Title: Photodetector device with built-in circuit
Inventor: YAMAMOTO MOTOHIKO
IPC: H01L27/14
Filed: 1989-04-13
Abstract: PURPOSE:To increase photosensitivity of a photodetector device and hence make a response speed high by constructing the photo-detector element including an anode reaching an N-type thick, high specific resistance epitaxial layer penetrating an N-type thin, low specific resistance epitaxial layer. CONSTITUTION:For a photodiode part A, an N-type high specific resistance epitaxial layer 9 is formed to be thick on an N-type burried diffusion layer 2 burried in a P-type semiconductor substrate 1, on which an N-type low specific resistance epitaxial layer 11 is laminated to be thin. Further, a P-type diffusion layer 3-1 for a node reaching the lower N-type high specific resistance epitaxial layer 9 from part of the surface of said N-type low specific resistance epitaxial layer is provided. With such structure, the photodiode part N-type epitaxial layers 9, 11 effectively forms the lower thick N-type high specific resistance epitaxial layer 9. Hereby, photosensitivity of the photodiode is improved together with a response speed.

Abstract: PURPOSE:To provide the large-diameter macrolens which have aberrations compensated excellently from an infinite distance to a short distance corresponding to unmagnification by composing the lens of a front group which has at least one negative lens in a 2nd positive lens group and a rear group which has positive refracting power. CONSTITUTION:This lens capable of short-distance photography has a 1st lens group G1 with positive refracting power, the 2nd lens group G2 with positive refracting power, and a 3rd lens group G3 with negative refracting power in order from the object side. The 1st lens group G1 has at least one negative lens and the 2nd lens group G2 consists of a front group G2a having at least one negative lens and a rear group G2b having a positive refractive index. For focusing from an infinite distance to a short distance, the front group G2a of the 2nd group and the rear group G2b with the positive refractive index are moved to the object side so that their interval is larger in short-distance focusing than in infinite-distance focusing. In this constitution, a spherical aberration which is overcompensated with a larger diameter can be set excellently in a short-distance state of almost life size.
