Title: Vapor growth of compound semiconductor
Inventor: MANNOU MASAYA
IPC: H01L21/205
Filed: 1986-12-08
Abstract: PURPOSE:To obtain a high quality compound semiconductor layer which has a steep doping profile by controlling a conductive type and carrier concentration by controlling the concentration of the impurity in a nondoped compound semiconductor layer obtained at the supply ratio of two or more different transport raw materials used for one group V element. CONSTITUTION:When GaAs is epitaxially grown, e.g., TMGa for the transport raw material of group III element Ga and two kinds of AsH3 and trimethylarsenic (TMAs) for the transport raw materials of group V element As are used. In a GaAs layer grown by using the TMAs and the TMGa, a comparatively high concentration good p-type GaAs layer 3 can be obtained by incorporating carbon even without arbitrarily adding an impurity. This step easily provides a required conductive type or carrier concentration compound semiconductor layer and the crystallinity of the compound semiconductor layer is good. Further, no memory effect of a dopant represented by Zn exists and the profile of the concentration of the impurity is steep. Accordingly, a compound semiconductor laminated structure which has excellent element characteristics can be obtained.

Abstract: PURPOSE:To facilitate the monitoring of reaction by a method wherein, in order to perform the film formation process or the etching process of a substrate to be processed by leading-in reaction gas to be reacted by photoexciting process, the processed substrate is floated from a grounding potential while substrate current generated by loaded particles discharged from the substrate is measured to monitor the reaction. CONSTITUTION:A substrate S to be processed is irradiated with synchrotron radiation 3 to discharge loaded particles of electron ion by photoexciting so that any generated substrate current may be measured by a current detector 8. At this time, the current (i) is fluctuated by the existence of led-in reaction gas so that the in-process monitoring may be made feasible by observing said fluctuation. Accordingly, this processor is composed of a reaction chamber 1 for vapor deposition process, a beam line 2 leading the synchrotron radiation 3 from an accumulation ring not shown in figure, a substrate holder 4 holding the processed substrate S on an irradiating part in the chamber 1 and floating the substrate S from a grounding potential, a gas feeder 5 leading-in reaction gas 6, an exhaust system 7 and the current detector 8.
