Title: Apparatus for vapor phase epitaxial growth
Inventor: MIKAMI MASAO
IPC: H01F41/22
Filed: 1978-07-18
Abstract: PURPOSE: To obtain the uniform depth of the oxide epitaxial layer by introducing the material vapor and oxygen gas into the growing chamber and colliding them at the same time.  
     CONSTITUTION: In a growing chamber 14 located is a substrate holder 16, on which a monocrystal wafer 15 is laid. High volatile chemical compounds 11 and 12 consisted of the desired component element are located in a materials chamber 13 and the vapor produced by heating and evaporating them is introduced into the growing chamber 14 through a bypassing pipe 18 with carriergas. This materials vapor collides head-on against hydrogen gas introduced through a hydrogen transporting tube 17 at their injection point in the growing chamber 14. This causes a turbulent flow where the materials vapor and the hydrogen gas are mixed uniformly and the turbulent flow is sent to the downstream to develop the growth of the epitaxial layer on the monocrystal wafer 15. This enables to obtain the oxide epitaxial layer having uniform depth in wider area.

An address converter 2 retrieves the page table 3 according to the page number of the virtual page. When the page is correspondent to the page of a physical space, offset is synthesized with the page of the physical space and the physical address is generated. When the page is not correspondent, interruption is generated in a CPU 1. Thus, a procedure for accessing the graphic VRAM can be processed without being conscious of switching the picture of the graphic VRAM.
