Abstract
A semiconductor device comprising bolometers arranged in two-dimensional form corresponding to pixels for converting incoming infrared rays into electrical signals includes vertical switches, a vertical shift register, horizontal switches, and a horizontal shift register as means for selecting an arbitrary pixel. The semiconductor device is configured to allow an overcurrent to be supplied to a bolometer in a pixel selected by those means.
Claims7
A semiconductor device comprising:
- thin film resistors arranged in two-dimensional form corresponding to pixels for converting incoming infrared rays into electrical signals or for emitting infrared rays;
- and
- selecting means for selecting an arbitrary thin film resistor from said thin film resistors to supply an overcurrent to the selected thin film resistor.
A semiconductor device comprising:
- thin film resistors arranged in two-dimensional form corresponding to pixels for converting incoming infrared rays into electrical signals or for emitting infrared rays;
- a semiconductor switch provided to each of the thin film resistors;
- a signal line to which the thin film transistors is connected for each column;
- a first contact connected to the vertical signal line;
- and
- a second contact connected to a drain of the semiconductor switch;
- wherein the first contact is disposed close to said second contact in adjacent pixels in the column direction.
