Abstract:
The present invention relates to a sustained release film formulation for healing wound comprising epidermal growth factor, chitosan, viscosity modifiers, plasticizers, and stabilizers. Specifically, the present invention relates to a sustained release film formulation for healing wound comprising epidermal growth factor as an effective ingredient and chitosan as a main base, and additionally comprising one or more antioxidants selected from the group consisting of EDTA and vitamin C; one or more viscosity modifiers selected from the group consisting of hydroxypropylmethylcellulose, gellan gum and pullulan; and one or more plasticizers selected from the group consisting of glycerin, propylene glycol, polyethylene glycol, polyvinyl alcohol and polyvinylpyrrolidone thereto. When the present film is attached to wound site, it absorbs exudation from wound site, and so is changed to hydrogel to keep wound site humid, which is good for wound-healing. And, the present film has superior attachment property to human body, and antifungal activity. Thus, the present film has more merits than simple ointment/cream formulation.

Abstract:
A submicron level dimension reference for use with a scanning electron microscope in a semiconductor device fabrication apparatus. The reference has a first insulating layer with a first pattern formed on a semiconductor wafer substrate. A plurality of contacts are formed between the first pattern of the first insulating layer such that the contacts directly communicate the wafer substrate. The contacts are capable of carrying an electrical charge. An electrically conductive layer is formed over the contacts and the first insulating layer. A second insulating layer with a second pattern is formed over the conductive layer. Electrical charges generated by radiating the scanning electron microscope on the submicron level dimension reference are transferred from the first and second insulating layers to the wafer substrate via the conductive layer and the plurality of contacts.
Abstract:
A film thickness standard (FTS) comprises an oxide film formed on a semiconductor substrate with a thickness over 1 .mu.m. A method of preparing an oxide film thickness standard reference of semiconductor device is carried out by repeatedly and continuously performing the formation process of the oxide film under the same processing conditions thereby to form the oxide film on a semiconductor substrate with a thickness over a certain level.
Abstract:
A method for testing a contact opening of a semiconductor device includes the steps of: inspecting a wafer using an in-line scanning electron microscope, comparing a contrast difference of contact opening regions displayed on the scanning electron microscope, and determining whether the processes for forming the contact openings have been performed correctly based on results of the comparison step. The test method may be performed after any of a contact photolithography process, contact etching process, or conductive layer etching process.

A block studying tool for an infant, includes: a block body having a hexahedral shape, a lower portion of which is opened; and a plurality of unit assembling portions disposed to protrude from an upper portion of the block body upward and disposed to be spaced a predetermined distance apart from each other, wherein a divider is disposed at an inside of the lower portion of the block body and forms an assembling space in which the plurality of unit assembling portions of the adjacent block body are to be assembled according to positions.
Abstract:
A method of measuring a step height of a device using a scanning electron microscope (SEM), the method may include providing a device which comprises a first region and a second region, wherein a step is formed between the first region and the second region, obtaining a SEM image of the device by photographing the device using a SEM, wherein the SEM image comprises a first SEM image region for the first region and a second SEM image region for the second region, converting the SEM image into a gray-level histogram and calculating a first peak value related to the first SEM image region and a second peak value related to the second SEM image region, wherein the first peak value and the second peak value are repeatedly calculated by varying a focal length of the SEM, and determining a height of the step by analyzing a trend of changes in the first peak value according to changes in the focal length and a trend of changes in the second peak value according to the changes in the focal length.
Abstract:
The present invention relates to a side curtain airbag and an airbag system comprising the same. The side curtain airbag according to the present invention comprises an inflating part having gas inflatability, a non-inflating part supporting the inflating part, and an adhered part constituting a boundary between the inflating part and the non-inflating part. The adhered part is coated with a seam sealant and sewed. The initial maximum pressure of the inflating part is 40 KPa or more when injecting a gas therein with an instant pressure of at least 10 bar, and the pressure after 6 seconds is 25 KPa or more.The side curtain airbag according to the present invention optimizes to apply the method of seam sealant coating and sewing on the adhered part constituting a boundary between the inflating part and the non-inflating part. Thus, it can keep the internal gas pressure of the airbag to the extent of protecting passengers safely at rollover.
