Title: Growth method for semiconductor thin-film comprising dope layer
Inventor: TAKAHASHI KUNIMASA
IPC: H01L21/205
Filed: 1999-09-06
Abstract: PROBLEM TO BE SOLVED: To grow a semiconductor thin-film comprising pn junction of abrupt profile by, during growth of a thin-film on a base material set in the space within a reactive furnace, supplying impurity such as doping gas into the reactive furnace while changing the supply amount of at least one kind of material gas. SOLUTION: Nitrogen is supplied as an n-type impurity doping gas 12 to form an n-type dope layer on an undope layer. With the flow rate of the hydrogen gas of diluted gas 11 as well as silane gas of material gas 8 kept constant, the nitrogen of doping gas 12 is supplied while the flow rate of propane gas of material gas 7 is reduced by controlling a flow meter 1, to form an n-type dope layer. When the flow rate of propane gas of material gas 7 is reduced while that of nitrogen gas U impurity doping gas 11 is kept constant, a carrier density increases. As a result, taking-in of nitrogen in a silicon carbide thin-film is controlled only by changing the flow-rate ratio between propane gas and silane gas of material gas.
