Title: Substrate conveyor
Inventor: SHINKAI HIROSHI
IPC: H01L21/677
Filed: 1986-03-19
Abstract: PURPOSE:To quickly peel off a substrate from an absorbing member without being inflicted with an ill effect that dust or the like sticks to the substrate by providing a pressing member for peeling off the substrate on a substrate conveyor. CONSTITUTION:When a substrate 8 is closely stuck to the suction face of an absorbing member 2, the substrate 8 is pressed to the adsorbing member 2 by the atmospheric pressure P, and a vacuum chamber 11 is formed. In this case, no air is practically exists in the vacuum chamber 11 and an air stream 9 disappears, thus a push rod 4 is lowered until it is brought into contact with the substrate 8, and an energizing force F by a spring 5 is applied to the substrate 8 in the direction to remove the substrate from the adsorbing member 2. If the energizing force F is preset as atmospheric pressure P > energizing force F, the substrate 8 can be held without being peeled off from the adsorbing member 2. Under this condition, if a conveying arm 1 is driven, the substrate 8 can be conveyed. After the conveyance is completed, and suction passage 7 is atmospherically released, thus the substrate 8 is pushed by the energizing force F and is quickly peeled off from the adsorbing member 2.

Abstract: PURPOSE:To enable to accomplish a high speed and high density semiconductor device by a method wherein each semiconductor layer is continuously formed on a semiconductor substrate by performing a molecular beam epitaxial method. CONSTITUTION:A B<+>-doped P type base layer 15, an As-doped N type emitter layer 16, and a polycrystalline Si layer or an amorphous Si are grown on the P type semiconductor substrate 11, whereon an N<+> type buried layer 12, a P type channel-stopper 13 and an N-type collector layer 14 are formed, by performing a molecular beam epitaxial method.

Also, the layer 15 can be formed thin in thickness by utilizing the molecular beam epitaxial method. Also, the layer 16 of high density can be uniformly grown. As said layers 15 and 16 are grown independently, the compensating effect of donor and acceptor in emitter does not generate at all, thereby enabling to form a thin emitter junction and a base junction in an excellent manner and to contrive formation of a high-speed transistor.
