Abstract
A charge transfer device formed in a semiconductor substrate and including an array of electrodes distributed in rows and columns, wherein: each electrode is formed in a cavity with insulated walls formed of a groove which generally extends in the row direction, having a first end closer to an upper row and a second end closer to a lower row; and the electrodes of two adjacent rows are symmetrical with respect to a plane orthogonal to the sensor and comprising the direction of a row.

A multidirectional two-phase charge transfer device formed in a semiconductor substrate and comprising an array of electrodes distributed in rows and columns, wherein:
- each electrode is formed exclusively in a cavity with insulated walls formed of a groove which generally extends in the row direction, having a first end closer to an upper row and a second end closer to a lower row;
- and
- the electrodes of two adjacent rows are symmetrical with respect to a plane orthogonal to a surface of the semiconductor substrate and extending along a line midway between the two adjacent rows.
