Filed: 1987-04-20
Abstract: PURPOSE:To improve breakdown strength and to prevent a narrow channel effect, by utilizing a side wall formed on the side of a protruding region, thereby forming channel stopper regions, and isolating the regions from an impurity region of an element forming region both the vertical and lateral directions. CONSTITUTION:A side wall 18 is formed on the side 15 of a protruding region 14. A source/drain region 22 of an element and channel stopper regions 19 are vertically isolated from step parts. Therefore, the defect that a breakdown voltage becomes low is prevented, and high breakdown strength is realized. A narrow channel effect is also prevented effectively. The channel stopper regions 19 are formed so that are laterally isolated from the side wall. The direct contact of the source/drain region 22 and the channel stopper regions 19 is prevented, and the decrease in breakdown strength is prevented. The narrow channel effect, in which the channel stopper regions 19 are expanded in the lateral direction and a threshold voltage value Vth becomes high, is effectively prevented together with the vertical isolation.

Title: Method and apparatus for monitoring cement kiln
Inventor: TAKENOUCHI TAKEYOSHI
IPC: F27B7/42
Filed: 1989-04-17
Abstract: PURPOSE:To control burning operation precisely and stably even for a cement kiln in an dusty atmosphere by measuring emitted light in the kiln, and using the change in intensity of alkali line spectrum as one of control variables. CONSTITUTION:Electrons in alkali atoms which are evaporated from a clinker 25 in a burning zone reach a high energy level from a ground state, emit corresponding light and return to the original state. The electronic energy in the alkali atoms in recovered air which is introduced into the kiln from a clinker cooler is in the ground state but absorbs light emitting energy. Thus a high energy level is obtained. When the inside of the kiln becomes a steady state, the intensity of the absorbing spectrum of the alkali under measurement becomes small. The change in alkali content in a raw material does not give effect on the absorbing intensity of the spectrum but gives effect on the spreading of the spectrum. Therefore, the burning state in the kiln can be monitored when the absorbing intensity of the ray spectrum is measured at the respective intrinsic position for the atoms of Na and K.
