Title: Bio-sensor integrating CMOS integrated circuit - prepd. by insulating sensor area from circuitry on chip, forming gate oxide dielectric layer, etching using poly:silicon@ layer, etc.
Inventor: HEIN PETER DIPL ING
IPC: G01N27/414
Filed: 1991-05-10
Abstract: The biosensor consists of an ion sensitive field effect transistor (ISFET) and a biological or biochemical membrane using poly-Si construction which is surrounded by a housing. The sensor is made by insulating the sensor area from the rest of the circuitry on the chip by field-oxide regions (4); forming a gate oxide dielectric layer (5) then depositing a nitride layer over the oxide including the field-oxide regions, followed by etching a poly-Si layer (7) into a pattern; forming source/drain regions (24,25), and the baring active gate region of the ISFET by etching away the poly-Si layer from the active gate/drain/source regions and the field-oxide regions of the sensor area (10). The ISFET is assembled inside a housing (23) with the active gate region (10) inside a window (22) of the housing. The biochemical/biological membrane is placed on the active gate region. The drain/source regions (24,25) are connected to active circuitry inside the housing by diffused tracks (26,27) and contacted (28,29) by Al-tracks there. The detector circuitry is completed by etching contact windows and depositing and defining an Al-pattern. USE/ADVANTAGE - The device integrates a CMOS integrated circuit with the bio-sensor, which gives the advantage of improved threshold and gain control as well as improved stability compared with currently available Al-gate transistor based devices. The sensor area has a flat surface, which reduces the danger of ripping of a membrane applied to this area. The sensor device and detector circuitry are matched, reducing noise effects.

Title: Multi-spectral image recorder with image scanner - has narrow band spectral filters, with middle wavelengths distributed over entire visible range
Inventor: HILL BERNHARD PROF DR ING
IPC: H04N1/401
Filed: 1991-06-13
Abstract: A drum scanner has an opto-electronic detector and a CCD line scanner, or semiconductor surface sensor.
