Title: Manufacture of semiconductor device
Inventor: OKABAYASHI TAKEKI
IPC: H01L21/225
Filed: 1990-05-22
Abstract: PURPOSE:To enable scattering of a relatively long backward recovery time to be reduced by adjusting temperature-increase speed when increasing temperature of a semiconductor substrate to a diffusion temperature for controlling life time of the semiconductor substrate. CONSTITUTION:An impurity source 4 is coated on other surface of an n-type silicon substrate 1 where an n<+> surface 2 is formed on one surface by spin coating. This substrate is fitted into a diffusion furnace as it is without performing prebaking. Temperature of the diffusion furnace is increased to a diffusion temperature 13, for example 1-2 deg.C /min. Then, when the diffusion temperature 13 is reached, the remaining carbon starts to be diffused first and then boron starts to be diffused. After a specified diffusion time, the temperature of the diffusion furnace is reduced and the silicon substrate is taken out at a take-out temperature, thus enabling backward recovery time of a diode to be reduced and the time to be controlled by the temperature-increase speed.

Filed: 1983-07-20
Abstract: PURPOSE:To transfer bottles stably between conveyors or between a dead plate and conveyor without tilting for any conveyor speed by pressing the bottle mouth with a member moving with same speed as the conveyor. CONSTITUTION:When transferring a bottle 50 onto a conveyor 3 through a star wheel 1, a cam 15 will push down a roller follower 14 while move a frame 10 upward and lift a belt 11' stretched over the frame 10 as a press member 11 higher than the bottle mouth 51. Here, the frame 10 will move up and down intermittently while synchronizing with the bottle 50. Consequently, immediately after transfer onto the conveyor 3, the bottle 50 will move downward to press the bottle mouth 51 resiliently with the belt 11' thus to prevent tilting of the bottle 50. Thereafter, the conveyor 3 and the press member 11 moving with same speed as conveyor 3 will hold the bottle mouth 51 thus to advance the bottle 50 smoothly onto the conveyor 3 without tilting.
