A process of manufacturing a semiconductor device includes the steps of forming a stacked structure of a first III-V compound semiconductor layer containing In and having a composition different from InP and a second III-V compound semiconductor layer containing In. The second III-V compound semiconductor layer is formed over the first III-V compound semiconductor layer and growing an InP layer at regions adjacent the stacked structure to form a stepped structure of InP. The process further includes the step of wet-etching the stepped structure and the second III-V compound semiconductor layer using an etchant containing hydrochloric acid and acetic acid to remove at least the second III-V compound semiconductor layer.
摘要:
The invention relates to the preparation of oyster flesh extracts. Raw oyster flesh is placed in an extractor with a solution stored in it. The extractor is closed up tight and subjected to a reduced pressure to extract oyster flesh extracts from the raw oyster flesh, and they are fed into the solution in the extractor. An extraction solution with the oyster flesh extracts fed in it is concentrated. An alcohol solution is added to the concentrated solution to precipitate out the oyster flesh extracts. The precipitates are dried into dry oyster flesh extracts.
摘要:
In an acoustic design support apparatus, a speaker selection supporter selects a desired speaker as a candidate for use in a given space based on shape information representing a shape of the space. A speaker mounting angle optimizer calculates an optimal mounting direction of the selected speaker by selecting a mounting direction pattern which minimizes a degree of variation among sound pressure levels at a plurality of positions on a sound receiving surface defined in the space. An acoustic parameter calculator calculates a variety of acoustic parameters at sound receiving points within the space based on both of the shape information of the space and the optimal mounting direction of the speaker.
