Title: Method of manufacturing semiconductor device
Inventor: SHIOZAWA KATSUOMI
IPC: H01L21/762
Filed: 2001-04-12
Abstract: PROBLEM TO BE SOLVED: To obtain a method for manufacturing a semiconductor device which can avoid deterioration of the operational characteristics of a semiconductor element isolated by element isolation regions of a trench isolation structure even when made fine. SOLUTION: Ions 15 are implanted upwards onto a silicon nitride film 2 into a polycrystalline silicon layer 3 to obtain an ion-implanted polycrystalline silicon layer 16. Since the ions 15 are ion species of an element having enhanced oxidation action, the implantation of the ions 15 causes conversion from the polycrystalline silicon layer 3 to the ion-implanted polycrystalline silicon layer 16 having a higher oxidation rate. Thereafter, at the time of forming a thermal oxidation film 21 on an inner wall of a groove 5, an exposed part of the silicon layer 16 is also oxidized so that a polycrystalline silicon oxidation region 21a is formed relatively wide.

Title: Rfid recognition system
Inventor: ODA YASUNORI
IPC: H04B1/59
Filed: 2001-04-20
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive system capable of reducing a read failure of a RFID by a reader/writer. SOLUTION: A first antenna 10 and a second antenna 11 are arranged while the loop faces of the first and second antennas 10 and 11 do not face each other parallelly but are arranged almost at a right angle to each other. The direction of the line of magnetic force is made different at each point because the line of magnetic force from the first antenna 10 is bent by the magnetic field of the second antenna 11. Even though the RFID passes through between both antennas 10 and 11 with any attitude, the line of magnetic force by the antennas 10 and 11 acrosses the internal antenna of the RFID at a certain position, and power is thereby fed to the RFID to make the antenna 10 communicate with the antenna 11.
