Title: Field effect transistor
Inventor: SHIMANOE TAKUJI
IPC: H01L29/80
Filed: 1981-12-21
Abstract: PURPOSE:To achieve a high withstand voltage and a high gain without yielding strain  in the interface between an operating layer and a buffer layer, by using a super lattice  structure comprising a semiconductor material, which is the same as that of the operating layer and a semiconductor material whose band gap is larger than that of the  former material, for the buffer layer. CONSTITUTION:A buffer layer 14, comprising an AlxGa1-xAs film 12 and a GaAs film  13, is provided. In this way, the leakage of carriers 8 can be prevented by the interface  between the operating layer 3 and the super lattice layer 14 and a barrier formed in  the buffer layer 14. The height of the barrier is changed by the number of the lattice of the buffer layer 14 and the film thickness of the GaAs film 13 and the AlxGa1-xAs  film. Furtheremore, by using the buffer layer 14 in the super lattice structure, strain  due to junction between different kinds can be prevented, and the degradation in crystal property of the operating layer 3 and the formation of interface traps between the  operating layer 3 and the buffer layer 14 are prevented. Therefore, the effect of the  prevention of the leakage of the carriers 8 to the buffer 14 is directly reflected to the  element characteristics, the high withstand voltage of the GaAs FET and the high gain  can be achieved, and high frequency characteristics can be improved.

Title: Image pickup device for object to be inspected
Inventor: OGASAWARA AKINOBU
IPC: G02B27/18
Filed: 1986-09-06
Abstract: PURPOSE:To pick up an image even if a body to be inspected shifts in position or varies in the distance from an optical axis by providing a 2nd convex lens which has a small diameter at the focus position of a 1st convex lens and arranging an image pickup element on the image formation plane of the body obtained by the composition of both lenses. CONSTITUTION:The interval (b) between the convex lenses 7 and 9 is set equal to the focal length of the lens 7. Further, the interval (c) between the lens 9 and image pickup element 4 is so set as to the image of the body to be inspected on the element 4. Further, the diameter of the lens 9 is about 1/5-1,500 times the diameter of the lens 7 where luminous flux 12 which is incident on the lens 7 and parallel to the optical axis 8 is only passed. Then the upper end of the body 1 to be inspected is image-formed 10 on the element only with parallel luminous flux 12 determined by the diameter of the lens 9 and distances (b) and (c). Then even if the body 1 shifts in position to 2, the luminous flux 12 only varies as shown by a dotted line and the position of the image formation 11 on the element has almost no change. Therefore, variation in optical power is extremely small within the movement range of the body 1 where the quantity of defocusing on the image formation surface 10 does not become not so large.
