Title: Semiconductor thin film and manufacture thereof
Inventor: SETSUNE KENTARO
IPC: H01L21/205
Filed: 1999-06-11
Abstract: PROBLEM TO BE SOLVED: To form a crystalline silicon film at a low temperature by forming an atomic layer and a layer, having a peak concentration of a catalyst element around an interface between a substrate and a semiconductor thin film, and subsequently made to contain the catalyst element in and outside the semiconductor thin film. SOLUTION: On a glass substrate 1, a coating 2 made of a material such as silicon oxide is formed through sputtering method, and then a semiconductor thin film 3 such as a crystalline silicon film is formed thereon. Subsequently, around an interface 4 between the substrate 1 and the semiconductor thin film 3, an atomic layer is formed, which contains a catalyst element for accelerating the growth of a crystal. Furthermore, a layer having a peak concentration of the catalyst element is formed around the interface 4 between the substrate 1 and the semiconductor thin film 3, and the catalyst element is contained in and outside the semiconductor thin film 3. Therefore, it is possible to manufacture a semiconductor thin-film device, such as a low-temperature forming thin- film transistor having high performance.

Title: Current mirror circuit
Inventor: FURUYA YOSHINAGA
IPC: H03F1/56
Filed: 1988-07-04
Abstract: PURPOSE:To obtain the same electric current as an input current at an output terminal by compensating at least base currents of the 1st and 2nd transistors with an inverted current proportional to the base current of the transistor. CONSTITUTION:A base current ib4 which is almost the same as the base current ib3 of a transistor Q3 flows to the base of a transistor Q4 and is inputted to an inverted current generation circuit 2. The electric current which tends to flow to an input terminal IIN through the diode connecting section of a transistor Q1 is equal to an electric current which is three times as large as the base current of the transistor Q1. Moreover, since an electric current which is three time as large as the base current ib1 is forcibly made to flow to the collector of the transistor Q6 of the circuit 2, no base current flows to the input terminal IIN. Therefore, an electric current i2 which is equal to the electric current inputted to the input terminal IIN is obtained from an output terminal IOUT and the potential difference between the input terminal IIN and a supply voltage +VCC becomes the forward voltage across the base and emitter of the transistor Q1 only when a voltage drop caused by a resistance R1 is ignored.

Abstract: PURPOSE:To make calibration accurate and easy, by forming a calibrating weight in an approximately ring shape in a plane, and making the agreement of the center of gravity of the calibrating weight and the center of gravity of a material to be measured easily. CONSTITUTION:The plane of a calibrating weight 1 is of a ring shape. The center of gravity of the weight 1 agrees with the axial center of a pan attaching member 9 of an arm 7.

A supporting member 12, which supports the load of the weight 1, is formed in an approximately U-shape in a plane. The weight 1 is supported by both sides of the arm 7. Since a supporting point 2a and the contact part of the supporting member of a cam 3 become power points, the contact point of the calibrating weight, which is a working point, is lifted and lowered when the cam 3 is turned. By adjusting the lifting and lowering, the load of the weight 1 working on the arm 7 is adjusted. Thus, the balance is calibrated. At this time, an engaging cam 4 is engaged with a stopper 5. Thus, the cam 3 is turned and arranged at a specified position and fixed.
