Patent number: 11929378Abstract: A light detection device includes: a back-illuminated light receiving element; a circuit element; a connection member; an underfill; and a light shielding mask. The light shielding mask includes a frame having an opening and a light shielding layer formed on an inner surface of the opening. A first opening edge on the side of the circuit element in the opening is located at the outside of an outer edge of the light receiving element. A second opening edge opposite to the circuit element in the opening is located at the inside of the outer edge of the light receiving element. The opening is narrowed from the first opening edge toward the second opening edge. A width of the frame increases from the first opening edge toward the second opening edge. The underfill reaches a gap between the light receiving element and the light shielding layer.Type: GrantFiled: March 13, 2023Date of Patent: March 12, 2024Assignee: HAMAMATSU PHOTONICS K.K.Inventors: Nao Inoue, Ryosuke Koike, Haruyuki Nakayama

Patent number: 6609232Abstract: In logical compound of inter-subblock paths, circuits including all inter-subblock paths are generated. Logical compound is conducted for the generated circuits to achieve logical compound of the inter-subblock paths. By treating inter-subblock paths as intra-subblock paths, no input/output delay restriction is required for the logical compound of inter-subblock paths. This makes it possible to fully use performance of the logical compound tool, and hence the inter-subblock paths can be optimized through one operation of the processing.Type: GrantFiled: February 26, 2001Date of Patent: August 19, 2003Assignee: Hitachi, Ltd.Inventors: Teppei Hirotsu, Ryo Fujita, Kotaro Shimamura, Hiromichi Yamada, Dai Fujii, Haruyuki Nakayama
