IPC: C23C14/56
Filed: 1983-04-28
Abstract: PURPOSE:To provide a vapor deposition device of a multiple chamber type which prevents the ferromagnetic metal evaporated near the ends of partition plates for separating a vapor deposition chamber into multiple chambers from affecting the magnetic characteristic of said metal and permits easy removal of such magnetic metal by attaching freely attachable and detachable magnets to said ends. CONSTITUTION:The ferromagnetic metal evaporated from an evaporating source 9 sticks on a base body 4 mainly in the place of a can 7. The remaining ferromagnetic metal sticks on partition plates 2a and 2b, but particularly the ferromagnetic metal sticking near magnets 11a and 11b such as the gaps between the magnets 11, 11b and the can 7. The intrusion of the ferromagnetic metal into the 1st chamber 6 is therefore obviated and the sticking of the ferromagnetic metal on the body 4 of the vapor deposition surface wound around a feed roller 3 is prevented. Since the magnets 11a and 11b are made freely attachable and detachable, the easy removal of the excess ferromagnetic metal is made possible by removing the plated 2a and 2b.

Title: Method and apparatus for measuring wafer thickness for wafer lapping machine
Inventor: SHIMURA TAKASHI
IPC: G01B5/00
Filed: 1980-06-06
Abstract: PURPOSE:To make it possible to directly measure the thickness of each wafer in a carrier without moving the upper lapping surface plate up and down, by such constitution that a portion of each wafer which moves in a planetary manner on the  surface of a lapping surface plate projects from the lapping surface plate. CONSTITUTION:For example, carriers 4 on the lower lapping surface plate of a 4- way lapping machine move in a planetary manner through a sun gear 2 and an internal gear 3. When the lapping of wafers 5 in the carriers 4 has properly progressed and one of the carriers 4 reaches a measuring position 7, the movement is stopped and changed over so that the carrier 4 rotates on its own axis. A hole 9 provided in the carrier is detected by using a photosensor, and the rotation 8 is stopped at such a position that a wafer 5 projects from the surface plate 1. A moving arm 13 is moved 14 and inserted into the measuring position. Then, both sides of the wafer 5 are washed by using the water jetting out from a washing nozzle 12 and air, and the thickness of the wafer 5 is measured by using measuring gauge 1. Accordingly, the thickness of each wafer 5 in the carrier 4 can be directly measured without moving the upper lapping surface plate vertically.
