Title: Manufacture of semiconductor device
Inventor: SOTOZONO AKIRA
IPC: H01L21/205
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To prevent the formation of a facet and an unnecessary cavity and the generation of roughness through a relatively simple process by selectively growing silicon under the supplying speed control condition and then forming a silicon film under the reaction speed control condition. SOLUTION: Single crystal silicon is grown under the supplying speed control condition that the temperature is relatively low and not higher than 700 deg.C. Further, selective epitaxial growth of the silicon is carried out under the reaction speed control condition that the temperature is high and not lower than 800 deg.C. In the second SEG, the formation of an epitaxial silicon film 12 under the reaction speed control condition is realized only in the part where the silicon is exposed, i.e. only on the gate electrode and on the diffusion layer with good selectivity. Under the reaction speed control condition, simultaneous etching takes place too so that the silicon grains 15 formed on the element isolating insulating film 2 and the silicon nitride side wall 10 in the initial silicon growth are etched.  Further, because the side wall is silicon nitride having high wettability with respect to silicon, an epitaxial silicon film is formed without a facet.

Abstract: PURPOSE:To obtain an ice block where foreign matter is uniformly distributed, well balanced by previously uniformly disposing ice and foreign matter by mixing the foreign mutter into granular ice and stirring the same, and thereafter again making the granular ice in which the foreign matter is mixed. CONSTITUTION:Granular ice 1 in which gold foil is mixed and uniformly distributed is introduced into an ice making can 2, and water is gradually poured from the bottom of the can to the upper portion of the can 2 using a pipe 3 extending from the upper portion of the can to the vicinity of the bottom of the same such that spaces among the granular ice pieces are filled with water.
