Design and Engineering

HTA Photomask produces quality masks and other products for our customers from many data sources and engineering inputs:
1. Finished Artwork HTA has the capability to camera reduce your rubylith artwork and photoplotted films to provide complete flexibility in the maskmaking process.
2. Engineering Drawing HTA can digitize circuit patterns or devices from your dimensioned drawings. From this data we provide plots for your final approval before the mask making process begins.
3. Gerber Data HTA has developed several mask making options with the use of Gerber data. These options allow us to generate high precision masks with critical dimensions to 2 microns and step and repeat accuracy of less than 1 micron across a large array. Using Gerber data HTA has great flexibility in generating masks for thin film microwave circuits, as well as masks with large die sizes.
4. AutoCAD.dxf Image patterns created by drafting software must be digitized to produce a finished mask. HTA can do this for you. Thereare several easy rules to follow depending on the end mask requirements. HTA can work from any DXF drawing interface file, especially if it is from AutoCAD. If it is not true AutoCAD, but a close facsimile, we will likely be able to use it.
5. Calma Stream GDSII This CAD format has been in use for many years. HTA can work from this format as long as all data meets Calma specifications, and it is alphanumeric with positive whole integers.
