Title: Manufacture of thin film transistor matrix
Inventor: ENDO TETSURO
IPC: G02F1/1368
Filed: 1987-10-22
Abstract: PURPOSE:To manufacture a thin film transistor matrix whose parasitic capacity is small without complicating the manufacturing process by making an unnecessary part soluble by an auxiliary exposure continued from a back exposure. CONSTITUTION:An image reversal photoresistor film is used, an intersection part is exposed and a heating treatment is performed, and a part to be exposed is made insoluble against a developer. Subsequently, by a back exposing method, a picture element electrode E part and a drain bus line DB part become soluble, and a pattern edge of a gate electrode G is delimited as self-matching. In the end, by performing an exposure to other part than a pattern containing the gate electrode G and a gate bus line GB and an unnecessary part becomes soluble, and by executing a development processing, a resist film is formed. Also, this resist film is used as a mask and a transparent conductive film is removed by etching. In such a way, an overlap of the gate electrode G and the picture element electrode E, namely, a source electrode S can be reduced, and the parasitic capacity CGS can be decreased.

Title: PREPARATION OF SAMPLE FOR TRANSMISSION ELECTRON MICROSCOPE OF GaAs, GaN-BASED COMPOUND SEMICONDUCTOR AND LAMINATED STRUCTURE ANALYSIS BY USING IT
Inventor: MATSUE TERUYUKI
IPC: H01J37/20
Filed: 1998-09-22
Abstract: PROBLEM TO BE SOLVED: To remove a produced amorphous layer, and to prepare a sample suitable for laminated structure analysis of film thickness analysis or the like, by executing a wet chemical etching by using an optional solution after a focused ion beam work in preparing the sample. SOLUTION: Sputtering is executed by irradiating a focused ion beam on both sides of an observation region 6 of a sample, to thereby execute film-thinning of the observation region 6 until observation by a transmission electron microscope becomes possible. In this case, crystals inside the observation region 6 are changed into the amorphous state up to the depth of several ten- to several hundred-Å from the surface of a work face, by receiving the influence of extension in the vertical direction of the focused ion beam irradiated to the sample. Then, after the focused ion beam work, wet chemical etching is executed to remove the amorphous layer. The wet chemical etching is executed by a chemical reaction between a solution and a sample, after immersing the sample into the solution. As the solution, for example, in case of GaAs-based compound semiconductor, acid solution, such as phosphoric acid, hydrochloric acid or the like, with a concentration of 0.01-0.1 wt.% is used, especially phosphoric acid being preferable.

Abstract: PROBLEM TO BE SOLVED: To easily divide a substrate with a small cutting-margin by applying an external force to the substrate, projecting light to the part, wherre stress caused by the external force is concentrated, of the substrate, and generating a crack with the heat of the projected light. SOLUTION: A wafer 1 is stuck on a tape 2, and by stretching tape 2 radially outward, a tension T is applied to the tape 2. In this state, the thrust piece 6 is moved up to warp the wafer 1 convexly. The wafer 1 is raised into a roof shape by the generally linear contact of a linear tip part of the thrust piece 6 with the tape 2. The laser beam of a light source 8 is projected through an optical lense 9 onto the part where stress caused by the thrust piece 6 is concentrated, i.e., the edge of the curved part. During the laser projection, a specified tension is applied by holding members 3 and 4 on both sides of the edge of the wafer 1, and hence a crack is generated at the edge by the thermal stress due to the heating of the laser light. Further with the reception of the external force load from the thrust-piece 6, division is performed along the edge.
