Title: Manufacture of semiconductor device
Inventor: INOUE FUMIHIKO
IPC: H01L29/78
Filed: 1988-03-24
Abstract: PURPOSE:To lengthen the lifetime of a tunnel oxide film by conducting an impurity doping into a floating gate on the tunnel oxide film by an ion implantation method using arsenic. CONSTITUTION:When the concentration of phosphorus is stabilized at a desired value, an ion implantation method is utilized, but the lifetime of a tunnel oxide film 4 is limited when phosphorus is used as a doping impurity. Consequently, the doping of the impurity to a floating gate 5 on the tunnel oxide film 4 is performed through the ion implantation method of arsenic. Accordingly, the floating gate into which the ions of arsenic are implanted is formed, thus making the lifetime of the tunnel oxide film 4 longer than the doping of phosphorus. The reliability of a ROM can be improved.

Abstract: PURPOSE:To prevent the infiltration of a water drop from the spacing between a holder and cap and to make improvement in the reliability of the sensor by widening the clearance between the stepped surface between the small-diameter part and large- diameter part on the base end side of the holder and the front end of the cap. CONSTITUTION:The distance of the clearance S between the stepped surface 10 of the large-diameter part of the holder 1 and the small-diameter part on the base end and the front end of the cap 5 is widened to, for example, about 3mm, and further, the angle of the stepped surface 10 with the small-diameter part on the base end side of the holder 1 is set at, for example, about 107 deg. to form the curved shape having a smooth angle part. The water drop is generally liable to be stuck to the clearance S by surface tension if the distance of the clearance S is small. The clearance S between the holder 1 and the cap 5 is, thereupon, widened, by which the sticking of the water drop between the stepped surface part 10 of the holder 1 and the front end of the cap 5 is prevented. The infiltration of the water drop into the sensor is prevented in this way and the degradation in the electromotive force of the sensor by the infiltration of the water drop into the sensor is prevented, by which the improvement in the reliability of the sensor is made.
