Title: Formation of low-permittivity porous silica film from vapor phase
Inventor: UCHIDA TADATAKA
IPC: H01L21/316
Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To enable control of relative permittivity through deposition of a silicon insulating film of a specific material on a substrate and heat-treating the silicon insulating film to remove alkyl groups the desorption temperature which is lower than that of methyl groups from the insulating film. SOLUTION: A silicon material, containing cyanate groups without hydrogen, is reacted with a silicon material containing tertiary amine and phenyl groups in a reaction chamber 1 to deposit a silicon insulating film containing organic components such as alkyl groups on a substrate 5. A material gas is injected from a feed pipe 3 marked 'B' into the reaction chamber 1 directly or using a carrier gas. Tertiary amine supplied from a feed pipe 2 marked 'A' and a silicon material supplied from the feed pipe B3 react with each other in the reaction chamber 1, and a reaction product 7 is formed at low temperature. Thus a low-permittivity porous silica film suitable for use in reducing parasitic capacitance between conductors can be formed on a substrate at a low temperature.

Title: Method for etching polymer film
Inventor: SUZUKI YOSHITO
IPC: C08J7/00
Filed: 1989-03-27
Abstract: PURPOSE:To etch a polymer film without damaging the electrically conductive layer of a substrate by applying a magnetic field to the interior of a vacuum chamber to increase the concn. of high energy particles having a short service life and by colliding plasma contg. the particles against the polymer film. CONSTITUTION:A gas for plasma etching is introduced into a vacuum chamber 1 and electric power is supplied to a discharge electrode 2 to cause glow discharge between the electrode 2 and an earthed electrode 3. A magnetic field of at least 50G is applied to the interior of the chamber 1 with electromagnets 6. By the presence of the magnetic field, high energy particles having a long service life cause spin transformation and are rapidly transformed into high energy particles having a short service life. Plasma contg. the high energy particles at high concn. is collided against a polymer film 4 to etch the film 4. Even in the case of an increased etching rate, the electrically conductive layer of a TAB substrate is not damaged.

Title: Operation method of heat utilization system using hydrogen storage alloy
Inventor: SATO TAKERO
IPC: F25B17/12
Filed: 1991-04-09
Abstract: PURPOSE:To enhance the efficiency by achieving coincidence of head generating/ absorbing speed between the sides of generating and discharging a hydrogen occlusion heat of a heat utilizing device using a hydrogen storage alloy. CONSTITUTION:In a cooling cycle, MH-heat medium temperature difference is large on the side of generating a stored heat and small on the side of discharging or absorbing heat. To improve this, a strong vibration is applied on the side of generating a stored heat and the vibration applied is weak on the side of discharging and absorbing heat. As a result, a heat transfer coefficient between the MH and a heat exchanger tube is improved and the rate of the coefficient changes depending on the degree of vibration. The vibration is made stronger at a part with a larger temperature difference and weaker at the part with a smaller temperature difference to make a heating value equal between the sides of generating and discharging the stored heat so that the resulting generation of hydrogen can be made equal therebetween. Thus, the storing time and the discharge time of the heat utilizing apparatus can be equal eventually thereby achieving an operation with higher efficiency.
