Title: Temperature measuring method for semiconductor fine wiring by microscopical fluorescent spectrometry
Inventor: YAMAGUCHI HIROKATSU
IPC: G01J5/10
Filed: 1995-05-29
Abstract: PURPOSE:To measure the temperature of fine wirings of several mum of semiconductor by measuring a plurality of the positions of the temperatures of an insulating film, obtaining a temperature gradient, and extrapolating it for the position of the wirings. CONSTITUTION:Symbol W is wirings; P1, a nonfluorescent insulating film; P2, a fluorescent insulating film; and S, a board. Temperatures T(0), T(x), etc., are measured at the two or more positions of the film P2. These temperatures are represented by the function f(r) of the distance (r) from the center of the wirings and a coefficient (a) by T=af(r)+T0. The f(r) is obtained by using a finite element method. The coefficient (a) is obtained by using the actually measured values of the T(0), the T(x), and the wiring temperature is estimated by extrapolating the above formula for the position of the wirings. According to this, fluorescent is measured from the plurality of the positions of the film P2 even on the wirings of the width of 1mum or less, and the temperature gradient is obtained to measure the temperature of the wirings. This is useful for predicting the life of the wirings. Further, abnormal heat generation of the infinitesimal position of the wirings can be detected, and also useful for detecting a defective position.

IPC: G11B5/027
Filed: 1989-05-24
Abstract: PURPOSE:To prevent the saturation of a signal at the time of recording and the mixture of noises at the time of reproducing and to prevent image quality from being deteriorated by connecting an analog switch to a magnetic head in series and increasing a control current for the analog switch at the time of recording more than at the time of reproducing in accordance with the operation mode of a device. CONSTITUTION:The analog switches 3 and 4 are connected to the magnetic head for an SP 1 and the magnetic head for an LP 2 in series directly or through rotary transformers 5 and 6, and current generating means 7 and 8 which input an operation mode signal showing whether recording is performed or reproducing is performed in the device and generate the larger current at the time of recording than at the time of reproducing as the control current for the analog switches 3 and 4 are also provided. Since the control current for the analog switches 3 and 4 is made large enough to apply a large quantity of recording signal current to the magnetic heads 1 and 2 at the time of recording, the image quality is prevented from being deteriorated by the limit of a recording current. By decreasing the control current for the analog switches 3 and 4 at the time of reproducing, the noise component of the control current is prevented from being mixed in a small reproducing signal current and the image quality is improved.

Filed: 1991-06-03
Abstract: PURPOSE:To avoid erroneous input and to input multilevel information by detecting coordinates with plural coordinate detection screen layers and correcting erroneous input due to parallax and invalidating coordinate input in areas other than a designated area. CONSTITUTION:In a multilayered coordinate detection screen 1 arranged on a display device, the coordinates of a designating point on the display device are corrected based on the coordinates of first and second layers taken in correspondingly to the interception of both layers. When the coordinates of both layers taken in correspondingly to the interception of 1st and 2nd layers are different, this coordinate input is invalidated, and an operator is prompted to perform both inputs. Information of layers fetched correspondingly to the interception of 1st, 2nd,...n-th layers are obtained as multilevel information. Consequently, coordinates are detected by plural coordinate detection screen layers, and erroneous input due to parallax is corrected, and the coordinate input in areas other than the designated area is invalidated to avoid the erroneous input, and multilevel information can be inputted.

Abstract: PURPOSE:To easily draw and display pictures by arranging the thin film conductors on a transparent plastic film in a grid form where these conductors are electrically insulated from each other and obtaining a coordinate position detecting part consisting of an X-Y axis orthogonal circuit. CONSTITUTION:The thin film conductors 2 and 3 are formed on the upper surface side and the rear surface side of a plastic film 1, respectively. These conductors are arranged in parallel with spaces secured among them on both sides of the film 1 so as to obtain an X-Y axis orthogonal circuit where the conductors 2 and 3 are regularly arranged in a grid form. Both conductors 2 and 3 must be adhered to the film 1 and this requirement is easily attained by a pattern printing or plating process, etc. Thus a coordinate position detecting part is obtained by arranging fixedly the conductors 2 and 3 on the film 1. For instance, the data on patterns, etc., are put under the position detecting part and then traced by a cursor or a stylus pen over said detecting part. Thus the pictures can be drawn and displayed in an extremely easy way.
