Title: High electron mobility transistor and manufacture thereof
Inventor: KUWATA NOBUCHIKA
IPC: H01L29/812
Filed: 1989-04-26
Abstract: PURPOSE:To obtain a high electron mobility transistor(HEMT) which is economical and is highly reliable by removing selectively a part of a contact layer and further, removing only a part of an etching-stop layer by a wet etching process. CONSTITUTION:An electron channel layer 2 is joined with an electron supply layer 3 through heterojunction and a two-dimensional electron channel 9 is formed in the vicinity of the junction interface of the layer 2 and then, electrons are fed from donor impurities of the layer 3. As the electrons in the channel 9 are not scattered by the impurities, electron mobility becomes high. Further, since drain and source currents which flow between ohmic electrodes 6 are turned on through contact layers 5 and 3 as well as the channel 9, the drain and source currents flow without passing through an etching-stop layer 4 and then, the deterioration of characteristics caused by heterojunction among layers 3 and 5 as well as the layer 4, i.e., an increase for parasitic resistance is suppressed. In this way, the thicknesses of electron supply layers below a gate electrodes of each HEMT formed on the same wafer face becomes equal and an inexpensive and highly reliable HEMT is obtd.

Title: Recorder
Inventor: SAKAKI SHIGEHIRO
IPC: B41J3/00
Filed: 1987-05-01
Abstract: PURPOSE:To enable recording of information at a proper position even upon positional shifting of transfer paper, by comparing a signal obtained through integration of an output signal from a first detecting means with an output signal from a second detection means through a control means and producing a delay signal corresponding to the positional shift thereby setting the record starting position of a recording means variably. CONSTITUTION:A position detector 1 as a detecting means comprises a LED array 2 where a plurality of light emission arrays are arranged in main scanning direction and a photoreceptor array 3 containing a plurality of photoreceptors. Positional shift of a transfer paper 32 is detected by arranging the transfer paper 32 such that the end portion thereof is arranged between the LED array 2 and the photoreceptor array 3. When the transfer paper 32 is shifted in the direction of an arrow Z, voltage of an analog signal increases and the record starting position of a laser beam 27 moves by the shifting distance of the transfer paper 32. Consequently, shifted printing in main scanning direction due to positional shift of the transfer paper 32 can be prevented.

Title: Method for recognizing line kind in automatic drawing input device
Inventor: OGIYAMA NAGISA
IPC: G06T7/00
Filed: 1994-05-23
Abstract: PURPOSE:To improve the recognition of a line kind and that of a character by classifying vectors into plural specific kinds based upon a histogram prepared by the length of long and short vectors of various chain lines and the numbers of vectors and judging a line kind by the ratio of total numbers of respective vectors. CONSTITUTION:In the case of judging the recognition of a line kind by using a condition that the length values of long and short vectors in each chain line are fixed, a short vector S whose vector length is stable is noticed, and since the number of elements of a short vector S constituting each of an alternate long and short dash line, an alternate long and two short dashes line and an alternate long and three short dashes line appearing on a drawing occupies about a half or more, a histogram consisting of the length of segments and the number of segments is prepared. The periphery of the highest peak in the histogram is set up as the range of short vector length, the histogram is sorted into a short vector S and a long vector L longer than the vector S and a line kind is judged from the ratio of total numbers of respective vectors S, L. For instance, when the number of short vectors is '4' and the number of long vectors L is '5', the line kind is judged as an alternate long and short dash line. Thereby, even in the case of a chain line in which the length of a long vector is unstable, its line kind can be correctly recognized.

Title: Semiconductor wafer and semiconductor manufacturing device
Inventor: INBE TAKAYUKI
IPC: H01L21/02
Filed: 1998-04-17
Abstract: PROBLEM TO BE SOLVED: To prevent identification characters from being affected by the manufacturing process of a semiconductor device formed on a semiconductor wafer, by having characters for identifying the semiconductor wafer on the side of the semiconductor wafer. SOLUTION: A DRAM is formed in a matrix on the surface of a semiconductor wafer and characters 10A for identifying the semiconductor wafer are printed on the side of the semiconductor wafer by using laser light. To be more specific, a bar code is used for the characters 10A. Since the characters 10A are not planarized by a chemical mechanical polishing method used in a manufacturing process of the DRAM, there is no fear that they can not be read after a polysilicon film, a polycide film, or a metal film is formed. Therefore, it is not necessary to print the same identification characters several, times. Also, since devices can be made in all the surfaces of the semiconductor wafer, it is possible to increase the number of device made of one semiconductor wafer.

At a desired part, a transparent hole 4 of about 0.05-0.2μm is provided so as to form a transfer sheet 2. The heat-shrinkage factor of the film 1a in the longitudinal direction of a cylindrical body is about 0-30% and the shrinkage factor in the peripheral direction is about 20-45%. Shrinkage starts from about 100 deg.C with a heat resistance of 120 deg.C or higher. For the material, a polyester is used. For letting the design printed by the ink 3 at the time of heat-shrinkage become the desired design C1, the design 1 is formed in consideration of the heat-shrinkage factor of the film 1a at the time of non-shrinkage and printed on the film.
