IPC: H01L27/14
Filed: 1998-10-19
Abstract: PROBLEM TO BE SOLVED: To obtain image information which can reproduce a high-contrast image by forming a layer which contains chromium oxide as the base layer of a light shield layer, and patterning the layer in a specific shape and obtaining the light shield layer. SOLUTION: As the layer on which the light shield layer is based, the layer containing chromium oxide is formed by sputtering. In this case, a sputter target consisting of chromium is used and the ratio of an O2 flow rate in an atmospheric gas flow rate is gradually decreased from the start to the end of film formation. At this time, the rate of the O2 flow rate is so selected that the light shield layer can finally be formed which is higher in oxidation degree on the end surface on a light-transmissive substrate side than on the other end surface facing the end surface. Namely, the 'base layer of the light shield layer' is formed by making the oxidation degree of chromium oxide of the 'base layer of the light shield layer' larger on the end surface on the light- transmissive substrate side than on the other end surface facing the end surface.

Abstract: PURPOSE:To prevent thermal breakdown in P-N junction by generating a breakdown phenomenon at a voltage lower than the breakdown voltage of a high breakdown-strength element at a uniform P-N plane junction, and making an overcurrent flow through the entire surface of the P-N plane junction. CONSTITUTION:N-type impurity ions are implanted between P-well layers 2. An N-diffused layer 5 is formed by thermal diffusion.

A high breakdown-strength element wherein the metal layer is a drain electrode 11 is formed. The potential of an N<-> type semiconductor substrate 1 is fixed to a source potential with an N<+> diffused layer 8. The impurity concentration of the N-type diffused layer 5 is determined so that the breakdown voltage of a P-N plane junction that is formed with the P<+> diffused layer 7 and the N-type diffused layer 5 is lower than the breakdown strength of the high breakdown-strength element. When a reverse bias is applied to a source electrode 12 and the drain electrode 11, a uniform breakdown phenomenon occurs at the P-N plane junction 13, and overcurrent flow through the entire plane.
