Filed: 1990-02-02
Abstract: PURPOSE:To make it possible to form an insulating film having a superior buried flatness and to contrive to improve the yield of the manufacture of an integrated circuit device because the insulating film having the superior flatness can be formed by a process only of one time by a method wherein a deposited film in a fluid state is vapor-phase grown on the main surface of a semiconductor substrate at a substrate temperature equal to an higher than the glass transition temperature of the deposited film. CONSTITUTION:In the manufacturing process of a semiconductor device, wherein a deposited film 204 is formed for flattening a step of the main surface of a semiconductor substrate, the film 204 in a fluid state is vapor-phase grown on the main surface of the substrate using a substrate temperature of the glass transition temperature or higher of the film 204. For example, an insulating film 202 is formed on a single crystal silicon substrate 201 with an semiconductor element formed thereon and moreover, polycrystalline silicon wirings 203 are formed. Then, a vapor growth of a fluid BPSG film 204 is performed at a substrate temperature of 900 deg.C, at a pressure of 0.6 Torr, at the flow rate of 120SCCM of SiH4 gas, at the flow rate of 2 slm of N2O gas, at the flow rate of 10SCCM of PH3 gas and the flow rate of 10SCCM of B2H6 gas. Thereby, the formed film 204 becomes one having a flatness superior that of a conventional film obtainable by performing two processes of film formation and reflow.

Abstract: PURPOSE:To minimize the number of holes of the core bar and to obtain the equal seepage of the applying liquid by having the groove to extend in parallel to many shafts so that the core bar may divide the circumference to the outer circumference and opening the hole at the groove bottom. CONSTITUTION:For the cleaning roller, a core bar 1 has a groove IC to extend in parallel to many shafts such as a spline shaft at the outer circumference, and a hole 1a to cause an applying liquid of an internal part 1b to leak is opened at the bottom of a groove 1c.

Title: Method for estimating reflected light on surface of object
Inventor: OZEKI TORU
IPC: G01N21/55
Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To find proper reflected light close to a real physical phenomenon even when an incident direction and a light receiving direction are not located on the same plane. SOLUTION: A reflected light estimating method is performed by following processes. Namely, when the incident direction is fixed in a reference incident direction, concerning two-dimensional(2D) reflection including the light receiving direction in the incident direction, a reflectivity measured value R in the arbitrary light receiving direction is found (S1). An object incident direction L1 desired to know the reflectivity and an object light receiving direction L2 are set (S2 and S3). A virtual plane for applying the arranging relation of regular reflection to the directions L1 and L2 is found as an object virtual plane (S4). Concerning the 2D reflection, the similar virtual plane is estimated as well.  When the inclination level of this virtual plane is equal with the inclination of the object virtual plane, the reflectivity of 2D reflection is found from the measured value (S5-S7). The found reflectivity is equal with a reflectivity in the object light receiving direction L2.
