I claim:
1. An image sensor comprising:
a plurality of pixels formed in a semiconductor substrate, each pixel including a light sensitive element;
a multilayer stack formed over said plurality of pixels, said multilayer stack adapted to filter incident light in the infrared region;
a plurality of micro-lenses formed over said multilayer stack and over said light sensitive element.
2. The image sensor of claim 1 further including a color filter formed over each pixel, said color filter formed between said micro-lens and said multilayer stack.
3. The image sensor of claim 1 further including a color filter formed over each pixel, said color filter formed over said micro-lens.
4. The image sensor of claim 1 wherein the multilayer stack comprise pairs of titanium oxidesilicon dioxide thin films.
5. The image sensor of claim 4 wherein said multilayer stack comprise 6 to 8 pairs of titanium oxidesilicon dioxide thin films.
6. The image sensor of claim 4 wherein each thin film is approximately 200 nm thick.
7. A pixel of an image sensor comprising:
a light sensitive element formed in a semiconductor substrate;
a multilayer stack formed over light sensitive element, said multilayer stack adapted to filter incident light in the infrared region;
a micro-lens formed over said multilayer stack and over said light sensitive element.
8. The pixel of claim 7 further including a color filter formed between said micro-lens and said multilayer stack.
9. The pixel of claim 7 further including a color filter formed over said micro-lens.
10. The pixel of claim 7 wherein the multilayer stack comprise pairs of titanium oxidesilicon dioxide thin films.
11. The pixel of claim 10 wherein said multilayer stack comprise 6 to 8 pairs of titanium oxidesilicon dioxide thin films.
12. The pixel of claim 10 wherein each thin film is approximately 175 nm thick.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method for controlling distribution of network communications via a communications network, the method comprising:
tracking a number of inbound connections for each of a plurality of communications hosts;
sending, responsive to a certain communications host accounting for a number of inbound connections exceeding a certain percentage of available connections, a request to the certain communications host to reduce its network communications;
monitoring a volume of network communications from the certain communications host; and
altering, responsive to the certain communications host failing to reduce a volume of its network communications, a connection build process for the certain communications host to control a flow of the certain communications host’s network communications;
2. The method of claim 1, wherein the connection build process relates to a TCP connection.
3. The method of claim 1, wherein the connection build process relates to an SMTP connection.
4. The method of claim 1, wherein the connection build process comprises slowing the connection build process for said certain host.
5. The method of claim 1, wherein altering the connection build process comprises stopping the connection build process for said certain host.
