Abstract: PURPOSE:To efficiently obtain a rutile single crystal without any lattice defects by cutting the rutile single crystal into the form of a wafer so as to cross the c-axis of the crystal axis, coating the surface with a thin film of a specific inorganic compound and heat-treating the coated wafer. CONSTITUTION:A rutile single crystal is grown by a floating zone method, etc. The resultant rutile single crystal is then cut into the form of a wafer so as to cross the c-axis of the crystal axis. The surface is then coated with a thin film of any one selected from TmO2, Al2O3, SiO2, Ga2O3 K2CO3 Na2CO3 and ZrO2 and heat-treated at about 1000 deg.C temperature. Thereby, the thin film component acts during the heat treatment and the atomic sequence of the rutile single crystal is ideally rearranged to remove lattice defects. Furthermore, the lattice defects can be prevented from occurring in the heat treatment. A method for previously heat-treating the rutile single crystal, producing cracks or subgrains, then coating them with the thin film of the inorganic component and further heat-treating the coated single crystal is used.

Title: Top tape
Inventor: SUZUKI SATOSHI
IPC: H05K9/00
Filed: 1997-11-20
Abstract: PROBLEM TO BE SOLVED: To reduce the scattering in sealing strength while maintaining electrification prevention effect and always make constant peeling strength and improve working efficiency, by forming an electrification prevention layer on a surface other than a lamination surface with a carrier tape. SOLUTION: An electrification prevention agent is uniformly applied to or sprayed onto the entire, upper surface of a base 2, thus forming an electrification prevention layer 3. On the other hand, an electrification prevention layer 5 is formed by applying or atomizing the electrification prevention agent to the lower surface of the base 2 and at least one portion of a surface other than a lamination surface with a carrier tape 6 of an adhesive layer 4. A surfactant such as an anion activator, a cation activator, an activator with both properties, and a nonionic activator is used for the material of the electrification prevention layers 3 and 5. The thickness and the surface resistance of the electrification prevention layers 3 and 5 should preferably be 0.1-0.4 μm and 10<7> -10<12> Ω/(square) respectively.  In this manner, no electrification prevention agent is formed on the lamination surface with a carrier tape 6 in a top tape 1, thus improving a sealing property and obtaining a stable peeling strength.
