKA
IPC: H01L21/822
Filed: 1987-05-13
Abstract: PURPOSE:To form a thin diffusion layer into a trench, and to improve reliability by irradiating the side wall of the trench with light ions to shape a light-ion diffusion layer and irradiating the bottom with heavy ions to form a heavy-ion diffusion layer. CONSTITUTION:Light ion beams 2 having the small mass number such as phosphorus are injected to the side wall of a trench 1a shaped to an silicon substrate 1. Repulsion is inhibited by acceleration energy higher than Thomas-Fermi- energy, and said light ion beams 2 are injected efficiently. The depth of a diffusion layer is adjusted so as to be brought to the same extent as the depth of a diffusion layer by said phosphorus, and ions are implanted. When heavy ion beams 4 having the large mass number such as arsenic are used at that time, a heavy ion diffusion layer 5 can be shaped without lowering acceleration energy. Accordingly, light ions are implanted to the side wall of the trench 1a, heavy ions are implanted to the bottom, and ions are implanted in response to each section, thus forming the uniform thin diffusion layer in the trench 1a.

Abstract: PURPOSE:To simplify a circuit structure, save a current consumption and extend a backup time by a method wherein a reading operation is performed to a memory space which is the object of refresh during a mask-impossible interrupt 0-processing program by a CPU. CONSTITUTION:Normally, a CPU l does not have a competition against a refresh request signal 14 at the time of an aaccesss operation to a dynamic memory 5 and performs the memory access operation with a predetermined timing given by a timing circuit 3. At the time of a memory refresh operation, a refresh timer 2 outputs a signal 14 and the CPU 1 inputs the signal 14 to an NMI input. As the NMI is mask-impossible, the CPU l interrupts the process presently practiced and starts the practice of an NMI processing program and executes a reading operation to all the memory spaces of a memory 5 which is the object of refresh. With this constitution, the memory refresh can be performed, so that the circuit structure can be simplified, the current consumption can be saved and the backup time can be extended.

Abstract: PURPOSE:To print and record a character or image having recording density higher than the arrangement density of nozzles, by providing a displacement means for minutely displacing a multi-nozzle head in the nozzle arranging direction of the head and a control circuit for displacing the displacement means in synchronous relation to a printing signal. CONSTITUTION:When pulse voltage is applied between lead wires 51, 52 and 53, 54 to be applied to displacement units 4, these displacement units 4 displace and a head 1 displaces in the arranging direction (X-direction) of nozzles 11-110. However, since each of the displacement units 4 is formed by laminating a vibration plate 4a and an electrostriction vibration plate 4b and fixed to a head support table 3 in a cantilevered fashion, the displacement units 4 displace in the arranging direction (X-direction) of the nozzles 11-110 as a whole. Further the displacement units 4 can be also displaced reversely according to the polarity of voltage to be applied and the polarizing direction of a vibrator. Furthermore, displacement quantity can be controlled by the magnitude of voltage to be applied and, when the voltage to be applied is brought to 0, the displacement units 4 return to the original state.
