Title: Semiconductor substrate and method of manufacturing the same
Inventor: OKAGAWA HIROAKI
IPC: H01L21/20
Filed: 2001-03-12
Abstract: PROBLEM TO BE SOLVED: To eliminate various problems which result from the use of a mask layer, and to simplify a manufacturing process. SOLUTION: As shown in Fig. (a), a substrate 1 having an uneven growth face is prepared. When conducting a vapor phase growth using this substrate, the uneven shape of the growth face suppresses the lateral growth, while accelerating the growth in the C axis direction, making the uneven growth face advantageous as a foundation face for forming a facet surface. Consequently, as shown in Fig. (b), crystals are grown on the projecting parts formed with the facet surfaces, while made to grow in the recessed parts also. In the crystal growth is continued, films grown from the projecting parts and recessed parts are jointed together and flattened, while covering the uneven face as shown in Fig. (c). In this case, low-displacement regions are formed in the upper parts of the projecting parts formed with the facet surfaces, and a high-quality film can be manufactured.

IPC: C23C14/22
Filed: 2001-04-02
Abstract: PROBLEM TO BE SOLVED: To provide a film forming method which can form a functional thin film on the surface of a low melting substrate like plastic plates, without causing deformation and failure. SOLUTION: The film forming method comprises forming a precursive film on the surface of the substrate K composed of plastics, by depositing copper ions which are generated by a treatment sauce 4 (a FCVA ion source), and implanting oxygen ions in the plasma which has been generated by a treatment source 2 (a Kaufman type ion source) into the precursive film, in the state that pulsed voltage including positive pulse voltage and negative pulse voltage is applied on the substrate K, to form the functional thin film consisting of cuprous oxide. Thereby, the functional thin film is formed on the surface of the substrate K, without causing problems such as deformation or damage during film formation, because the film forming temperature (less than about 100 deg.C) is lower than that in a conventional dynamic mixing method (about 300 deg.C to 400 deg.C).

Title: Terminal metal fitting
Inventor: SAKA YUKINORI
IPC: H01R13/42
Filed: 2001-04-04
Abstract: PROBLEM TO BE SOLVED: To make a passage area at the time of connector insertion into connector housing small. SOLUTION: A female terminal metal fitting 1 consists of a fitting body 9 and a shell 10 which covers the fitting body 9. A lance 19 for stopping omission of the female terminal metal fitting 1 is formed in the shell 10 by carrying out cut-and-rise. Behind the lance 19, a lance protection wall 21 is formed with standing-up formation. In the former one such what protects the lance 19 by a stabilizer, since the stabilizer has projected in a position distant from the lance 19 in a width direction, in order to avoid this, an insertion opening of connector housing 2 needs a big cross-section area. However, here, since the lance protection wall 21 is made almost the same as the width size at the back of the lance 19, the area of the entrance portion of the seal pipe part 7 of the connector housing 2 can be made small.
