Title: Semiconductor device
Inventor: YAMAGISHI HIDETAKA
IPC: G03F9/00
Filed: 1985-11-29
Abstract: PURPOSE:To prevent a decrease in detection precision and centering precision to form fine and highly dense elements, by detecting a centering pattern through an oxidizing film having high transparency, for position detection. CONSTITUTION:A stepper is utilized for an epitaxial growth layer 4 to perform formation of an element, and a prescribed element pattern of a bipolar transistor or the like is formed. In this semiconductor device, because a centering pattern 3 can be observed through an oxidizing film 5 having high transparency from a surface side of the semiconductor device, laser light or the like is directly projected to the centering pattern 3 through the oxidizing film 5 when centering is performed by stepper. And, position detection is performed by detecting the light reflecting on a step-difference part (an edge part) of the centering pattern 3. Therefore, this direct detection of the centering pattern 3 enables centering of high precision to be performed and fine and highly dense elements to be formed without occurrence of detection shift caused by pattern-distortion and step-difference alleviation in the epitaxial growth layer.

IPC: G06T7/00
Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To derive the precise correction of dislocation with the change of the evaluation value of a matching degree is large by correcting the dislocation of a reference picture and an inspection picture by means of a pixel string having more than prescribed outline intensity and the prescribed number of strings. SOLUTION: The outline strength of the reference picture is calculated and the number of the pixels having the outline intensity of more than prescribed intensity is counted for the respective pixels in the direction so as to obtain the number of the pixels. The pixel string whose number of the pixels is more than the prescribed one is set to be the pixel string which can be selected. The absolute value of the differences for the respective pixels between one objective pixel string and the pixel string obtained by shifting it by the prescribed pixels is calculated. The absolute value is compared with the pixel value of the corresponding pixel of the outline picture constituted of the outline of the reference picture.  Since the absolute value of the differences has the pixel exceeding the pixel value of the pixel of the outline picture, the objective pixel string is judged that where a pattern is not constituted of only repetitive components. Thus, the precise dislocation correction value can be detected.
