US Patent:

6373122, Apr 16, 2002

Filed:

Apr 12, 1999

Appl. No.:

09/290495

Inventors:

Massimo Antonio Sivilotti - Sierra Madre CA
John Edward Tanner - Pasadena CA
Jin Luo - Monrovia CA

Assignee:

Tanner Research, Inc. - Pasadena CA

International Classification:

H01L 23544

US Classification:

257620, 257202

Abstract:

Effective passivation structures and guard rings can be formed in borderless gate arrays by forming the gates in an array of discrete blocks separated by thin scribe lines in which the substrate is not covered by gates. Diffusions for guard rings can be formed in the substrate for guard ring purposes, and passivation structures can be sealingly attached to the substrate. Various circuit metalizations such as discrete layers or different circuits can be produced with a single mask by covering all but a selected portion of the mask during exposure.

International Classification:

G01V 904

US Classification:

Abstract:

An optical mouse utilizing a linear array of photodiodes is provided with circuitry to correlate during each self-timed cycle a new image with a stored image from the previous cycle with the new image offset relative to the stored image one pixel (photodiode signal) to the right, one pixel to the left, and also with no offset. All three correlations are done at the same time in separate correlators. Decision as to motion to the right, to the left or no motion is made on the basis of maximum correlation output. The new image is not stored in a second store array for use during the next cycle until any motion is detected, but it is stored in a first store array during the cycle when half the precharged photodiodes discharge below a predetermined level in response to incident light. A new cycle is initiated by precharging the photodiodes when any decision of motion or no motion is made.
