Title: Manufacture of group iii nitride compound semiconductor element
Inventor: KAMIMURA TOSHIYA
IPC: H01L33/56
Filed: 1999-12-22
Abstract: PROBLEM TO BE SOLVED: To increase the productivity of a semiconductor element made of a group III nitride compound semiconductor by applying and hardening sealing resin on the electrode formed side of a substrate and then dividing the substrate into individual elements. SOLUTION: A buffer layer 102 is formed on a sapphire substrate 101 and then a high carrier density n+ layer 103 and a light emitting layer 104 of a multiple quantum well structure are formed on the buffer layer 102. On the light emitting layer 104, P type layers 105, 106 are stacked. Then, a multiple thick film electrode 102 is formed by evaporation of metal on the P type layer 106 and a negative electrode 140 is formed on the n+ layer 103. Between the electrodes 120 and 140, an SiO2 protective film 130 is formed. In an element having a layer made of a group III nitride compound semiconductor formed on a substrate, a positive and a negative electrode are formed on the same side of the substrate and therefore sealing resin is only applied on one side where the positive and the negative electrode are formed.  A group III nitride compound semiconductor element 100 has its electrode section resin-sealed and therefore the productivity of a flip-chip type semiconductor element having a high stability and durability can be increased.

IPC: G01S13/93
Filed: 1998-12-28
Abstract: PROBLEM TO BE SOLVED: To improve the detection accuracy of radar equipment for the direction of an object by eliminating the component by means of a side lobe as an unnecessary component. SOLUTION: A processor calculates the component of a received signal detected by means of a main lobe only by subtracting the calculated component by means of a side lobe from the signals received through transmission-reception channels. After the subtraction of the component by means of the side lobe from the received signals, the received signals exceeding a threshold α are those at the levels L3, L4, and L5 of transmission-reception channels #3, #4, and #5 and the weighted mean value θ of the received signals is calculated from a formula θ=(L3θ3+L4θ4+L5θ5)/(L3+L4+L5). The weighted mean value θcalculated from the formula becomes a value closer to an angle θ4 between angles θ4 and q15 and also closer to the position of the object in Fig. 1A.
