Title: Manufacture of semiconductor wafer and analysis thereof by sims
Inventor: SAITO HISASHI
IPC: G01N23/22
Filed: 1993-08-10
Abstract: PURPOSE:To accurately measure impurity on the surface of sample wafer by SIMS by solving problems accompanied in the manufacturing steps of a sample for analysis. CONSTITUTION:A cap wafer 11 having an SOI structure is placed in close contact on the surface 2 of a semiconductor substrate (sample wafer) 1 to form a coupled wafer 21 through the heat treatment for two hours at 350 deg.C under the N2 atmosphere. Thereafter, in regard to the cap wafer, the basic Si layer 12 is etched with a mixed solution of fluoric acid, nitric acid and pure water and the SiO layer 13 is then etched by fluoric acid to manufacture a semiconductor wafer 31 having the structure that a thin film Si layer 14 is provided on the surface 2 of the semiconductor substrate 1. This semiconductor wafer 31 is then subjected to analysis by SIMS. Since the semiconductor substrate is quickly capped, contamination of the semiconductor substrate surface can be prevented. Moreover, since coupling can be done with a low temperature heat treatment, impurity at the semiconductor substrate surface is never diffused into the inside and vaporization of substances which may be vaporized at a comparatively lower temperature during manufacture of sample can also be prevented.

Title: Adhesive tape applying device
Inventor: IDE YOSHIKAZU
IPC: B65H37/04
Filed: 1987-09-02
Abstract: PURPOSE:To automatically carry out a cutting step, an applying step and an adjusting step by providing an elevation guide plate for guiding a roll on a bell crank so as to elevate and guide a rod. CONSTITUTION:A roll 34 on a bell crank lever 31 makes contact with the lower part of a tapered part 42a on a guide plate 42 so as to ascend, and accordingly, a rod 23 is elevated. In association with this operation, a tape adhesion mechanism attaching plate 12 which is inclined so as to elevate the nip roll 17 side is lowered about a pivotal shaft 13 so as to continue its advance, and accordingly, the nip roll 17 presses an adhesive tape 51b against a retaining roll 18 while the tape 51b is applied onto a sheet surface 10. Accordingly, an outer housing 41 attached with the guide plate 42, slides right and left for adjustment along a guide lever 44 in accordance with the width of the sheet 10 so as to be positioned and adjusted. When a travel frame 11 is advanced further, the rod 23 is moved forward by the resilient force of a spring 33 without being lowered even though the roll 34 on the bell crank lever 31 moves away from the top part of the guide plate 42. Accordingly, the bonding and pressing of the adhesive tape onto the sheet surface 10 may be continued.

Title: On-vehicle communication equipment
Inventor: FUTAMI TORU
IPC: H04L7/00
Filed: 1986-09-18
Abstract: PURPOSE:To simplify the circuit constitution and to preclude the possibility of mis-transmission of data by adopting a data active logic of a synchronizing device and a transmitter as a positive logic and using only 'L' level period for the master synchronizing period. CONSTITUTION:A synchronizing device 4000 generating alternately the master synchronizing period decided by connecting or not connecting a communication line 5000 and a power line 1000 for a prescribed time and plural channel periods, a transmitter 6000 discriminating the designated channel period, detecting the connection of the synchronizing device and the communication line in the period and sending a pulse data, and a receiver 7000 discriminating the designated channel period, detecting the connection of the communication line and the power line 6100 of the transmitter in the period and giving a reception output in response to the data positive pulse width are provided. Through the constitution above, since the synchronization is caught by the leading/trailing of the positive pulse on the communication line, the circuit constitution is simplified. Since the data is discriminated by a positive pulse width, even if momentary interruption or short-circuit takes place in the communication line, the circuit acts on the fail-safe side at all times thereby offering the safety.
