IPC: H01L29/84
Filed: 1992-11-26
Abstract: PURPOSE:To improve the accuracy and workability of the title sensor by forming N- or P-type areas on both the upper and lower surfaces of a P- or N-type silicon substrate by epitaxial growth or by sticking two wafers together and stopping etching by means of a PN junction. CONSTITUTION:P-type epitaxial layers 2 and 3 having thicknesses of about several mum are formed on both surfaces of a single-crystal N-type silicon substrate 1. The substrate 1 is photolithographically patterned and etching is stopped at the surface of the N-layer of the substrate 1 by applying potentials at which etching is advanced to the P-layers of the epitaxial layers 2 and 3 and another potential at which the etching is stopped to the N-layer in an alkali solution. Thus the gap between a fixed electrode and mobile electrode 10 is formed with high accuracy of sub-microns. Similarly, the mobile electrode 10, a cantilever 11, and the fixed electrodes of silicon substrates 4 and 5 are formed. Then the worked silicon substrates 4, 1, and 5 are piled up in a three- layer structure and jointed to each other by anodic connection or direct silicon connection.

IPC: G01N33/76
Filed: 1994-11-29
Abstract: PURPOSE: To enable the stable storage of a reagent by adding an effective amount of receptor activation inhibitor to the reagent containing estrogen receptor and progesteron receptor and protecting it at a low temperature by a netlike stabilization means. CONSTITUTION: About 1 to 5 millimol of, for example, sodium molybdophosphate, sodium vanadate, etc., is added as a connection section activation inhibitor to a reagent containing both of estrogen receptor and progesteron receptor. Moreover, the reagent contains a netlike stabilization means of saccharides. The concentration of approximately 0.05 to 0.4mol is effective for stabilization of high degree. Reduced saccharides become three- dimensional netlike tissue which holds molecules in a connection section, protect and prevent the molecules from being oxidized, and stabilize them while they are frozen and dried. Consequently, it is possible to obtain the stabilized reagent containing estrogen receptor and progesteron receptor.
