Title: Light emitting element
Inventor: SAKAI SHIRO
IPC: H01L33/06
Filed: 2000-09-27
Abstract: PROBLEM TO BE SOLVED: To provide a light emitting element for ultraviolet rays which has superior light emission efficiency. SOLUTION: An N type AlGaN layer 12 is formed on a sapphire substrate 10 and an N type light emission layer 14 is formed thereupon; and a buffer layer 16 is formed thereupon and further a P type AlGaN layer is formed thereupon. The buffer layer has its electron density higher than the hole density of the P type AlGaN layer 18 and wider band gap energy than the N type light emission layer. Consequently, holes injected into the buffer layer 16 are more than electrons injected into the P type AlGaN layer 18 and the thickness of the buffer layer 16 is specified, so that the holes are injected into the N type light emission layer 14. Light emission is therefore caused in the N type light emission layer 14 with high light emission efficiency, so that the light emission efficiency of the light emitting element can be increased.

Title: Mos transistor
Inventor: TAKEMORI TOSHIYUKI
IPC: H01L29/78
Filed: 2000-09-28
Abstract: PROBLEM TO BE SOLVED: To provide a technology for reducing the continuity resistance of a power MOSFET. SOLUTION: Related to a power MOSFET1, when a first gate electrode 41 is applied with a voltage equal to or higher than a threshold, while a voltage is applied between a source region 36 and a main semiconductor layer 12 which is the drain, an inversion layer is formed at the interface between a first gate insulating film 95 formed on the side surface of a trench 22 and a body region 32, and a current flows from the main semiconductor layer 12 to the source region 36 through the inversion layer. A channel width of the MOS transistor 1 depends on the depth of the first gate electrode 41, and the deeper the first gate electrode 41 is the wider channel width becomes, resulting in a lower continuity resistance of the MOS transistor 1.  Thus, the continuity resistance is lowered by forming the first gate electrode 41 deeper, without enlarging the occupancy area, so that the continuity resistance can be made lower than before.
