IPC: C12N9/96
Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To obtain the subject solution useful for e.g. assays making use of immunoreaction in the clinical examination and diagnostic field, by adding a specific carboxylic acid compound bearing hydroxyl-substituted phenyl group to a solution having peroxidase activity.

Title: Solid-state image pickup device and manufacture thereof
Inventor: YAMADA TAKAHIRO
IPC: H04N5/335
Filed: 1985-04-09
Abstract: PURPOSE:To obtain the high transfer efficiency of signal charges even in a microcurrent region and low-noise characteristics and excellent transient characteristics by making an M-S contact constituting a signal transmission line use for a solid-state image pickup device to satisfy the conditions of a band gap and a closure and forming a semiconductor as a perfect crystal through hetero-epitaxy. CONSTITUTION:Signal charges formed by optical irradiation are stored in an N<+> region 111. When a vertical MOS switch 103 selected by pulses from a vertical scanning circuit 101 during a horizontal retrace line period is turned ON, signal charges in the N<+> region 111 transfer to the N<+> region 112 side. Since a compound region 115 (MSi2) adjacent to the N<+> region 112 is shaped through hetero-epitaxial growth, a forbidden band disappears in the vicinity of the surface of the N<+> region 112 by the effects of a band gap and a closure, and a surface level does not also exist, thus forming an ideal resistive contact. Since the signal charges of the N<+> region 112 easily transfer to a metallic wiring 113, the signal charges reach to an equilibrium state with charges existing in other N<+> regions 112 and N<+> regions 116, 112, etc.
