Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To enable a level to freely set gradients and measure the gradients by widening the usable range of the block by attaching a gauge which can be put in and out from the block to one side of the block. SOLUTION: An insertable/removable gauge 2 is attached to one side of a level 1 with a ball nut 3. At the time of using the level 1, a gradient is set by taking out the gauge 2 and the gauge 2 is fixed with the ball nut 3.

Abstract: PURPOSE:To prevent a blooming phenomenon and a color mixing phenomenon by forming a prescribed density gradient from the surface of an Si substrate in the thickness direction. CONSTITUTION:On an n type Si substrate 16, an oxide film 17 is formed, through which acceptor ions (e.g., boron) are implanted and then diffused by a high-temperature treatment in an atmoshere of inert gas (e.g., N2); and boron ions are further implanted and thermal diffusion is carried out. The said processes are repeated several times. Then, the dosage of the ion implantation and the time of diffusion are so determined that a p layer 18 formed on the substrate 16 has density variations of impurities, as shown in the figure, from a p-layer surface point B in the depth direction (directon A-A') to a boundary point B' between the substrate 16 and p layer 18. On the substrate 16 and layer 18, an n layer 2 as a photosensitive part, an n layer 3 as a channel, etc., are formed. Then, signal charge generated in the Si substrate at a deeper point than the n layer as the photosensitive part is never diffused to the substrate surface in the surface direction, so that a blooming phenomenon, etc., never occur.
