Title: Device for forming thin film
Inventor: HOSHINOUCHI SUSUMU
IPC: H01L21/285
Filed: 1986-03-24
Abstract: PURPOSE:To form a thin film high in reliability in such a state that a base plate is maintained at room temp. by projecting both ultraviolet laser beams dissociating gas for film formation and pulse laser beams selectively heating the surface of the base plate to the inside of a reaction chamber. CONSTITUTION:A silicon base plate 6 having a silicon oxide layer of several 100Angstrom  on a surface layer is held on a susceptor 7 in a reaction chamber 5. Gas for film formation is introduced into the reaction chamber 5 through an inlet 8 and discharged through on outlet 9, and ultraviolet laser beams 2 which are regulated to proper energy density by a cylindrical telescope 3 are passed parallel to the base plate 6 to photodissociate gas for film formation. On the other hand, pulse CO2 laser beams 11 having about 9.3mu wavelength which are emitted from a pulse CO2 laser oscillator 10 are projected on the base plate 6 via a reflecting mirror 12 and a window 13. Since pulse CO2 laser beams 11 are hardly absorbed by silicon and selectively absorbed only by silicon oxide, only the surface layer of the base plate 6 is heated. Thereby a thin film is formed in such a state that mean temp. of the base plate is maintained at room temp.

Filed: 1980-05-21
Abstract: PURPOSE: To perform seaming of canned cans smoothly at high speeds without requiring running-in by providing a clutch mechanism between the plate supporting table and the rotator of a lifter.  
     CONSTITUTION: When a motor is driven, a rotator 6 and a plate supporting table 4 are coupled by means of a clutch and therefore a lifter plate 2 rotates in the state that a can 1 is not grasped by a seaming chuck B. Next, when the chuck B moves downward and rotates while pressing the can 1, a lifter A sustains driving rotation. Next, when a lifter body 15 is moved upward by a cam 16, the rotator 6 also moves upward, and disconnects the clutch coupling of the rotator 6 and the table 4, then the table 4 becomes a free state and is rotated by the rotation of the chuck B. Upon completion of seaming, the lifter 15 moves downward and the rotator 6 and the table 4 are coupled by the clutch, thereby driving the lifter A to rotate.
