Abstract: PURPOSE:To obtain a highly efficient bilaterally rotatable drive motor having simple structure and high design freedom and can be miniaturized by generating the ridge of standing wave through the use of bending vibration and disposing a protrusion at a position shifted from the ridge of the standing wave thereby generating an elliptical motion directly on the protrusion. CONSTITUTION:A stator section 40 comprises piezoelectric ring elements 42, 44, and first and second planar blocks 50, 52 arranged to hold electrode plates 46, 48 laminated on the surfaces of the piezoelectric elements 42, 44. A radial protrusion 62 is formed on the end face of the block 50 and a single phase AC voltage having resonance frequency of bending vibration is applied on every other split electrode plate arranged on the ring under a state where the second electrode plate 48 is grounded. Consequently, elliptical motion is generated on the protrusion 62 of the metal block 50 for rotary driving the rotor section 30. When the region to be applied with single phase AC voltage is switched, elliptical motion is generated in the opposite direction on the protrusion 62 and the rotor section 30 rotates reversely.

IPC: H01L21/28
Filed: 1992-05-11
Abstract: PURPOSE:To improve an electromigration resistance by forming an ordinary Al-Si alloy on a substrate at a high temperature by means of a sputtering method, by introducing impurity species by means of ion implantation after the substrate has been subjected to photolithographic etching, and by causing the impurities to be deposited by means of a heat treatment. CONSTITUTION:An Al-Si alloy film 203 having a large crystal grain is formed by carrying out sputtering at a high temperature. A line is formed by photolithographic etching, and impurities such as Hf and B are then introduced by ion implantation. The film is then subjected to a heat treatment. The heat treatment is performed at a temperature of 400 deg.C for fifteen minutes in an atmosphere of H2. This heat treatment causes the recovery of damages caused by the ion implantation, and also causes the implanted impurities to be diffused and deposited. Thereby, it is possible to finish a strengthened line with an improved electromigration resistance that is less susceptible to the occurrence of hillocks and voids.
