摘要:
A particle therapy apparatus (1) for irradiating a target (5) with a charged particle beam (2) and comprising a particle accelerator and an isocentric gantry (10) rotatable about an axis Y. The gantry (10) comprises a sequence of bending magnets to successively bend and finally direct the particle beam (2) towards the isocentre (20) of the gantry (10). A last bending magnet (15) of said sequence is configured to bend the particle beam (2) in a first plane P1 comprising the isocentre (20) and making a large angle with the axis Y. The gantry (10) also comprises a first scanning magnet (31) arranged upstream of the last bending magnet (15) and configured to scan the particle beam (2) over the target (5) in the first plane P1. The apparatus also comprises a magnetic resonance imaging (MRI) system having two main magnet units (41, 42) arranged on both sides of the isocentre (20) and configured to generate a main magnetic field (Bo) which is parallel to or coaxial with the axis Y. MRI imaging of the target (5) at the isocentre (20) can hence be achieved while or while not scanning the particle beam (2) over the target (5).

A method for etching an organic film 1 having a surface selectively protected by a hard mask layer 2, includes a partial etching process of etching the organic film 1 partly in a thickness direction of the organic film 1 by using a mixed gas containing a gas that anisotropically etches a silicon oxide film and a gas that isotropically etches the organic film without etching the silicon oxide film; and a deposition process of depositing a protective film 3 made of the silicon oxide film on side surfaces 12 and a bottom surface 11 of a recess 10 formed in the organic film in the partial etching process. The partial etching process and the deposition process is alternately performed multiple times.

Disclosed is a low fly height in-plane magnetic image sensor chip. This sensor chip comprises a Si substrate (1) with a pit (2) on the surface (4), a magnetoresistive sensor (5), and an insulating layer (6). The magnetoresistive sensor (5) is located on the bottom surface (3) of the pit (2) in the Si substrate (1). The insulating layer (6) is located above the magnetoresistive sensor (5). The magnetic image surface detected during operation is coplaner or parallel with the surface of the Si substrate (1) surface (3). The input and output ends of the magnetoresistive sensor (5) are connected with leads directly, or bonded with leads through pads (7(2)), or through a conducting post (8) and pads (7(2)) to form connections. And the flying height of the leads is lower than the height of the surface (4) of the Si substrate (1). This technical solution has several advantages, such as compact structure, high output signal, and direct contact with the magnetic image.

The first discrete material layer includes a first material having a first magnetic susceptibility. The method also includes depositing a second discrete material layer having a second thickness dimension over the first discrete material layer. The second discrete material layer can include a second material having a second magnetic susceptibility. The relative first and second thickness dimensions can be selected to provide a desired magnetic susceptibility of the compound material.
