PURPOSE: To ensure the positioning of a solid-state image pickup element with high accuracy, by putting a reference mark on a pellet to set the center of an array of picture elements within the pellet at a reference hole of a package.
CONSTITUTION: A positioning reference mark 7 consisting of an aluminum pattern 5 having nearly a square form and an organic color pattern 6 having a cruciform shape on its upper surface is provided at a part outside a picture element forming region formed on a pellet 1. A light transmissive protecting film 8 is coated on the surface of the mark 7. In this case, the pattern 5 is formed at the same time when a wiring pattern is formed on a wafer by an aluminum vapor deposition process. While the pattern 6 is formed at the same time when an organic color filter is formed on a picture element forming surface. A positioning pin is provided when a solid-state image pickup element is attached to a TV camera. Thus it is possible to perform an automatic position control between the camera optical axis and the center axis of the pellet picture element.
